Arghh help !! Yellow engine light on my smg m3

Last time I had the yellow light on ( not so long ago ) it was coilpack 4 that had ceased . but this time it looks like a different matter

The car is running in limp mode ( feels as rough as anything )

Have read with carsoft and got the following errors :
.................................................. .............................................

DME/DDE - Status : ERROR - 132 HFM reference tension
.................................................. ............................................

EGS - Status : ERROR - 97 Term. 30 supply for EGS SG

EWS - Status : ERROR - 01 Key 1 not recognised
Key recognising procedure during the start process :

En sends the key data to the EWS control unit.
- The EWS control unit controls the data, and then sends the permission signal to the engine control unit (DME/DDE) en de starter
- After starting the EWS control unit calculates new data (changing code) and then sends it to the transponder into the key.

LKM/LCM - Status : ERROR: - 40 Thermical Oil Level Sensor

I have cleared the faults but the DME still reports an error and it still sounds like a tank and the yellow light is off , but I havent driven it anywhere .


Can anyone shed some light on to what the fault maybe

Try cleaning your HFM. Mine did the same when I got it, replaced all the coils and fixed it for a couple of weeks and it came back. It was the thottle actuator that was getting stock.
