Hi
DPF light been coming on quite frequently, it does regeneration ok. Few months ago engine management light came on, took into Audi specialist who said needed new turbo as probably coked up. Had new one fitted. Went back few weeks later as still had the engine smell inside, was advised needed dpf sorting. Stupid money. I then took it to my local garage who said the only thing he could find was the bolts on dpf filter were corroded and he thought was leaking slightly... He drilled out the bolts and replaced.
Still no better, done couple thousand miles since but when ticking over it's horrible, any ideas would be appreciated.....Mark
