Ok so on my way to work this morning the car started going really badly and seemed to lose power. The engine management light then came on and was flashing. As I was literally in the car park when this happened I parked up and switched it off. Now a guy I work with has vagcom and after work he plugged it in and the faults that came up were:
Rear heater core temp sensor (G154)
Coolant temp. sensor at engine outlet (G82)
The car was now running fine with no engine management light. I was then driving for about 5 minutes when the car started almost chugging when I went to accelerate. To me it seemed like a misfire. So once again vagcom was plugged in and nothing different came up. Car is now running 100% with no problems. I will go out later for another drive when the engine is cold.
So has anybody experienced this before and are the fault codes above the problem? I should add that the only modification is a forge spacer.
Any help is greatly appreciated.
