Autodata Technical Issue 22 – No response to pressing accelerator pedal on VW Golf Mark VI

31 January 2019

Each month the Autodata team answers a common technical question and provides a printable document with technical diagrams to download and keep, exclusively for IGA members. This month, a VW Golf isn’t responding to the accelerator pedal.

Q. A customers VW Golf MK VI 1,4 TSI is suffering from an intermittent illumination of the engine warning lamp together with a lack of response to pressing the accelerator pedal. When we checked the fault memory we found numerous trouble codes relating to the accelerator pedal position sensor stored. We have replaced the sensor but the problem persists. Is this a known fault?

A. Yes, this fault has been present on many Volkswagen models built around 2011. As you have already replaced the accelerator pedal position (APP) sensor, the problem is probably caused by a poor connection in the APP sensor multi-plug. Access the accelerator pedal, disconnect the multi-plug from the APP sensor (Fig 1.1) and check the condition of the terminals, in particular those used for the supply voltage.

If appropriate replace the affected terminal(s) with a gold plated version using a repair kit available from Volkswagen parts department. Erase the trouble codes and road test the car to confirm the repair.
