There are 4 owner-reported electrical system complaints for the 2007 Audi A4in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
They have a design defect which allows water to get into the cabin via the moon roof. They also have an electrical motherboard under the drivers feet (comfort control module) that shorts out when it gets wet (which is easy when the rain comes in from the faulty moon roof). Now I cannot un/lock my doors, operate my windows open/closed, etc. And I believe it has negatively effected my ability for brake lights to function properly. This is a widespread issue, not just on mine. They were even class action sued for the same issue with a different year model (and settled out of court, but I was not an owner of the other car year). Please help. Thank you.
OIL LEAKS AND ELECTRIC MALFUCNTIONS AND ENGINE OIL LEAKS...LOTS OF OIL LEAKS EVEN AFTER REPAIRS
AFTER A STOP LIGHT CHANGED TO GREEN I STARTED A LEFT TURN. IMMEDIATELY THE CAR STARTED TO "SHAKE". IT SEEMED LIKE I WAS DRIVING OVER SOME LANE DIVIDER BUMPS. I NOTICED THE ENGINE LIGHT WAS ON SO I FOUND A SAFE PLACE TO PULL OVER. THE CAR HAD TO BE TOWED. THE DEALERSHIP DIAGNOSED A FAULTY IGNITION COIL.( ALL FOUR IGNITION COILS WERE ALREADY REPLACED IN 2010 BECAUSE OF A RECALL). AGAIN I HAD ALL 4 IGNITION COILS REPLACED. I ALSO HAD TO HAVE SPARK PLUGS REPLACED; (POSSIBLY BECAUSE OF THE FAULTY IGNITION COILS RUINING SOME OF THE PLUGS. THE SPARK PLUGS WERE REPLACED ABOUT 20,000 MILES AGO.) I WAS TOLD BY THE DEALERSHIP THAT THE ORIGINAL RECALL OF THE IGNITION COILS DID NOT COVER THIS EVENT. I FEEL THERE SHOULD BE ANOTHER RECALL FOR THE IGNITION COILS AND INCLUDE SPARK PLUG REPLACEMENTS. *TR
WHEN DRIVING MY CAR HAS WHAT IS AND SHOULD BE A RECALL WITH THE GIVEN NUMBER OF COMPLAINTS REGARDING THIS ISSUE OF "RIGHT OR LEFT DIPPED HEADLIGHT." AUDI OF AMERICA IS QUITE AWARE BUT THIS IS NOT JUST ANY RECALL THIS IS A SAFETY CONCERN AND LIKE WINDSHIELD AND AIRBAGS SHOULD BE LOOKED INTO QUITE SERIOUSLY. *TR
