Just bought a high milage*1999*a8*Quattro, a mint example minus an oil leak....... and the abs ligh........and the airbag light that just appeared.

And now this this morning i noticed when i put it in reverse it didnt have that pull so when you release the brakes it moves but that went away immediately. And i just got home after a 45 min round trip and it just clunks at a stop light and all the gears light up and it feels like its in a higher gear(limp mode??). And a check engine light appears.
If i turn the car off it will work until i give it some gas and clunk same thing.
These are the codes i get.
