I have a 2010 corsa diesel which has a problem in that it goes into limp home mode after a few seconds of high power use, the service light comes on whilst driving.
Unfortunately the OBD2 port has been graunched so I cannot get a reader to plug in.
However opel derived cars do have an older diagnostic mode accessed by switching on the ignition with both throttle and brake depresses then counting a series of service light flashes. The problem is that this gives a 4 digit code that is not the same as the OBD2 codes. Typically starting with 6, e.g. 6352. I cannot find an interpretation online so has anyone ideas?
