    I have a 2003 A4 Cabriolet 3.0 with around 105,000 miles on it. I have this problem periodically that will go away after I put some highway miles on it. The problem usually starts when I am in traffic. I will pull up to a light, the engine will start idling wildly, between 500 and 2500 rpm. Then the Electronic Stabilization Program light will come on. When I start to accelerate from the light, it is as though the transmission won't engage for moment or two and then slams into gear. As I pull up to the next light, as soon as the car goes below 2500 rpm, it stalls and the MIL light comes on. The car starts right up but runs real rough. Replaced the oxygen sensor but not change. Any ideas?

    I have a 2006 A4 Cabriolet with slightly less than 25,000 miles on it since new. At a recent oil and filter change my Audi dealer indicated I should consider having my rear brake pads changed. Their estimates of pad thickness were: fronts 10mm, rears 3mm. I have never had a car where the rear pads wore out before the fronts. This car is driven 'calmly/gently' by primarily my wife and not to my knowledge ever hard braked. Other possibly relevant information on the car: it has its original tires all with excellent tread remaining and uniform across each tire face; no indication of brake drag based on feeling temperature of the wheels and consistently good mpg; brake fluid has been changed per Audi recommendations by Audi; no brake squeal and brake pedal feels normal and stops normally.

    My questions are:
    -have others had their rear pads go well before the fronts?
    -is this possibly an apportionment issue in terms of front to back braking from the master cylinder?

    Thanks! :confuse:

    I have less than 60,000 miles on the car.

    Most of the time, when the engine is started (after idle overnite) the yellow ABS light (and the flashing red BRAKE light) does not comes on ! I can drive a good many miles with no problem. When passing on a 'bump', the ABS light may come on but sometimes it will go off by itself soon after that.

    Usually when light has not been on, when I turn off the engine and restart it, ABS/BRAKE lights comes on.

    I took it to a mechanic who specializes in German cars. The error message on the computer was P1602 (intermittent power supply voltage low). He removed the necessary items to gain access to the controller. He found that the voltage coming into it was a proper 13.7 V.

    He confirmed that the brakes were in excellent shape. When he test drove the car (with the ABS light on) , he found the braking performance to be excellent.

    How serious is this problem from a safety standpoint ?

    On Father's day my audi rumbled (I thought it was a flat tire) and died. I had to restart it several times to pull into a nearby parking lot. It was towed in, "fixed" and returned. A week later, same thing, but this time the dealer wanted to drive the car overnight to make sure it was fixed.
    The next morning I received a call that they didn't get as far the driveway before it happened yet again. As of right now, they are offering to let me out of the lease and into a new audi.
    Any suggestions regarding which ones to avoid?

    Your message couldn't have been more timely. My wife has a '07 A4 Quattro 2.0T automatic with about 53,600 miles on the odometer. Two days ago the yellow warning light for worn brake pads appeared on the instrument panel. According to the Owner's Manual (page 35) it says, "if the (worn brake pads) symbol illuminates, contact your authorized Audi dealer to have the front brake pads inspected (on that occasion have the rear brake pads inspected as well to be safe)."

    This supports the notion that the front brake pads normally wear out faster than the rear ones, so the wear exhibited by your brakes is indeed unusual.

    I'm sorry I can't explain why your rear brakes wore out so prematurely. Did the mechanic offer any possible explanation for this phenomenon? If not, and if it were me, I'd seek another opinion.

    Good luck, and please let us know the outcome on this problem.

    Thanks. I did not think to check the Owner's Manual. Good point. I am in fact checking around with others, especially some Indies this weekend who have experience with foreign car brake systems. I will post what I find.
  • hpmctorquehpmctorque Posts: 4,118
    Good. I think you're following the right procedure.
  • jwdlemjwdlem Posts: 7
    Thanks. So far what I have learned from some Indies is that (a) it is unusual the way the car has been driven for the rears to be showing advanced ware at 25,000 miles (b) it is possible that traction systems have had a play in heavier use of the rears (c) not to worry until the brake ware indicator comes on. To date the brake ware indicator has never illuminated and as mentioned earlier, there is no unusual squeal, shudder, or braking attributes. When I looked at the rear pads I can still see 'reasonable' pad remaining and (at least visually) uniform amounts on both right and left sides. Still interested to see if anyone else has experienced similar ware on the rears but not the fronts.
  • hpmctorquehpmctorque Posts: 4,118
    Yeah, I wouldn't worry, then, until the brake wear indicator comes on. Like you, however, I'd be curious to know why the rear pad are wearing out before the front ones. Could it be that there's some drag on the rear brakes?
  • jwdlemjwdlem Posts: 7
    I am still leaning towards an apportionment issue, but don't think that it is from drag since the rear wheels are not unusually hot when I think to check them and the cars mpg has not shown any drop.

    Welcome to the world of Audi. Typically, common sense tells you the front pads will wear out long before or about the same time as the rear pads. This is due to the front pads performing a large majority of the braking. I have a 2002 A4 Quattro with 75k on the odometer and it is on its 3rd set of rear brake pads. Still have the originals on the front and they still have lots of "meat" on them. Only thing that I have been able to find out is that because the rear brakes are so "tiny" in relation to the front pads that they tend to wear out faster than the front pads as they are providing for a share of the braking but are "undersized" to last very long. Change out is not to bad as long as the rotors still look good and can be done in any home shop in about 1-2 hours including coffee time for about $35-$45 US.

    i have A4 quattro 3.0L 2002 and while i was driving home my front windshield got cracked and it was unreparable. the insurance won't pay for that as the deductable is more than the price of the windshield. my question here is that i can't choose between the original one and the aftermarket so what are the differences between the original and the aftermarket? thanks
  • mercopsmercops Posts: 34
    There are significant quality differences between original equipment manufactured windshields and aftermarket auto glass.
    Main issue is this: Non-OEM auto glass manufacturers make copies of OEM auto glass parts. These copies have to vary slightly from the OEM part due to the fact that OEM parts are patented and the designs are protected and trademarked.

  • hi guys, i need some advice before buying an old Audi A4 B5 1999 with 163,683kms

    what are the issues am i going to face or already facing?
    what sort of problems would it have at most with the year of the and considering the kms over the 12yrs?
    the car is going for $6800, obviously i will negotiate on that.

    one other problem is the car is interstate atm, so i can't my self check it physically and see what the major problems are on it, but i have asked for the seller to send me more pictures on most angles and all receipts done in recent times.

    any warnings and advice would be appreciated.
    cheers =)
  • An old Audi A4 you can't see in person? I already don't like the sound of this one.

    Hello: My opinion? NO WAY! Too many miles, price is out of line, and unless you are a DIY mechanic, you'll end up blowing more money on repairs than you would buying a newer car. The worst part...if you can't actually SEE the car, you're looking for big trouble. If it was super clean, well maintained, repair documentation available, and you could see it, I might consider $4,000 or so for purchase price, but as I said, just my opinion. Good luck! vwdawg
  • I have A4 3.0L 2002. I live in Altoona PA. 5 weeks ago someone hits me in the rear bumper and was looking for an auto body shop who are really good. Money isn't an issue as long as the insurance will pay. So could any one help me in this? Thank you
