None of these faults will clear, ive checked clocks for loose plug, checked+run an earth to ecu. I cant access engine ecu,only the above ecus.

Spoke to main dealer+ tech. reckons im probably right condeming engine ecu(any problems on W line (german for immobiliser) is always engine ecu).

Anyone had same faults ?, im going to send off ecu , but ?50 to test +not many companies will look at this ecu. So i thought id post this out of curiosity.

Best to pin out ecu, live and earths and communication and immobiliser line if all, present get reset unit off ebay and program using op-com m8. On this model you can read security code from instrument cluster using op-com, Then you can program ecu using security code and op-com
