Just like with regular cars, BMW’s, Porsche’s and Mercedes’s need to have regular inspections for optimal performance. This goes especially well with fuel systems as internal combustion engines will not run without them. There are parts in a fuel system that are meant to stand up to years of use, but some parts tend to out last longer than other parts of the system. The system as a whole should be inspected regularly to see what parts of the system need to be check on.  As some parts of a fuel system need to be inspected more often than a others as well as different parts needing different levels of maintenance.

Fuel System Parts To Be Inspected

  • Fuel Filter – The fuel filter needs to be inspected or replaced the most often out of the other parts of the fuel system. Regular inspection is good to keep track of its usage so you know when to get it replace. Filters of a fuel system should be replaced every 10,000-15,000 miles.
  • Hoses – The hoses in which the fuel running to components of the engine bay should be checked regularly. Whenever you have your car serviced, ask your mechanic to check these tubes for breaks, blockage or anything else that would cause concern.
  • Fuel Injectors – Injectors should be inspected annually for performance issues. However, they should be replaced if there are issues with fuel delivery within your engine.
  • Fuel Lines – As with any line in your car, if you see that fuel is leaking under your car then you should have your hard fuel lines inspected. Any leakage should result in replacing those faulty lines for new ones that will not leak.
  • Fuel Pump – Pumps usually last around 100,000 miles but there could be signs that inspection is needed. This happens when the pumps begin surging fuel towards the engine or not delivering enough fuel. You will want to get an inspection regardless of the mileage if any surging begins.
  • Fuel Tanks – Fuel tanks necessarily don’t need to be inspected as they tend to last around 10 years. However, to extend the life of your fuel tank, avoid water and excess moisture at all cost to extend the life of your tank past 10 years.

Performing regular inspections and maintenance will increase the life span of your fuel system as well as providing your vehicle with consistent performance. To schedule a fuel system inspection for your BMW, Porsche or Mercedes call our office today!



How To Diagnose BMW Engine Noise

Most noises from your BMW are the harmless notes of a fully functioning vehicle. Plastic and metal bits from your BMW’s body bump and squeak as they rub together, tires hum against asphalt, wind whooshes past windows, and your engine creates an endless buzz that grows barely noticeable over time.

Most BMW owners know, however, that all sounds coming from your car – especially from the engine – aren’t so harmless. Any noticeable thumping, banging, clicking, squealing or other odd sounds from your engine could indicate a serious problem. If ignored, these underlying problems could lead to major engine damage or failure – both of which pose a threat to your safety and can result in a breakdown. Prevent costly engine repairs and replacement by bringing your BMW to a certified BMW technician at the first sign of these common noises:

Grinding/Screeching: If you hear these noises when turning on your engine it could point to a worn drive belt or pulley.

Hissing or Sizzling: Usually heard after the engine is turned off, these sounds could indicate coolant or oil leaking into the heated part of the engine, a crack in the vacuum line, or an overheating engine.

Knocking/Rough Running: This is one of the most common engine sounds that indicates an issue with ignition coils, spark plugs, and valve gear, or even piston rings and connecting rods.

Whirring: Heard deep within the engine, these sounds indicate an issue with water pump, power steering pump or alternator. If you hear this noise start by checking power steering fluid levels and fill if needed. If the problem still persists, visit a BMW technician for further inspection.

Boston Motor Werks is the local independent BMW specialist you can count on for dealership quality service, maintenance, and repair for all models of BMW. Our certified master technicians are experienced in diagnosing a wide variety of engine sounds and offer complete repair at affordable prices.

When Should I Change My Snow Tires

This is a common question we always receive from customers come the end of winter/the start of spring. Seeing how we living New England and the weather is so unpredictable, it’s tough to provide clients with an exact date on when they should swap out their snow tires for summer tires.

We advise all of our clients to wait until the threat of any snow is completely gone; anyone remember the April Fool’s Day snow storm we had a few years ago?! Many people jump the gun and remove their winter tires the first warm weekend of the season; stop and take a breath, and remember why you purchased these snow tires in the first place, for safety!

