Common Repairs on Mercedes-Benz E Class 2nd Generation Cars

For Mercedes enthusiasts, they know that the Mercedes-Benz W211 series is a great luxury car to own and drive around. Nothing says luxury and comfort than a Mercedes. However, a Mercedes is a car and all cars at some point in time need to have repairs done. If left unchecked, small problems can lead to major repairs and bills. To prevent these major bills from coming your way, we have laid out common problems you may run in with your Mercedes. If you notice any of these issues, be sure to contact a specialist as soon as possible.

Jerking Transmission – A common complaint with this series is that when shifting from first to second gear, they will feel a jerking or jolting sensation. This could be a sign of a problem with the car’s transmission and you should have the system checked out immediately.

A/C Problems – Just like with most cars, you may run into a problem with the climate control system. You may have the A/C produce warm air instead of cold and at some times, may not turn on at all. This could be a sign of an electrical problem. Contact a repair shop to have your refrigerant looked at.

Parktronic Display Sensor Malfunction – The Parktronic system is an array of sensors that help tell the driver of objects while parking. If this system is malfunctioning in the sensor display then you may need to have the system reset.

Fuel Gauge/Range Indicator Problems  – You can bet there is a problem with your gauge if you start to see some weird looking readings on your fuel and range indicators. If you see this then you will need to have your system check out so that you get the proper readings you desire.

Battery Drainage/Alternator Problem – Always schedule regular maintenance to ensure that your battery is working properly and there is no unnecessary drainage. If you are having problems starting your car then you may need to have your alternator checked out as well.

How To Winterize Mercedes Vehicles For Winter Storage

amg-1880381_640

The winter time is usually a rough one for vehicles both regular and in the luxury department. With colder temperatures, slick road conditions, and snow there are a lot of precautionary measures to take. With this in mind, some Mercedes owners will opt to put their luxury car into store much like other owners. That way they will not have the salt from ice melters ruin the paint of the car as well as have their vehicle be in any danger due to road conditions. As we are specialized technicians for Mercedes we have compiled a list of things to do in order to prepare your Mercedes or other luxury vehicles for winter storage.

6 Winter Tips for Storing Your Car This Winter

Fill Up The Fuel Tank

One of the worst things you can do is leave a car parked for months with a nearly empty fuel tank. The empty space in the tank will contain vapor which will condense into water over time. If there is water present in your fuel tank the gasoline will get contaminated and corrosion starts to appear which can affect the fuel level sensor. If this is to happen you could potentially have a broken or faulty fuel gauge which can be dangerous.

Routine Maintenance

This goes for regular car care, especially for Mercedes vehicles, that having routine maintenance done to your vehicle is important. If your Mercedes-Benz is nearing their maintenance for any of their services such as Service A, B, C, D, E in the next 500 miles or 30 days, you will want to have it checked. That way when you take your car out of storage it is all ready to drive.

Tire Pressure

When it comes to cold weather and sitting idle, the pressure in car tires tends to dip. If you are thinking of storing your luxurious Mercedes for the winter, add air to your tires so that they reach a level of 40 psi. By doing this, you will minimize the flat spotting of your tires while in storage. On top of that, the car will be ready to hit the road at the first sign of spring.

Use A Cover

If you are going to store your car this winter, you should consider purchasing a car cover. Why would you need a cover if your car is in storage? No matter if it is outside or inside, the car’s paint can be damaged by almost anything from the weather to dust mites forming on the car in storage. To prevent spending money in the spring for touch ups or a new coat of paint, get a cover for your Mercedes. This will keep it looking mint through the winter so you can drive a car that looks like new in the summer.

Disconnect Battery

If you are dead set on storing your Mercedes for several months during the winter season then it is recommended to disconnect the car’s battery. This way you will not lose any battery power during the winter as it sits in storage. Once the springtime arrives there are a couple of things you need to such as synchronize the windows. To do this you will need to press and hold the window switch for five seconds once the windows hit the top.  If your Mercedes is equipped with a sunroof, you will need to move it all the way back and then hold the switch for five seconds.  You should also do this same motion but have the sunroof move to the front and hold.

Once you reconnect the battery to take the car out of storage, you will need to reset the steering angle sensor otherwise you will have an ABS, ESP defective warning on the dashboard. To reset, start the car and turn the steering wheel all the way to the right and left a couple of times then restart the car.

