you likely have a sludge problem. check into the lemon laws in your state.

 

i bought the car used with 113k and from a different state.

are these cars known for sludge problems?

 

not so much sludge but they do suffer oil pump strainer blockage due to poor maintenance and using cheap oil and parts

 

A reason for haveing a carchecked by a mechanic before you buy.

If you bought it from an individual, you are likely SOL/ If you bought it from a car dealer, you may have some recourse

 

the motor is not seized.
the motor does turn over but due to the CPS code it will not start.

im a technician myself, i checked the whole car over before i bought and drove it for a good 20-30 minutes.

 

how would you guys go about taking car of a sludge problem?

 

Take the oil pressure sender out of the back of the oil filter housing and check the oil pressure, if its low take off the valve cover and pull a few cam caps off and check the bearing wear. If its not too severe, take off the oil pan and change the oil pick up tube. If its bad and stalling on you, then you might need a new engine mate. Audi will cover the repair if you can show proof of oil change reciepts.

 

im pretty sure the car stalled because of the CPS. only 1 of the 2 bolts that hold it on were present

 

I don't mean to nit pick but what the hell is a CPS?
