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.

What is a vacuum leak?

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.

Finding the Problem

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 regularmaintenance performed, you will help to lessen the chances of acquiring a vacuum leak.
