If car was running allright and the ECU light off till they done camshaft and lifters ,I would get them to recheck timing .The also said ECU faulty and Vauxhall said not . I would take car to a garage more qualified , equipped and capable of diagnosing and rectifying faults.Did they not scan car ? Dont know how replacing timing chain would damage camshaft .

Thankyou for reply, picked car up today from garage, yes a good garage, saw paper work from vauxhall saying not ecu fault they have tried coil,plugs and injectors.

Car from cold drove fine for a mile then ecu light came on flashed first then stayed on and car was running on 2 cylinders only.

They say take it to auto electrician and are saying about £200 to pay them but as not fixed have not paid so far.

the cam shaft had dents at one end, they showed me it.!

compression was normal so far paid £900 for car and then £650 on the work carried out the light was not on before cam shaft replaced vauxhall say it does not need reprogramming.

Thanks again
