Question: 2000 Audi A4 Automatic 110,000 miles. When I try to put gas into my gas tank, the tank acts plugged or something, it wont let me add gas. Is there some sort of valve that's not working? Thank you

Answer: More likely a problem with the venting of the filler neck. Might need to lift and support vehicle to visually inspect the fill hose and the vent.




Question: 
2003 Audi A4 4 cyl Front Wheel Drive Manual 56,000 miles. Hello, I am from Romania and the roads are pretty bad here. Anyway now it's winter and it's really cold and I have noticed an annoying noise coming from the back of my car. I went to a local Audi service and they tuned up my rear seats but the noise is still there. I have to mention that if I have luggage in the trunk the noise stops and also if I have passengers in the back. I don't now what it is but it really irritates me. I would like to know what can be the causes. Please Help!!!

Answer: If this noise is reduced or eliminated with weight over the rear axle, it will be related to the rear suspension, possibly a faulty shock /  strut or a faulty suspension bush, have these check first.



Question:   
2003 Audi A4 6 cyl All Wheel Drive 69,000 miles. I lost my key to my car so I got a copy of a key from an authorized dealer. Proceeded to tow the car to the dealer, called to pick it up later and was then told by the service dept. that I now needed a new control module for the engine as well as a new instrument cluster. A week later, they then said I needed a new Transmission module & as well as another module. A few days later, they now say, they found a nickel (not a dime, nor a quarter) within the cars tip tonic magnets or gears, and that It would cost Three hundred to I guess, remove it. -I 'm sorry, but now I'm laughing..... I only went there to program a good key, that they got for me, after providing my I'D and vehicle title. Please tell me what if any thing, could have gone wrong here. Thanks so much for your time and help!

Answer: Have them do the key work and nothing else. Then take it to another dealership or certified mechanic and see what their opinions are on the matter.



Question: 
2003 Audi A4 4 cyl Wheel Drive Type unknown Automatic 100,000 miles. I have an Audi A4 1.8 Turbo. When it idles for about 3-5 minutes it begins to output blue - black smoke from the twin exhaust. Is this a problems caused by the turbo is not getting air through it when the vehicle is not moving? When driving it does not appears to be a great problem. Alternatively could it be a fuel issue or something more sinister - the rings perhaps?

Answer: This smoke will be oil smoke, I would do an oil consumption test first, change oil and filter make sure oil is exactly on full mark, note mileage and run for one week and check oil, if low add but measure amount used and note mileage. Report back findings, check sparks plug for contamination (oil fouling) is there any smoke (blue) when starting up cold? If not there may be an oil control issue happening, or a turbo oil seal. If a turbo seal is faulty you will see small specks of oil on the back of the car and the tail pipe will be greasy with a little oil as a turbo oil seal leak will not fully burn the oil entering the exhaust.



Question: 
2004 Audi A4 6 cyl All Wheel Drive Automatic 54,000 miles. My windshield washer fluid suddenly stopped working. I filled the reservoir but get no stream for the windshield nor the headlamps. What could this be?

Answer:  Check to make sure there is fluid in the reservoir. The pump may have gone bad and or the fuse for the pump may have blown, also check the line coming off the pump it may be plugged. The switch for the pump may have gone bad. Have someone press the switch and you listen for the pump humming at the reservoir area.



Question: 
2004 Audi A4 Engine Size unknown Wheel Drive Type unknown Automatic 83,000 miles. Hi, I just purchased my car from car auction it has full service history at regular intervals ,very quiet on standing ,however when I took it out yesterday engine noise seems louder as you go faster and then the PRNDS on the display is flashing, it has a tectonic gearbox and revs seem to be running at 2000 can you help?

Answer:  Need to have the power train scanned for codes, but it sounds like the trans is probably having issues. Scan it and get back.



Question: 
1998 a4 2.8 quattro.  My oil temperature light goes on, I checked the oil level and it looks fine, only goes on once in a while, what can it be, I'm thinking maybe a bad oil temperature sender?

Answer: I feel as you do that the oil temp sender may be faulty, before replacing I would make sure that the electrical connection is clean and tight, a fault code scan should give a code for this sensor.
