If you are experiencing a vacuum leak in your BMW, you know that it can be maddening. A leak is a common problem that we run across, and we can diagnose the issue and fix it for you. Let’s discuss vacuum leaks in BMWs and how we can help you repair them.
When an engine runs, it creates a vacuum inside the cylinders. If a hose fails, or there is an issue with the engine, you may encounter a vacuum leak. This allows additional air to enter the engine, which results in an incorrect air to fuel ratio. These are the common symptoms of a vacuum leak:
Check Engine Light: If your car’s computer detects that you have a vacuum leak, it will illuminate your check engine light. This light may come on for a number of reasons. If the light has been triggered, take it to a technician, who can perform a diagnostic scan to find the trouble code.
Stalling: If the air-to-fuel ratio is incorrect, this can cause your engine to stall or die.
Trouble Starting: Having an incorrect air-to-fuel ratio can make it hard for you to start your car.
High or Rough Idle: If your engine is receiving too much air, it will idle faster than it should. Your car’s computer will compensate for the amount of air the engine is receiving. This will lead to fluctuation idle speeds.
Hissing or Sucking Sounds: If you can hear a hissing or sucking noise, you probably have a vacuum leak.
A damaged or disconnected vacuum hose is the most common cause of a vacuum leak. These hoses are made from plastic and the extreme heat from the engine can cause them to wear out and break over time. The fittings can also break and cause the hose to be disconnected.
Worn out seals and gaskets can also cause a vacuum leak. Seals and gaskets are used to keep in fluids while keeping out debris. They also provide an airtight seal. Over time, they can dry out and crack leading to an air leak. This type of cause can be hard to detect.
Some vehicles use a brake booster to power the braking system. If it fails you can experience a vacuum leak.
Damaged or broken parts can also lead to problems with this feature. Vacuum hoses connect to many different parts. If these connections fail, this can also lead to a leak.
Since there are so many issues that can lead to a vacuum leak, it can sometimes be difficult to narrow down the problem quickly. By having regular maintenance performed, you will help to lessen the chances of acquiring a vacuum leak.
The engine is a major part of your BMW and it needs to be taken care of. If there is an issue that could be affecting it, it needs to be taken care of right away. Letting an issue go without having it fixed can lead to engine failure as well as higher service bills. Taking care of any issue that arises right away will save you time and money in the future.
