This is my first post on the forum, I'm hoping someone can provide any information, so here goes.
We have a Golf Mk6 S 1.6 TDi 105PS, and have had it since Dec 2009. It's done about 8,000 miles.
From the first few months of delivery, the DPF light came on, but after a 'vigorous' drive on the motorway it cleared the problem. When the light is on the idle is lumpy and the car vibrates ever so slightly, which I take to mean that the carbon deposits are blocking something in the exhaust and the engine management gets confused? Apologies, I'm not 100% au fait with diesel engines and the way they operate (mk1 GTi and ex-mk4 anniversary gti owner here).
Last weekend the light came on again, and after a while, the coil light started flashing. There was no turbo response and it seemed like it was in some sort of limp-home mode. Then the engine management light came on.
I haven't driven it since this came on, and have booked it in to be looked at tomorrow. Is there a problem with the coils on the TDI? I am hoping that it's a simple fix, and covered under warranty.
If anybody could shed any light on what this could be it would be most appreciated.