Being caught in a spring snow storm without your tires is never a good time, nor is it safe! Summer tires are at their best, when of course the weather is warm; they don’t offer much traffic during cold and snowy weather.

For more information about when to remove winter tires or any other BMW service questions, please give Boston Motor Werks a call at 617-489-0291.

What is that Odd Smell coming from my BMW?

We couldn’t tell you how often a customer calls us in a panic because there is an odd smell coming from their BMW; we ask these customers to describe the scent, and based on their description, more often than not, we will have a pretty good idea what’s going on with your car!

Below you will see some examples of different scents, and what issues they can represent:

  1. If you’re smelling burning rubber, could indicate a number of issues ranging from: drive belts, all the way up to loose hoses. If the hoses become loose, they tend to rub up against the drive pulleys, which is why you’re smelling burnt rubber. If the engine department is hot, do not reach in to untangle the loose hoses, bring it in to us immediately!
  2. Maybe you’re smelling oil? If so, you could have an oil leak that is seeping through your exhaust system; common signs of an oil leak is smoke coming from the engine area, or oil on the pavement.
  3. A gas leak is usually indicated by the smell of gas; a gas leak indicates that your BMW will need a repair in either the fuel tank or injector line or even both! If you smell fuel you should bring in your BMW to us immediately, because a gas leak can result into a possible fire.
  4. Are you smelling a sweet syrupy scent? This could indicate issues with your engine coolant; this is usually related to the car’s cooling system.
  5. The scent of burnt carpet usually indicates some sort of brake issue, which is a huge safety hazard. If you’re smelling burnt carpet, please bring in your BMW right away and have the brakes checked!
  6. The smell of rotten eggs is never a good one, and it can indicate some serious problems with your BMW; it often means there’s a problem with your catalytic converter. Or it can indicate a poor running engine, which leads to the catalytic converter overloading and malfunctioning.

For more information on odors, and what they indicate about your BMW, please give Boston Motor Werks a call at 617-489-0291. We offer free over the phone estimates!

How to Winterize your BMW

As long as your BMW is properly maintained throughout the year, it should be more than ready for New England’s toughest weather; this means following your manufacturer’s maintenance recommendations. This will include fluid changes at their recommended intervals.

We do suggest purchasing winter tires, as New England’s weather is very unpredictable; one day it could be sunny with highs in the 50’s and the next day we could be having a blizzard, so it’s important to be prepared for any weather condition this winter!

If you don’t have winter tires, your car could easily get stuck in just a few inches of snow.

Once you purchase your snow tires, you will be happy you did; once it snows, you can tell the difference between snow tires and regular tires. For one you won’t get stuck, and two it helps you better control your car and skidding and fishtailing is limited!

When Should I Have My BMW Serviced?

When determining time lines to have your BMW services and inspected, you should most often refer to your owner’s manual; this manual will usually indicate the mileage benchmarks where you should have your BMW inspected.

BMW are such high tech cars that the vehicle itself will tell you when you need to have your car serviced; older models have lights that will let you know when you need to bring your car into our shop. The lights are green, but when they turn red, it’s time to bring your vehicle into our garage. We recommend having an oil change when there are about two green lights left (there are usually five total lights).

Depending on which lights are red, we will perform an Inspection I or Inspection II service.

Newer vehicles have condition-based service, or CBS, which the vehicle software calculates service intervals using an algorithm based on various sensors, driving style, average traveled distance, ambient temperature, and other variables. This will actually tell you which parts need to be replaced. For X-drive cars, their transfer case fluids need to be replaced regularly

We recommend performing air and cabin filter replacements every 30,000 miles. Spark plugs on most non-M vehicles should be replaced every 60,000 miles. Automatic transmission service, as well as transfer case and differential service, should be performed every 60,000 miles as well, as part of the Inspection II service. Despite the improvements in synthetic fluid technology, our experience has taught us there is no replacement for old-school maintenance intervals.

When your BMW is in need of some type of repair, maintenance checkup, or a routine service you should have a series of questions in your mind that you already know the answer to! Of course, we don’t expect you to be a car expert like us, but knowing the basis of what your car needs, will help us repair your BMW quicker and more efficiently!

