2003 Audi A4 Quattro Problems

Fluid Leak From Transmission Output Shaft Seal

A fluid leak may develop from the propeller shaft seal on the rear of the transmission. Our technicians tell us that replacing the seal will commonly correct this concern.

Various Probelms Caused by Clogged Plenum Tray Drain

Clogged drains can allow rainwater to accumulate in the plenum tray (at the base of the windshield). The water may leak into the vehicle's interior, brake booster, or electrical components, which can lead to major problems. Our technicians recommend keeping the tray clear of leaves, pine needles, and other debris.

Maintain fuel quality to avoid misfires and CEL illumination

Fuel quality must be maintained to avoid engine misfire problems; the misfires may cause the Check Engine Light to illuminate.

2003 Audi A4 Quattro Reviews

all 4 wheels just locked up on me while driving down interstate?
My Audi A4 is excellent. It has 92.000 miles and continues in perfect condition. I drove it in Italy for a year and a half (miles a day - 110 - speed 110 to 120 miles per hour. I love my Audi A4 Quattro- is excellent.
I bought my 2003 A4 Audi at 95,000 miles. I bought it with a leak in the rear flange and it needed a new clutch. These 2 repairs together cost $2k My Audi now has 105,000 miles on it and I have not had any other problems with it. I drive it like a grandma shifting between 2500 and 3500 rpms depending on the roads speed limit and weather conditions. I test the acceleration about every 500 miles....
