I already replaced the catalytic converters,, but the problem continues.

If I drive the car more than 5 miles or 15 minutes, the temp goes way up. Fluid levels are good. Any ideas?

It is a simpler question. How many cats are there on the 2002 Audi A6, 3L

After two or three tries, the car turns over. EPC light still on. Disengage engine, restart and car turns over with no EPC light. Have had a few stalls while driving.

I pressed the gas quickly, it got stuck at 100mph. I stopped the car two feet on brake. Pulled gas pedal to try to release it and it broke into a few pieces. Hanging by a cable. Do I need to buy two parts sensor and pedal? My engine revs up high on its own when I start my car HELP PLEASE ??

It will catch after a few seconds but when it is in first gear it will hardly move once it shifts into 2nd or after going above 20 mph it moves fine. It is an automatic or what I have heard people call it an auto manual.

I have a 2002 quattro 3.0 and I have been trying to track down the source of my reoccurring P0300,301,302,303 misfires... I have tried all the usual suspects... Replaced plugs and coil packs, O2 sensor (even though there was no o2 fault code and now there IS P0140), patched an exhaust leak, replaced breather hoses (found them cracked and broken when I did the o2 sensor), found that the vacuum line was not connected to the fuel pressure regulator so I reconnected it (NO change) I can't pass emissions with my check engine light coming on every time the car warms up (the only reason it goes off is because I clear the code)... Where should I go from here? (with very limited resources)

Runs great except when idling it cuts out and shakes. Any ideas? Also have headlight issue. Headlights will not go down to low beams and high beams work good. Checked several things. Changed out headlights from used car and not sure if that's the reason or if need to try something else or any ideas what to check?

I was driving my 2001 Audi A6 quarto will not start it won't crank or turn over no noise at all but all the dash lights work as normal it all happened when I was driving and I put it in neutral and turned the engine off while still in moving when I tried to start it back up it did nothing I thought it was going to start only cause the dash lights work this is the first time it's ever happened

costing/light braking to a stop and the anti-lock brake fires several times. then all is well. this happens in the summer. how can i fix the issue. The ESP light comes on and dealer will not invest the time to find the issue, just sell a new car

While we were driving down the road, every single gauge/dashboard lighta just shut down like the car was switched off.

My car started running really slow a few weeks ago so i took it to the dealer i bought it from and they told me that it was just a oil leak and that they had fixed it. I payed $250.00 dollars just for that. Now the car stoped running while i was driving to work. I turns on just fine but it doesnt move at all. What could hace caused this?? Someone please explain it to me and how muchos $$ are se talking about?

My car constantly jerks and will not accelerate past 20 mph

Tires and a month later they are saying that my transmission is out. Not sure if it is a good idea to put in a transmission. I put so much money into already? But I hate to lose all of the money I already put into the car.

I didn't want to start replacing parts, crank sensor, etc. until I could pull some codes, but I cannot retrieve information off engine computer.

I accidentally added power steering fluid to brake fluid. How do I flush my brakes?

if i try to idle at 1000 rpm it surges from 2000 to 500 rpm it has emission codes would exhaust leak or emission sensors cause this ?
