A friend of mine owns a 2008 Corsa D 1.2sxi, with 61k, full Vauxhall service history - recently he found that the car was running a little rough and eventually the EML light came on. He took the car to his local VX dealer and had a diagnostic check and general health check done on the car. After the check they have given him details of what they found and say that the oil pressure switch has been leaking oil, which has run down the wiring loom and got into the ECU from there it has run down onto the Lamda sensor getting into the the sensor connection plug. There is a video on the report, which from underneath the car the mechanic points out the oil pressure switch, and the unplugged lambda sensor plug, which is a little oily. They have not told him what fault code came up on the diagnostic check.
They have told him that the car needs a new ECU, a wiring loom and two lambda sensors - at a cost of just under 2 grand.
I have owned several Corsas in the past, and am aware of problems with leaking oil pressure switches but their diagnosis of the ECU being damaged does not seem right to me.
Has any one else encountered this sort of thing before.
I have done a cursory search but cannot find anything similar - forgive me if I have missed the obvious.
