2006 Audi A4 Quattro Problems

Check Engine Light and/or Hesitation Due to Failed High Pressure Fuel Pump

2.0L turbo charged engines may develop a hesitation on acceleration and/or illumination of the Check Engine Light due to a failed high pressure fuel pump or a worn camshaft follower or camshaft. Our technicians tell us that whenever the high pressure fuel pump is replaced the camshaft and the follower should be checked for wear. The camshaft lobe pushes on the follower to operate the high pressure fuel pump. Frequent oil changes and use of synthetic oil may help with this wear issue.

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.

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.

I bought my 2006 brand new. Didn't have a problem until I reached 75,000 miles. Now I have an oil leak, my left engine mount is leaking, and my left bushing is cracked. I am wondering if this is just the first of major repair bills, do I fix it, or do I get rid of it. Of all the cars I have had both new and used with miles up to 150,000 I have never had an oil leak. And by the way, the oth...
49000 miles the engine is gone, than the camshaft . Do not buy this as a used car. They do not lost. The mileage is bad, road holding is soso
I love this car. It's the perfect size for city driving (parallel parking is a breeze) and the 4WD takes you to Tahoe in most any conditions. Living in San Francisco, the Quattro is a must - it gives me an extra sense of security on those many rainy days. I opted for the 3.2, 6 cylinder option which gets me on the freeway (and up mountain roads) in no time. I have developed an addiction to ...
