Hi all, I bought my already remapped 2.7 TDI A6 in December however the engine management light comes on fairly regularly and far to often, every few days, the glow plug light comes on and puts the car into limp mode. This mainly happens when in 6th gear and pushing the car uphill but recently it has started happening a few miles down the motorway on cruise control. The error code is picking up a boost error so i assume it is something to do with the remap and I need to book it in with my local VAG place to check that out. The other day though, I was in a car behind with someone else driving my car and I noticed how much the car stunk and the amount of black smoke from the exhaust. Going to do an oil, fuel and air filter change and see what that does, anyone got any other comments? Also, anyone put a non standard, pipercross or K&N, panel filter in? Have you seen any difference from the standard?
