I have an issue that the glow plug warning light started flashing, will clear if you turn off and restart the engine, it then threw up and EML. Only did it after the car got warm (8 mile) and came on when crawling through stop start traffic.
Had the faults read P0101 and P0236 by VAG specialist, drove the car around as usual for another 2 or 3 days and now the glow plug light comes on every 3rd or 4th journey but on 1 occasion the car went into limp mode I assume as it wouldn't; rev much above 2K. Also I've noted that the car runs lumpy at anything below 1500 rpm and you have to drop into a lower gear but then it's fine.
Garage said first thing to try is for me to do a regen which I've been told to take to for a 15-20 mile drive and keep it at 2000 rpm, does this sound like it could solve the problem or am I looking at something more serious. It hasn't had the emissions fix done, mileage on car is 52000 and it's a 12 plate.
Ideas?
Thanks
