Bought a 2010 a5 3.2 142k miles. And haven’t gone over 30 mph, but when i start it up it idles fine in park. when i switch it to reverse or drive it violently shakes the whole car coming from the engine. It goes away after about a minute of idling and is smooth. it’s not registered so i couldn’t take it on main road yet, but i decided to do a pull on my street after driving it around the neighborhood a little bit. and after the 3rd acceleration attempt the car started violently shaking again, going about 20mph. tried switching into sport and still shook, and shook while idling after i had pulled over. I shut it off and then about 10 min later started it again and it idled fine, but i’m scared to give it any gas because it may start shaking again. i had 2 misfire codes when i got the car and i put in brand new coil packs, new plugs, new battery and a air filter is on the way. If anyone has had this problem or knows a fix pls lmk. Also got a implausible signal code with a

Trey mate PLEASE replace that pic with one of the car thanks!!!! The problem could be almost anything. My old unloved totally never serviced 3.2 took me from 100k to 200k kms with very very few problems. You need to have the car scanned with VCDS to make a start. DO NOT just start changing things before you have a base line, otherwise you just throw money down the Audi drain!!!!
