#1678 of 2367 A4 2.0 reliability
Dec 08, 2007 (9:35 pm)
I have read a fair amount of negative comments about these cars, but most relate to older models. What problems have you had with 2006-08 models? Is the 2.0 better or worse than the 6 cylinder? I would be replacing a 2001 Saab convertible. That car has been good, albeit with a few more problems than I would have liked -- but nothing like the horror stories some have related about the A4. I need a reliable daily driver convertible with enough trunk room for golf clubs, beach stuff, etc. The A4 appears to be one of the best available for my space requirements, but I believe a modern car should easily go to 100K miles with little or no unscheduled maintenance. Can I expect that a new Audi to do that? Are there issues specific to the convertible?

The car calls for 91 at the least and it will run on regular but at reduced performance and mileage. Any savings realized by using the lesser octane is lost in reduced mileage so your not really saving anything.
Assuming the car is now running well and rough idle is gone you can expect that engine light to go off after a few start/stop cycles. If not then you need to pull the codes.
I recommend that you use the gas this vehicle calls for to realize the full potential of that engine. it will has knock sensors to compensate for lower grade gas but it's really a false economy as I have said above.

Disaster: drove the car about 50 miles today to burn off some of the regular gas. Stopped, grabbed a coffee and went for a 10 minute walk. When I got back to the car and tried to start it, it wouldn't start! Tried starting 4 times, nothing. Ended up getting it towed to my local Audi dealer. Hopefully nothing too serious is wrong (they reopen tomorrow), but a new car with only 14,000 miles shouldn't just NOT work because regular gas was put in the tank?? Beginning to have some serious doubts already about purchasing this Audi 2 weeks ago....

I've heard of fuel filters clogging within 15k miles.
If that turns out to be the problem, I'd be careful where I buy gas.

Interesting....so this could be a cascade-type problem: lower octane fuel means I get the misfire and then also the fact that it could be crappy gas in the first place means the filter gets clogged, causing the car to not start anymore.
If this turns out the be the case then I will be VERY careful about where I get my gas!
#1683 of 2367 Audi A4 headlight problems
Dec 13, 2007 (11:25 am)
I have a 96 audi a4 quattro and the headlights are not working. Its not the fuse and its not the bulbs i think it might be a relay switch some where. When i turn the lights on the running lights come on but the headlights do not. Just wondering if any one had any advice on this situation.

Could be your headlight switch. Is it a stalk type? You might be able to sneak it out of the steering column (or dash if that's where it is) and bypass it to see if that lights up the headlights.

I had this similar problem and it is the little spring-flap inside the Audi fill-pipe that blocks the gas from going-in. You need to really push the gas filler deep into the pipe so as to ensure the little spring-flap is held open and not blocking any gas flow.
Good luck - james

Happy to say that I called the dealer back & asked that the mirror switch be replaced under warranty. He complied with no fuss.
#1687 of 2367 Noise from rear axle.
Dec 22, 2007 (12:18 pm)
I have a 1996 N Audi A4 Quattro and there is a bearing/diff noise coming from the back of the car. Afriend has also got this, he changed his diff with no luck.
I'm hoping somebody knows of a common fault?? My suspicions were wheel bearing, however the previous owner changed them only 2 years ago.
