Hello I wonder if anyone on this forum could help me? Last week my wife's 2002 1.2 VW Polo started loosing power, then an yellow engine warning light appeared. We stopped using the car and took it too a local garage. After a diagnostic check was carried out a fault was located with the EGR valve, this was replaced and the car was still down on power. A map sensor was replaced and no fault codes were displaying. I have picked up the car this morning and it's still way down on power, and after a short drive the engine was very warm, although the temp gauge was not showing this. Would anyone be able to shed some light on what they think is the matter? I would really appreciate this. Thanks :-)
