driving home from work today i noticed that my a6 1.8t was not as responsive as is usually is ...also there seems to be more throw in the shifter than normal ...it was an unusually hot day here in the uk.. anyone?

have u replaced ur spark plugs lately bc im havin the same prob and when the plugs foul out ull lose boost and it will bounce alot. there was someone else that had this same problem

thanks ... a few other peolpe i know have suggested this ...any reconmendation for for a brand . my engine is standard 1.8t

If it was that hot then your turbos were just heatsoaked.
Its normal in that weather

not to mention turbos always put out less power in warm weather due to the air being less dense and having a lot less oxygen...
