I just got a 2006 audi s4 and drove it from CALI to SC. On the way home the car started to have some performance issues. At first, it wouldnt want to go over 5k rpms and would hesitate really badly when you pushed the gas WOT. When i got closer to home it got worse and would hesitate at even half throttle and the check engine light blinks then just stays on after. Im thinking its coil packs and/or spark plugs. Anybody else have any suggestions?
I tried to check it with my dad's vag-com but its for his 04 S4 and when i checked the site (ross tech vag site), it says his wont work for mine. He has a HEX, KEY/KII and i need a HEX+CAN interface
