Hey guys. 2003 S3 BAM Had a few problems this week with my car with boost. The car seems to have less power and the boost isn't smooth, coming in and out fairly randomly. Anyway, I had an inspection under the bonnet and found a split in the intake hose where it branches off up to the pressure relief valve. The joining pipe has also gone lame (rubber been getting too warm). Anyway, over the weekend I had removed the whole intake pipe assembly, and attempted a repair on the split. I cleaned out the relief valve and renewed the adjoining pipe. Before I order the replacement parts from Audi, I wanted to tap into your knowledge base for some help/suggestions. I have the engine management light on the dash, and took it to a friend with VAGCOM to see if we could clear it. I got three faults. 16497 - Intake Temp sensor G42 signal too high 17864 - Exhaust gas temp control bank 1 limit attained P1456 intermittent 16716 - Knock sensor 2-G66 signal too low P0332 So ok, I had a look at the intake pipe again, and I think Im right in guessing the intake temp sensor is on a small T piece, branching off from the top of the intake pipe. Also, my logic is saying that if the air is being read as too hot, then the car will run lean and thus affect the exhaust gas signal ?? Also, with these in mind, could the knock sensor be due to the engine not running smoothly as a result ? Anyway, hopefully someone will know what Im rambling on about. Id appreciate any info or suggestions as to what I can do as the next step or just any help in general. Thanks in advance.
