On my 2011 MK6 2.0 TDI:
My dashboard "coil" warning symbol came on a few weeks ago while I was on a long stretch of dual carriageway, and the car went in to slow mode.
I could keep up with the traffic but no power to overtake anything.
After about 20 miles I got fed up and stopped and after if cooled down it was fine.
Then during the recent MOT and service the garage said it was the EGR. Soon after the coil icon warning light came on again.
So it needs doing.
Garage quoted about £350 for the part and about £450 for labour (or vice versa).
Does anybody know if they can be cleaned, or it is a replacement-only job, and is this a reasonable cost?
(It's a LOT of money!!)
