Hi All!
First post so go easy on me There's a bit of a story to this one so please bear with me, but it relates to the check engine light coming on but the diagnostics check not finding any error codes.
Back in April, my check engine light came on and the code suggested an issue with the accelerator sensor. I was told it could be 6 days-6 months before it needed replacing, and sure enough, 4 months later, the light came on again.
I was on a long motorway drove so pulled over, turned the engine on and off a few times to clear the light, and carried on. The light came on again about 20 mins later, so I did the same again. On both ocassions I was driving in excess of 65mph.
I did the rest of the long drive home at under 60mph and didn't see anything then for a couple of weeks.
The light came on again after driving approx half an hour at approx 70mph. I cleared it, but it came on again (twice) so I resorted to getting RAC out and they found 2 codes - one was the throttle sensor, the other unknown. I got it to my usual garage, they replaced the pedal and cleared the faults.
A week later - again, after driving approx 20-30 minutes and at 65-70mph the light came on again. I cleared it, then the same happened on the return journey after driving about 45 minutes at 60mph. So, I got it back to the garage but they couldn't find a record of the light coming on/there were no codes stored. This is where I need your help guys!
Why would this happen? What could it be? Could it be the 'unknown' error code from a couple of weeks ago? Something completely different? The car 're-learning' (I've read about this but in all honesty, don't fully understand it).
Bizarrely, a colleague had the same thing happen with his Fiat 500X - the light had come on (unsure about length of drive or speed). It went off of it's own accord, then when taken to the garage, there was no record of a fault.
I am now feeling totally anxious when driving, daren't go any speed or distance, and subsequently spending a fortune on public transport, so any suggestions that you lovely lot could give me would be hugely appreciated!
