If it's like mine when the cam sensor failed it will need to be cleared.

Ok thanks lads she's driving fine no probs at all with z3 but that bloody eml is on and it's right in your face when your driving my mechanics on holiday this week so taking it next Monday to have light reset changed thermostat housing which was code that came up and it's come back on agian my mechanic recons it's a wiring fault and is gonna have look Monday hope he sorts it
EBay C110 and make sure you get the cable adaptor in the kit. This is the one I have and it clears most codes. Takes a little getting used too but great once you have mastered it.

Just ordered this on your suggestion. Bought a different unit to use with my computer but the lap top is too old so will give this a try! JIM
Thanks for advice everyone ordered a c110 code reader off eBay pluged it in to z came up with p0170 code and I found a crankcase breather pipe disconnected sorted that and erased codes eml light not come back on for 2days think I've cracked it code reader well worth it £36 on eBay happy daze
I hope so, I just bought one too!! JIM
Does anyone know what problem could be eml light came on again on z3 same code again code reads as ab check fuel supply (euIII p0170) been ok since reset 5days ago car drives fine and I've just reset it looked on line and other people are saying vacuum leak or maf sensor or fuel pump any ideas
@Jlp, have a read of this .
Potential causes include a vacuum leak, unmetered air leaks Fuel saturated engine oil Leak in turbo air charge hoses (if equipped) Possibly bad O2 sensor (If Mercedes, may require adaptation with M-Benz compatible scan tool.) Oil contamination in MAF connector or O2 sensor connectors. Also check ignition coils, cam and crank sensors, and oil sensor for leakage contributing to oil intrusion in wiring harness. Defective MAF (Mass Air Flow) sensor (especially on Mercedez-Benz and other European autos. There are a lot of problems with aftermarket MAF sensors.) Defective fuel pressure regulator Leaking camshaft adjuster solenoids (Mercedes-Benz).
