CALL AUDI COPORATE. THEY HAVE OVER A MILLION COMPLAINTS ABOUT THE A4 MODEL. THE ENGINE HAS A BAD SEAL PROBLEM. IF YOU SEE WHITE SMOKE COMING OUT OF THE TAILPIPE TAKE IT STRAIGHT TO THE DEALER. TELL THEM THAT YOU ARE AWARE OF A 'MANUFACTURER'S DEFECT WITH THE A4 ENGINE AND THEY WIL FIX IT FOR FREE. I HAD AN A4 WHICH IS HOW I KNOW. THANKS !!!!

Check the air intake and make sure no wash rags were stuck in there. It is slow in acceleration? could the car been damaged underneath? Squashed exhaust pipe or catalytic converter pinched? you need gas, electrical spark, and air to run the car. The computers try the best to make sure the correct mixture is applied to have the engine run at peak performance and have good emissions. If it is not getting enough air, or can't rid itself of air, that can cause power loss and set off a lot of signals. Have the computer read and see what the triangle with the exclamation is telling you.