Here are some questions you should ask yourself when you’re thinking about bringing your BMW into a shop:

  • Is this shop I’m considering, of high quality?

If you’re looking for shops, you should first checkout their website, look at the services they have to offer, and maybe shoot the owner an email or give him or her a call to ask for an estimate for a certain repair or service. Also, checkout online reviews; most mechanics will have a couple of reviews. If you’re looking into Boston Motor Werks for your BMW needs, here are reviews about our services on Yelp and Google+ page!

  • What kind of work does my BMW need?

You don’t need to know all of the correct terminology to describe what is wrong with your car; just give us a quick summary of what has been going on with your car: maybe the brakes are making a funny noise, you smell gas, it’s tough to steer, you smell gas, check engine light is on, etc. We will help walk you through your description, and based on this conversation, we will have a pretty good idea what is wrong with your car!

  • What is the price of the repair?

Before you make your final decision, make sure you ask the shop for an estimate; most shops will provide free estimates for any repair or service that needs to be done to your car. Here at Boston Motor Werks, we always offer free estimates for any car we are about to work on!

Here at Boston Motor Werks, we always take care of our clients! We will provide the best repairs, using only original BMW parts, and our prices are always more than fair! We offer dealer quality repairs, for a more affordable price!

How to Maintain your BMW

You worked hard for the luxury of owning a BMW, let us help you maintain a well running machine! We believe that your BMW should go through regular maintenance checkups, just like you go to the doctor every few months or so for a physical.

This maintenance checkup is recommended for all cars, no matter the year or model of the BMW. Regular & Preventative Maintenance will help you avoid large repair bills in the future; so many issues on cars today can be avoided by following proper maintenance procedures.homescreenpics3

There is and never will be a replacement for “old school” maintenance programs; despite advances in part and fluid technology that supposedly extends service intervals.

Oil changes are one of the most important parts of maintaining your BMW; dealerships and us have a differing opinion regarding oil changes. Dealerships recommend an oil change after 15,000 miles! Here at Boston Motor Werks, we recommend a synthetic oil change after 5,000 miles (for mineral oil cars, we recommend an oil change at 3,000).

Waiting for the 15,000 mile mark can lead to potential engine wear and damage. In the past we have seen pre-mature failures for a variety of parts, ranging from valvetronic eccentric shafts and levers, to crankcase vent valves, all the way up to standard engine seals; this is all due to not having their oil changed after the 5,000 mile mark, you combine that with New England weather and traffic, and it’s a recipe for disaster!

Once your car has reached 30,000 miles, we will perform an Inspection I, which includes an oil change, cabin filter, and if needed and often recommended, an engine air filter. After 60,000 miles we perform an Inspection II, where we will perform an oil change, engine air filter, cabin filter, fuel filter, and differential fluid flush.

Our goal is to help our clients save money in the long run, and one sure way to do this is by following a strict maintenance program; these programs will help you avoid big expensive repair bills in the future!

How to Maintain a Cleaner Fuel System in your BMW

Due to the poor quality of fuel these days, fuel systems have become more complicated and increasingly sensitive. Over the past few years, we have seen BMWs experiencing fuel pump and fuel injector failure due to poor fuel quality.

Carbon build can cause some serious damage to your car’s combustion engine; it causes increase fuel consumption, decreased performance, and poor running characteristics.

The way we can help improve your fuel system is by installing a fuel injection system that plugs directly in the fuel rail and thoroughly cleans the fuel injections. This is the most effective way to clean your system, without completely removing the system.

This service will help your BMW run more smoothly, the way a luxury car should. It not only improves the fuel efficiency of your vehicle, but it also increases the power and performance; this service is available for just about all recent models.

What Happens When Your Check Engine Light Comes On?

If the light does turn on, bring on down to our shop located in Belmont MA, and we will inspect your car and diagnosis the problem right away.

If you’re trying to renew your state inspection sticker, and they see that you’re check engine light is on, they will not pass your car for another year. Here at Boston Motor Werks, we will run tests that will help us diagnosis the problem quickly and efficiently.
