Common problem, unusual cause
Increasing engine temperature generally points towards a low level of engine coolant. However, an interesting case arose in the common VAG 2.0 TDI engine pointing to something completely different. Pierburg investigatesâ¦..

Possible engine complaints:

Engine temperature increases
Engine warning light appears
âShutdown shudderingâ after turning of the engine

The investigation:

Coolant levels were reviewed and appeared to be normal
Engine shuddering pointed towards the air supply system (e.g. air mass sensor, throttle body etc)
A diagnostic tool revealed the following fault code: P2102 - Throttle Actuator Control Motor Circuit
While there was a fault with the throttle body, it was not responsible for the engine overheating
Further investigation revealed that the throttle body and engine fan are protected by the same fuse
These complaints may be due to a defective or damaged throttle body

The remedy:

Investigate the throttle body to see if this is stuck or contaminated with carbon or oil
If this is the case the throttle body is defective and must be replaced
If the fuse has blown, replace it and ensure this has the same amp rating as the one removed!

Did you know?

In practice a number of different terms are used for throttle bodies such as:
- Throttle valve
- Diesel valve
- Intake manifold throttle
- Volkswagen would refer to it as an âintake manifold flapâ

The Range

Pierburg throttle bodies are used in more than 25 million vehicles making them one of the top suppliers of throttle bodies
The range is available same-day or next-day through FPS
