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 investigates…..
Possible engine complaints:
- Engine temperature increases
- Engine warning light appears
- “Shutdown shuddering” after turning of the engine
- 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
Did you know?
- 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!
- 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 ‘intake manifold flap’
- 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