Fluids

If you plan to store your Mercedes for the winter you should make sure you have all the necessary fluids in your vehicle. Your coolant should have a 50/50 ration of water and antifreeze, and if you live in very cold climate the ration should be 30 water and 70 antifreeze. You should also make sure that you have windshield washer fluid that will not freeze at low temperatures as your car sits in storage. In all, you just want to make sure that there is no water that could potentially freeze any lines and cause leaks once the winter surpasses.

With the first snow of the season arriving over the weekend, it is time to seriously consider prepping your Mercedes vehicle for the winter season. While there are basic tips to perform on any car for the winter, having a Mercedes or Mercedes-Bemz vehicle means you need to go the extra mile. You always want to make sure your car is looking and performing like the luxury car you paid for. This goes especially for the winter as colder temperatures can affect engine performance and the road conditions can affect how safely your vehicle will operate. As we specialize in Mercedes repair, we have come up with a quick checklist to perform on your luxury Mercedes car that will prep it for the winter time.

Mercedes Maintenance Winter Checklist

  • Schedule a Tune-Up – If you own a car you are bound to run into car troubles, add in the winter weather and those problems only double. By scheduling a tune-up you will ensure your car’s performance while getting a leg up and preventing any costly repairs down the road.
  • Check Tires – Keeping an eye on tire tread and pressure are a given but is especially important to monitor during the winter. With the snow and ice on the roads, you will want to make sure that your Mercedes vehicle will not slide on the road.
  • Change Oil & Filters – Performance for luxury and high-end cars such as Mercedes is very important, its one of the main reasons people purchase these brand cards besides the name. You want to make sure that the performance is in its optimal form. In the winter you will want to change our your oil as well as have a technician replace any fuel, air or transmission filters.
  • Check Lighting – The winter season is darker than the other parts of the year, which means having your lights checked is extremely important. Be sure to have both interior and exterior lights, especially headlights, inspected to make sure they work properly.
  • Inspect Brakes – One of the most important things to have inspected for the winter is your brakes. To be prepared for the unexpected make sure your braking system is up to code with nothing hindering your safety in the snow.
  • Test Battery – With the extra terrain to move through and colder temperatures, it is more likely in the winter that our battery can lose a good amount of power. Be sure that your Mercedes’s battery performance is checked.
  • Inspect Exhaust System – Just like with your engine or battery, your exhaust system can be affected by the colder climate and snow. To ensure optimal performance, schedule an inspection for your Mercedes exhaust for ensuring safety this summer.

What is a Porsche Active Suspension Management System?

Since 2005, Porsche has been installing Posce Active Suspension Management (PASM) system in their cars. What this system does is provide improved grip and greater comfort while you drive your Porsche vehicle. What makes this system so unique from a standard damper is that it does not have a control wire that is connected to the head of the unit. What the PASM has is a central control unit that is connected to all four dampers that send out an army of sensors that spring into action at the push of a button.

What these sensors do is they measure parameters such as steering input, body roll, and suspension bump while you drive your Porsche vehicle. This data is sent back to the control unit, where the PASM system determines whether to stay in normal or sport mode.

Normal Mode

In normal mode, the valves controlling the channel are open, which allows for a greater flow of oil, resulting in a softer damper.

Sport Mode

In sport mode, the dampers stiffen as the bypass channel is closed. This allows for greater cornering performance by maintaining the tires’ contact with the road. By closing the bypass channel, there is an increase in the compression needed to force the oil through the damper body. Creating a stiffer damper and a more responsive Porsche vehicle.

What is a PDK Transmission?

When it comes to transmissions, high end brand cars are always looking for the best technology and engine parts to put in their models. Porsche has done just that with their Porsche Doppel Kupplings (PDK) double-clutch transmission. What makes the PDK different from standard dual-clutch transmissions is that it uses hydraulically actuated wet clutch packs one enveloped around the other.

The PDK is broken down as such. One clutch connects reverse, the first, third, fifth and seventh gears, while the other handles the second, fourth and sixth gears. Instead of a clutch pedal on the floor, the PDK has an electronically controlled valve body that actuates the correct clutch when needed. The PDK system engages one clutch at a time. However, because gear sets alternate between clutches, as one disengages the other can engage in one fluid motion.

The PDK transmission system avoids damaging parts with launch control by effortlessly switching from one clutch to the other, as the system engages one clutch at a time. By doing this, the oil-soaked wet-clutches don’t overheat and wear out under pressure.

For more information on the PDK transmission and other Porsche services we provide, contact us today!

What is Porsche Dynamic Chassis Control?

