I've a C5 in my workshop that goes into limp home after travelling at above 85Kmh for about 10 Km....
It remains alright doing stop / start stuff around the suburbs, but any prolonged higher speed travel triggers the "Engine Management Fault" warning - though this sometimes come up at slow speeds... the real trigger seems to be the ABS / ESP warning. As soon as it triggers, the engine looses 80% power. This is rather dangerous at intersections, and forget about overtaking entirely!
A computer search of the system revealed a faulty Steering wheel position sensor. This has been replaced, and has fixed a few other issues, but NOT the limp home issue. Despite the Engine Management and ABS mornings sounding and displaying, these DO NOT appear on the faults recording.... (??!!??)
Anyone got any ideas as to what might be triggering this?
