DOESN'T AFFECT THE CAR SAFETY, BUT THIS ISSUE APPEARS TO BE HAPPENING TO A LOT OF AUDI A4 CARS AND I THINK A RECALL SHOULD BE ISSUED TO FIX THIS AS THIS DOES NOT APPEAR TO BE A ONE-OFF ISSUE.
BANG & OLUFSEN TRIM ON FRONT DRIVER'S DOOR IS PEELING OFF AND HAS CUT ME A COUPLE OF TIMES. I TRY AND PUSH IT BACK ONTO THE DOOR, BUT IT KEEPS POPPING OFF. IT IS VERY SHARP. EVENTUALLY, IT BROKE OFF AND I JUST STUCK IT BACK ON THE DOOR.

I RECENTLY PURCHASED MY AUDI A4 AND IMMEDIATELY HAVE HAD ELECTRICAL ISSUES.

I BEGAN TO DRIVE AND THE LIGHT TURNED OFF. AS I DROVE IT BEGAN TO BLINK ON AND OFF THEN FINALLY STAYING ON AND MAKING IT DISTRACTING TO DRIVE.
THERE IS A RECALL ON SOME AUDI FOR THE TRIM ON THE BANG & OLUFSEN SPEAKERS. MINE ARE COMING OFF AS WELL AND ARE VERY SHARP AND CAN INJURE/CUT YOU VERY EASILY.
MY VEHICLE IS LEAKING COOLANT. EVERY 8-10K MILES IT GOES BELOW NORMAL LEVEL IN RESERVOIR . THERE IS A DISTINCT ODOR OF COOLANT EACH TIME I GET OUT OF THE VEHICLE. I HAVE HAD AUDI LOOK AT IT 5 TIMES. THEY CONFIRM THE COOLANT LEVELS ARE LOW AND THEY REFILL IT SAYING THEY CAN'T FIND A LEAK. I AM CONCERN THAT THIS IS A FIRE HAZARD.
PASSENGER AIRBAG GOES ON AND OFF RANDOM WITH OR WITHOUT A PASSENGER. DRIVING ON SIDE ROADS AND HIGHWAYS.
