finding faults

[softtop]

Is it possible to have fault codes stored in the ECU if the problem appears to have gone away?
The car has hesitating when you put your foot down for a while and today the problem maybe showed itself when the battery warning came on. Later it went out?? This was all during a stint on the motorway? Confused, yes!

The hesitation combined with your other post about overheating might indicate blown head gasket(s)

I'd get it checked out with a compression test.

Yes.

Thanks, I will do. That does not sound like good news....

Equally no as well. It all depends.... If the ECU is disconnected from the power it is lost. If other faults occur during the testing then it is possible for those codes to supercede/replace the original one that was related to the problem. The fault code is also a bit ambigious as there are no time stamping information so the code may be nothing to do with the original fault and was simply not cleared.

Quick update. The head gasket is fine, no blown bits to remove cash from the pocket!
Engine temperature appears to match the gauge also. No problems there. Listening to the relay of the fans coming on maybe an issue, not sure. Instead of a clean switch it buzzes for about a second during switch on, time of buzz is so short I cannot say if fans are already on at this point. Does this mean the relay could be faulty?

Save your time and effort.

If there is a genuine problem the ECU will register a fault code.

These are quite specific and may allow you to home straight in and find the responsible component quickly and easily.

No.

But then my Freeserve account is becoming totally cr@p at spotting the difference between genuine mail and spam so probably ate it.

Maybe 'softtop' is a bit naughty to a spam filter - tee hee!

Anyway - would you like to try a fault code reader?