With any car, if you are driving and cornering you will feel the weight of the car roll towards the outside tires. When this happens, it means the loads experienced by each tire are no longer even. To fix this issue, Porsche has designed an electrohydraulic antiroll bar system called Porsche Dynamic Chassis Control (PDCC). This system results in more responsive handling when cornering with Porsche vehicles. What makes this system different is that the PDCC uses hydraulically actuated cylinders to mechanically alter the load on both the front and rear antiroll bars.

The PDCC also uses sensors to measure the movement under both bump and rebound for each damper. With this information the system will know how to load both antiroll bars as you drive. Each corner of the car has cylinders that move in the opposite direction to the dampers of the PDCC system. With this movement, the camber of each wheel works at optimal levels, while ensuring the right amount of load is transferred from wheel to wheel while cornering.

This system designed by Porsche is great as it ensures a more direct turn in, while make the car’s stability is at its optimal levels while cornering.

4 Warning Signs You Need To Get Your Brakes Replaced

Brakes are one of the most important aspects of your vehicle whether you have a BMW Porsche, or Mercedes or any other type of car. This is because these devices keep you safe as well as preventing the car from driving through unwanted places or things. When it comes to brakes, the only sure fire way to know if you need new brakes is if you take your care for a scheduled inspection and get results back saying you need a replacement. There are other factors to look out for while driving that are actually warning signs that you need new brakes.

Here are some signs of brake problems to look out for. If you experience any of these you should visit your repair shop or see a specialist as soon as possible.

Reduced Responsiveness or Fading

If your brakes are not responding as they normally would and should then this could be taken as an indication of a leak in the braking system. Another sign of a leak is if the pedal sinks towards the floor of your car. The type of leak could be either air or brake fluid but both require an inspection. The oldest way to figure out if your brake fluid is leaking is if you notice a small puddle of fluid when your car is parked.

Pulling

If you are braking and your car starts to pull to one side it may be a sign that the brake linings are wearing unevenly. Another cause of this pulling motion is if there is some sort of foreign matter in the brake fluid. If either of these reasons are causing any pulling while you brake then you may need a brake adjustment or to have your fluids drained and replaced.

Grinding or Growling

If you start hearing a grinding or growling sound while you apply brakes to your car then your brake pads have been worn down completely beyond replacement. This noise is caused when the two metal pieces of the brake rubbing together. The longer you drive with worn down brake pads, the more likely you are to “score” or scratch your rotors and creating an uneven surface. Once the rotors are uneven, you will need to have them “turned” by a professional or replaced depending on the damage.

Vibration

If you are driving, applying the brakes and notice a vibration or pulsating brake pedal then it is a sign your have warped rotors. Not to be confused from vibration when your vehicle is our of alignment, if the vibration occurs during braking situations when the anti-lock brakes are not engaged then it is a sign of warped rotors. This vibration is felt because the brake pads are not able to grab the surface easily.

Maintaining Your BMW During The Winter

Those that live in New England know that the winters here can be harsh and brutal. While we protect our home and selves from the cold and snow we need to also thing about our cars as well. Without proper maintenance before the winter season, your car can encounter problems as the winter months progress. This is especially so for BMW owners as BMW are more than just a car, they are a way of life. A lot of the tips mentioned below will seem like common sense but in reality, many people tend to overlook. Here is what you should check up on before the winter season is in full effect.

Internal Maintenance

When the temperature drops, the fluids in your car can be severely effected which could prevent your BMW from running properly. Ensure that your antifreeze and the viscosity of your BMW oil are at proper levels for optimal performance. Hoses and belts can also be effected by the sub zero temperatures so be sure to make sure nothing is wrong with these components. With all of the snow, water could seep its way under your hood and damage your engine and other components such as your car’s battery. Check for any corrosion on the battery during the fall so you will not have battery problems in the winter. As with every scheduled maintenance, the winter season is a great chance to get an oil change as well!

Exterior Maintenance

When you think of winter time and cars, you think of all the salt that will be on your car eating away at the paint. Be sure to wash your car to remove any salt that could corrode your paint as well as keeping your tail lamps, headlamps, and windows clean as well. Other things to keep in mind is the traction of your car as well as the windshield wipers as these are two very importance things to have working properly in the winter. If you feel your tires are not well equipped for the slippery snow then trade them in for snow tires during the winter. Make sure your windshield wipers are not tearing apart so they can handle the heavy snow to come.

Preparation is Key

When it comes to maintenance in general and not just for the winter you will need to be prepared with the right equipment handy. Keep pressure gauges at the ready to check tire pressure as the winter gets worse and worse. You will also want to have spare fluids, jumper cables, a flashlight and batteries ready as well for any emergency case. With the winter, you will need to stock up on winter-specific supplies such as ice scrapers, blankets, and snow brushes.

