The engine management light was on, and the Golf was certainly not performing as it should, so the owner of this 2008 VW 2.0 TDi asked me to read off the codes and make a diagnosis on the problem.

I found code P2015, indicating an intake manifold air control actuator position sensor/switch, bank 1 - range/performance problem. This is normally a mechanical problem, as opposed to a short or sensor fault. So I made an inspection of the inlet manifold.

This didn’t take too long and I had soon spotted the reason for the code and the performance problems. The answer was to fit a new inlet manifold. With most of the bolts easily accessible, the book time is just over an hour.

Once assembled and the codes cleared, the Golf was fit to go.
