A fault warning comes on around the D for drive indicator on my Signum automatic every few hunded miles and puts the drive into emergecy drive. After being switched off for a period the warning disapears and the car can be driven normally. This has happened 3 times in the last 6 weeks, all seperated by about 2 weeks and several hundred miles of driving but never when driving normally. The local Vauxhall garage has done a full diagnosis but no record of the faults has been recorded on the car's electronics. . We travel to France next week and I am obviously apprehensive of the fault re-occuring then and perhaps not clearing itself after being switched off as it has always done to date. Pages 144 and 154 of the car's owners handbook says the fault is on the automatic transmission, or engine or transmission electronics and that sometimes it can be cleared by switching the engine off and back on again. This is what has happened in my case although the engine off periods have varied so I do not know the minimum time the engine needs to be off to reset the system.
Mike, you have told me to do what the 3 garages that carried out fault diagnosis told me- take it in when the fault light is on.
They though said that a fault that had occurred and then reset itself should still show as a fault code. You say this is incorrect and will only show when the fault light is on.Is this correct?
As you suggest I will have the transmission fluid level checked before we go to France just incase, otherwise I will just have to wait until the fault becomes frequent enough to get the car to a local garage.
To date the 3 faults have occurred when we have not been local.
