2006 Audi A3 T2.0 Sport check engine light?
i drive a 2006 Audi A3 t2.0 sport package vehicle. it has 150k miles on it, an automatic
transmission and it still runs fairly well. just recently my check engine light has come
on. the local shop doesnt have a scan tool (to check codes) that fits german models. the
nearest town is quite a ways away. anyway, here are the symptoms. Everything is fine until
i hit about 40 on the highway. At 40 mph the engine starts to take on a much louder, almost
rev like sound. but the sound fades away and becomes inaudible at around 60 mph. when in
drive the transmission has already shifted to 5th gear on its own by the time i hit 40mph.
i have yet to try driving in sport mode since ive noticed the sound. please help?