Difference Between A & B Servicing For Mercedes Vechicles

When it comes to owning a car, having regular maintenance and repairs is necessary and vital to extending the life of your car. For the most part, repairs and scheduled maintenance comes pretty standard across most brands of cars. However, German automakers such as BMW, Porsche and Mercedes often have specialty repairs that need to be treated by trained technicians or specialists. With Mercedes, the company has made it so the maintenance needs are usually separated into two selections; A service and B service. Here at Boston Motor Werks, we have technicians for each BMW, Porsche & now Mercedes vehicles to ensure the proper maintenance is applied. Each technician are highly trained in their field to offer optimal services to our clients. Our Mercedes specialists are knowledgeable for both types of services whether it be A or B.

Whenever your Mercedes machine is ready for either of these services, you will receive an alert from the car’s computer system letting you know its time for an inspection. Once you bring your vehicle to our shop, our technicians will know exactly the type of service to perform based on our diagnostics software in combination with your car’s computer. The big thing that confuses people with Mercedes services is knowing what comes with each service. Below is the differences between each service and what to expect when taking your Mercedes vehicle in for a repair.

Service A

Like with moth services, the frequency of getting repairs is based upon how often you drive your car, how long, how you handle your cars as well as other factors. For Mercedes, if your car was made after 2009 you will need to service after its first year or at 10,000 miles on the road. Then again after every two years or 20,000 miles. Maintenance that often comes with Service A includes:

  • Replacing oil filters and synthetic motor oil.
  • Checking levels for all fluids and adjusting them to factory standards.
  • Checking and adjusting tire pressure.
  • Inspecting brakes for any issues.
  • Resetting your car’s internal counter for the next Service A visit.

With any car service, our specialists take into account of your cars year, make and model to gather the right sheet of information needed for the service. That way we ensure the most proper maintenance for your exact year and model of car. We are proud of our machines and want you to feel comfortable that your car will come out performing at its best.

Service B

Just like with service A, service B varies on your vehicles specifics as well as when it was made. After 2009, you should have your vehicle brought in after every 20,000 miles or every two years. The specifics of Service B maintenance for Mercedes is as follows:

  • Replacing oil filter, synthetic oil, cabin dust filter and combination.
  • Exchanging brake fluids and inspecting brakes for any issues.
  • Checking tire pressure.
  • Checking fluid levels and adjusting to factory settings
  • Resetting the counter for the next Service B inspection.

6 Signs Your Car Needs Suspension Repair

Suspension, or shocks, are a great thing on a car as it makes your drive comfortable and bump free as much as possible. After many miles and supporting the weight of your car, eventually you are going to need a suspension repair on your vehicle. With suspension being associated with smooth rides, they tend to not be treated as important as other car repairs. However, having a faulty suspension can greatly affect your ability to control your vehicle, especially during turns, so it is best to not skimp on getting your suspension looked at by a professional.

Below are six signs to look out for that are good indicators that your vehicle is due for a suspension service.

  1. Car Rides Roughly – This is one of the most common indicators that your suspension may need to be replaced or repaired. When drivers start to feel their ride to become bumpy or even if the body of the car bounces at every bump, then it is clear that they need to see a mechanic.
  2. Drifting – If you have a suspension that is not properly working you may tend to feel the car “drift” or “pull” when turning. This basically means that the shocks are no longer keeping the vehicle body centered against the centrifugal force of the turn. When this happens, you increase your risk of rolling the car over. The minute you feel the drift or pull when turning you should go to a repair shop.
  3. Dips When Stopping – With worn out shocks, you may experience the vehicle body lurch forward and downward, nose-first, when you apply your brakes firmly. When this happens, the ability of stopping the car quickly can be affected which may cause to collisions.
  4. Uneven Tire Treads – You may not think they are related but a bad suspension can affect your tires. Check your tires and their treads to see if there is any uneven wearing or balding spots. These are actually symptoms of a suspension that is not holding a car evenly.
  5. Damaged, “Oily” Shocks – Take a look under your vehicle and inspect your shocks. If you start to notice that they are becoming greasy or oily, there’s a good chance that they are leaking fluid. A leak is a good indication that they are not working properly and they need to be replaced.
  6. Bounce Testing – If you just have “that feeling” that your suspension is about to go, try testing it with the “bounce test.” With the car in park, press down the front end of the vehicle with all your weight and bounce it a few times then release. After that, do it to the rear of the car and if you notice that it bounces two to three times after releasing then you were right and the suspension is wearing out.
