Hi all, am new to the group and after 9 years of trouble free motoring I was recovered by the RAC for the 1st time, with what I suspected was a misfire but even more so.

I go this report from them and wondered if anyone could potentialy tell what might be wrong and who would be best to sort my issues out in the south of the uk.

System Type: ENGINE SYSTEM TEST/VALUES Name: BBK - MOTRONIC DTC: 18010,+30 voltage DTC: 18630,O2 Sensor Signal Stuck Rich - Bank 2, Sensor 1 DTC: 17981,Left engine mount solenoid valve; open circuit DTC: 18080,Cooling fan 1; short circuit to ground or open circuit DTC: 16684,Random / multiple cylinder misfire detected DTC: 16685,Cylinder 1 Misfire Detected DTC: 16686,Cylinder 2 Misfire Detected DTC: 16687,Cylinder 3 Misfire Detected DTC: 16688,Cylinder 4 Misfire Detected

Any help or advice would be much appreciated. Thanks in advance.

Hi it sounds like an ECU problem at source, get it removed and sent off for testing, any half way decent independent garage is capable of doing that for you.
