hi i am a bimmer guy. so i bought an 2002 audi a4 3.0. i thought all audis are 4wheel drive turne out this one is not. my misstake. but any ways. car has a 205000 miles but looks good and clean. here is the problem
when its cold its fine but when its worms up after 15 min of driving when stoped at athe light or stop sign the car jerks when its in thw first gear its automatic. like if its some one rear ended me.
on the audi display its displaying a yellow oil sencor icon?
and two codes even though i passed immisions p0421 and p0431.
like i said i am not an audi guy so i have no clue maybe one of u had simmilar experiance. i dont want to take it to a dealer i can bolt on bolt off my self if i know wht to do. just asking for your opinion. thanks any suggestion will help. ps i just bought this audi it 3 days ago and i cant returnt it

 

welcome and for one your oil sensor is out and will need replacing. The other two codes are for cats i think. A common failure in our audis.
