Vag com engine faults cleared themselves?

[Fidge]

I have recently just got an Arosa 1.4 PD TDI and it has just failed to start a few days ago! The starter motor cranks but she doesn't fire up!

I plugged in vag com today and earlier got 2 engine faults come up, think one was the N249 valve? Anyway didnt log them and went to check again earlier and the faults have now cleared by themselves! Checked 4 times and now coming up with "no fault found" I haven't cleared the faults and she still doesn't start can anyone help please?

cheers

Nothing special to say here, each fault code has a specific reset counter, that clears it after a certain amount of ignition and/or warm-up cycles. It's also possible the ECU simply lost them but that would be rare.

But the fault still exists so shouldn't a new code flash up after I tried to start motor again!?

Post an Auto-Scan please, doesn't matter if it actually contains codes or not.

Anyone shed anylight please? Is this the valve at the back of the engine next to the water bottle? As this valve is clicking like mad when running and with ignition on!?

You may consider buying a full version to get all codes decrypted.

Cheers for that bud! So looks like the N75 valve is buggered! Are the N75 valves that come on the cupra the same as the arosa's? As I have a spare one of those!

 

[Theresias]

I doubt the N75's are the same, but a dealer should be able to compare the part numbers.

Had seat look at the motor and they have cleared the codes down and took it for a test drive, they said it was driving fine and the codes didn't come back! Its been 2 days now and the codes still haven't come back so I dunno what happened!?
