Audi A4 Quattro Problems
Check Engine Light Due to Vacuum Leaks, Oxygen Sensor, or Catalytic Converter Fault
Vacuum leaks, oxygen sensor failure, and catalytic converter efficiency faults can cause the Check Engine Light to illuminate.
Inspect CV Boots and Joints at Each Service
Our technicians recommend having the constant velocity (CV) boots and CV joints inspected at each service. Servicing torn CV boots early can prevent the need to replace the CV half shaft or CV joint.
Flasher Relay Failure Can Cause Erratic Turn Signal Operation
Erratic turn signal operation can be a result of a failing turn signal flasher relay which will require replacement.
Multi-Link Suspension Components May Wear Prematurely
Premature wear in various multi-link suspension components can cause noises that are difficult to diagnose. Worn suspension parts can also cause uneven tire wear and create steering alignment problems.

All lights come on but none stay on. Will start back up after a couple of seconds. Also if car sits in neutral it will just stop. Would the cold weather have anything to do with it.

Audi A4 Quattro Stories
Hi, i was just wondering where i could find a Mass air flow sensor for my 1999 audi a4 quattro for a decent/cheaper price? It needs a new one because its making a clunking noise and it shakes when it does it, and after that i have absolutely no power in my car. You can email me at kutless11@hotmail.com, or just respond on this. Thanks.
Just got this car a month ago. Car seemed to run well however there was a little squeaky noise when accelerated on first and second gears. It stopped as i drove it more. Check engine light come on and off. Now the oil light cam up, added oil and its still on. Havent driven it (this just happened this weekend). As i tried to drive it to get it checked it started a rattly noise coming from underneath the engine, I dont know much about cars but this noise doesnt sound good. sounds like something grinds, almost as if the gear was stuck. It stops once you get to 3rd gear, but will come back as you slow down. It starts as soon as you start the car. Shifting gears are smooth and car starts normal, its just the going that seems to get the noise out the most. If you know what this could be let me know. bigiulgonzalez@gmail.com

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 other cars were all American made.
Anonymous the oil pressure problem you are expeirencing is due to sludge if you followed the manufacturers recomended oil change intervals at 10000 miles you are in trouble the dealer is well auare of the problem they are stringing you along so they are not liable it is a process and maintance intervals have to be veriphyed that you used the proper oil and filters to get any warenty on this problem look up low oil pressure problems audi a4 1.8t you will see what i mean I have actualy removed the engine out of my a4 to clean the block and install a new oil pickup screen in the engine the continued running of this engine in your situation will take out your turbo if it hasen"t already and then your cam bearings will get tight and take out the timing belt so good luck and do not run it if you can avoid it you will need a very good mechanic to work on this situation not a shade tree very tempermental engine
