Engine Performance problem
2002 Audi Quattro 6 cyl All Wheel Drive Automatic 128000 miles
I have an A6 3.0 Quattro Audi and my car doesn't drive the way it used to. I have spent thousands of dollars trying to fix the issue and NO mechanic can find what is wrong with it. I can be driving and all of a sudden the ESP light will come on and when I stop at a light, or stop sign or slow down below 15mph my car rpm's go down to 0, then the battery light comes on and my car shuts off. I have to put it in park then restart my car and accelerate then my car chokes and sometimes reverses a little then goes forward, but if the lights still on it will stall when I stop again. If that light is on and I'm on the highway going over 50mph for like 15mins the light goes out and my car won't stall it's only when that light is on. I have replaced my MAF sensor, my timing, Just replaced my catalytic converters yesterday which was what the codes were saying. Yet TODAY my car stalled again 6 times. It's very frustrating! I've heard so many different possibilities. What could it be, this is what I have in mind: Camshaft sensor, O2 sensors, Airflow Mass Meter, Clogged intake port, clean water drains? I don't know what else. Please someone has this happened to you? It's that little light w/ a triangle and exclamation point in center w/ an arrow around it. It's frustrating as this has been going on for over 4yrs with thousands of dollars and multiple mechanics even AUDI Specialist. Any ideas?
