Hey - I know there's another thread on this somewhere but it's 2 years old now
So i've got the A4, 57 plate 170bhp version with 83k miles on the clock.
For the past few months i've noticed that i get a bumpy idle however I've been meaning to clean the EGR valve out to see if this will sort it but not got round to it yet. Well actually I did but I ended up getting down to the last bolt on the EGR and stripping it!!
Anyway - about a month ago on the motorway I got a flashing light which looks like a coil but apparently is the glow plug light? Also went into limp mode. I had a quick google while I turned my car off and read that it could be related to a wet footwell, esp if it's raining. It was raining so I put it down to that. It hadn't done it again until last week when I've been commuting home from work, 3 nights in a row, on a slight incline on the M74. No rain to blame either!
I've yet to get this scanned for faults but can anyone from experience tell me what the possible fault could be?
Also when sitting idle at traffic lights, I can smell a strong fuel smell coming from my car. Excess smoke I think - but i'm not sure if that's related.
The car has had the injectors replaced under recall too.
