Engine code is AUQ I was wondering is there an ignition amp on the car as epc light and traction control light is on and car won't start there is no spark I have changed relays changed crank sensor checked cam sensor checked coils and car still won't start

there was water in ecu I have dryed out should I replace it or not please help car has been stood for 2 weeks now and I'm stumped for a solution

has it been on vcds? needs a read to know where to start looking. wet ecu doesn't sound good though :(

Yeah I've had it on vcds and it came up with loads of faults I saved them then cleared them it just keeps coming up with one now ECM relay I have replaced the 2 in engine bay but there still now spark

There is no ignition amplifier, each plug has its own fully functioning coil.

 

Water in the ECU is bad, but you cannot simply just change it.

 

You need to code any replacement to the car, otherwise it still will not start. To do this, you'll need VCDS and the 4 digit SKC PIN of the current instrument cluster, and the one from the donor car.
