How to Identify Camshaft Tensioner Leaks in Your Audi

Audi vehicles are known for setting and exceeding performance standards. When these qualities are matched with the sleek exterior and luxury interior design that Audi is known for, then you have one of best all-inclusive vehicles around.

When it come to owning one of these all-inclusive vehicles, you will want to ensure that your Audi remains this way. So this means that it requires proper maintenance to be routinely completed. Even when you stick to a maintenance schedule, there will be times where parts might unexpectedly need attention. One such part is the camshaft tensioner.

One of the major issues that is commonly seen with the camshaft tensioner is leaks. To find out more information about the camshaft tensioner, how to identify if a leak is occurring, and where to go to have the camshaft tensioner leak fixed, we have provided you with this quide:

The Function of the Camshaft Tensioner

The camshaft tensioner, also known as the timing belt tensioner, is responsible for keeping the appropriate amount of tension on the cambelt or timing belt. The cambelt is responsible for synchronizing the camshaft and the crankshaft.

Accurate synchronization of these two systems needs to be in place for the engine valves to open and close at the proper times. To maintain the appropriate level of tension, the camshaft tensioner requires fluid and lubrication to ensure its connected parts run smoothly. If the camshaft tensioner is faulty with a leak, then the engine of your Audi is not going to function in the optimal condition that you are used to.

Tips to Identify Camshaft Tensioner Leaks

Every part of your Audi should work together so that the performance level of your vehicle remains high. This cannot happen if your camshaft tensioner is leaking.

A leak in the camshaft tensioner is the most common repair that needs to be addressed when it comes to the camshaft tensioner. The leak is most likely going to come from the camshaft seal.


The first tip and sign that your camshaft tensioner is leaking is if you hear a loud clicking or grinding sound. When a leak has occurred, the camshaft tensioner is not able to maintain the proper amount of fluid on the cambelt. This leads to the loosening of the cambelt and when the cambelt is loose, it can cause vibrations to occur underneath the hood. With these vibrations comes irregularity in the opening and closing of the engine valves. So, clicking or grindings sounds will be heard both while you are driving and while you are idle.

Acceleration Problems

Another tip and sign to look for when it comes to a leak in the camshaft tensioner is problems with accelerating. Without the necessary lubrication that the camshaft tensioner provides, the cambelt can stretch or snap. This wearing of the cambelt means that there is no longer control over the engine valve opening and closing.

As previously mentioned, these valves need to be in perfect synchronization to ensure optimal performance. When this synchronization does not happen, you will feel your Audi hesitate as you are stepping on the gas pedal. Then you will know that there is a leak in the camshaft tensioner.

The Warning Sensor

One last sign and tip you should be aware of when it comes to a camshaft tensioner leak is if your check engine light is on. Your Audi comes with a very sophisticated computer system that allows your to monitor your vehicle’s components. When one of the sensors indicates an issue, the computer will alerts you via one of the lights on the dashboard.

As there are many different components under the hood, it is not practical to have a light on the dashboard for all these systems. The check engine light does that job, so when there is a leak detected in the camshaft tensioner, this light illuminates.
