    I just purchased a 1998 A4, rack and pinion is leaking and needs to be replaced. I have called a few audi parts departments and am told it could be one of two racks. Short of having someone pull it out, how can I determine which rack and pinion I need. Can't afford to have it done at a dealership.
    1998 A4 2.8 Quattro 30v V6.
    How often does the oil need to be changed?

    Thanks

    Do I need to use premium gas in the 1998 A4 2.8 V4?

    Thanks

    Hi All: I had my A4 idling in the garage last week and was shocked to see a fine spray of fuel shooting out from the underside of the chassis. Visualizing both my beloved car AND my garage exploding in a ball of flame, I shut it off, jacked it up and inspected, finding that the the rubber portion of the fuel line, just aft of the fuel filter, had deteriorated and was leaking. The rubber portion leads to a metal fitting which is connected to what looks like a plastic section that runs up to the topside of the filter. Fine, I said, I'll just pull the filter, and replace it and the bad fuel line unit at the same time. My manual says "Loosen the lower banjo bolt, then LOOSEN THE CLAMP BOLT, pull the filter down and then loosen the upper banjo bolt". After loosening the lower banjo, I shined my light up into the filter area and was shocked to see that the "clamp bolt" appears to be almost impossibly inaccessible. It has a cylindrical head, which looks like a hex bolt, but since it
    faces horizontally, I can't even verify that. There is NO space to get a hex wrench in there. My conclusion is that either there is a special tool, a special technique, or this is :mad: one of the worst examples of German engineering I have ever seen. Can anyone tell me how to loosen that clamp bolt and get the fuel filter dislodged from its cozy little space? Thanks! audiphile1 in St. Paul.

    I think there is a rear axle cover you have to remove.

    Thanks, Mr. S...I didn't see any type of cover. The filter itself is readily accessible, well ahead of the axle. The problem is that the "clamp bolt", which is higher up in the cavity where the filter is located, is very tough to reach. Looks like an "Allen"/hex-type bolt, but there is very little space in which to insert an Allen wrench. It almost looks like the filter was installed before the fuel tank was put in at the time the car was manufactured. I'm puzzled as to how to get that dang bolt loosened. Anyone have a suggestion? Thanks...audiphile1

    Weird. The book says it only takes .4 of one hour to swap it out. Maybe they did make a mistake in installation.

    Are you on a lift or just crawling underneath?

    This is crazy. The dealer is SUPPOSED to know this, because they have the files that identify the gear by VIN #. How are we supposed to know if THEY don't?

    Seems to be a difference in the manufacturer of the rack.One is ZF the other is KOYO.

    Maybe you can read something off the rack. Also one parts catalog mentioned that the ZF has a "one piece aluminum casting" if that helps.

    CHECK IT OUT

    To get to the fuel filter/line;there is a circular access "hole" somewhere under the back seat on the passenger side.Just pull out all the fancy carpeting to expose it. Yeah Audis no have 80% "recycelable parts which degenerates over time. :mad:
  • tgai69tgai69 Posts: 7
    A4 has a "bigillion" airbags...culprit could be as simple as loose contacts (under the seat) to bad sensors(in the bumper).Audi dealers(ripoffs) have the right VGA tools to decode the fault....and hopefully free estimates! ;)

    Just bought a 1997 Audi A4 1.8 Turbo. Sometimes the engine won't start. The starter is new and it is good. The battery is good and the cables are connected properly.

    Sometimes when it doesn't start, I will get out of the car and reach in through the window to turn the key and it will start.

    Is there some kind of sensor in the seat?

    The mechanic thought it might something between the battery and the starter? He checked the battery (even put larger cables) and he took the starter out and checked it.

    Help!

    Thanks much. What about the gas? Should I put premium in? With the synthetic oil, how often does it need to be changed?

    Thanks again...
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 45,064
    Whatever it says on the gas cap is the grade you should use. Synthetic oil should be changed according to an oil analysis, but I'd say if you wanted to play it super SUPER safe, without getting the oil analyzed, 5,000 to 7500 mile intervals.

    Hi, I have a 1 month old 2009 Audi A4 2.0T Premium Plus Frontrack with 1300 miles on it. Today while driving back from work, the car stopped at a 'Stop' sign and in 'D' mode, wouldn't move anymore. I had other cars right behind me so without panicking I shifted down to 'S' mode but it remained the same. I then shifted down to 'M' mode but it still won't move at all. Then I shifted back to 'D' and gave it a lot of gas, all of a sudden the car started moving but extremely slowly enough for me to pull into a small street. I pulled over, stopped the car and re-started it. No problems in starting back however when I put the car in 'D' the same issue, it would barely move. Then after a couple of more tries the car came back to life. I kept my fingers crossed and drove a couple of miles home. I am heading out of country on Friday and I want to have the dealer look at it after I get back. Does anyone have any suggestions or have experienced anything similar? Much appreciated.

    The dealer will need to perform a diagnostic test to see what happened.
    I have a 2005+ A4 with the 1.8 engine and started having slippage between the D and S modes while driving. The dealer needed to replace a computer module related to the transmission - what they called the brains of the transmission. It was done under warranty and I was told this item is under a CA emissions warranty for up to 7 years from when I bought it.

    I need help. My transmission needs replacement. I have am the original owner and have maintained the car, more so than anyone else I know. The car was wonderful for 5 1/2 years and the last six months have been hell. Since then, all four coils and plugs have been replaced, the coils, one by one going bad. I've had the rack and pinion replaced, the motor mount replaced and now the transmission. I now have read everything about the CVT problems with the early 2000 models and am scared to death. It is culpable to know that Audi has known of these problems for years and done nothing. I was also told at the dealer that they have been fighting the coil problems for four years. I do not know what kind of recourse I have nor do I understand what the dealer might be doing to try to "help" me. My contact is calling me back tomorrow after his district manager gets back to him on an email he sent him explaining my situation and seeing if they can help. What does that mean exactly? I called cust. svc this morning and they too indicated that there may be some kind of "help" but that I would have to take the car into the dealer as a first step. I have one more car payment on the car and absolutely love the car and everything up until the last six months. I appreciate your advice in advance.

    Help! My son had to have the fuel pump replaced in his Audi A4. When he picked it up, as he drove down the street he realized something was wrong and returned to the mechanic. He left the intake exhaust off disconnected. The mechanic reconnected the hose. The next day when gas was added to the car, the check engine light came on. This car has gone back to the shop 5 times and the mechanic cannot figure out why the check engine light is coming on. The code is something about the Turbo.

    Can you help? Did the mechanic do something when he left the intake exhaust off?

    Not sure what you're talking about here. The terms you are using don't really identify the part very well. Do you have the # of the code that was read? That would help us a lot.

    Hi tgai69: Thanks for the reply. In a state of desperation, I already had removed the back seat, thinking maybe there was an access port (or maybe I could even cut my own access in the sheet metal with a hole saw). I couldn't find any sort of cover. Eventually, I customized the proper size hex wrench (ground the short end down to about 3/8 inch) and was able to get it up inside the fuel filter cavity. After installing the new one, and rather than spend another hour trying to tighten the hex bolt, I just installed a large hose clamp around the filter and bracket, which seems to be a much easier solution. Someone else stated that the flat rate on this job is .4 hours, which seems reasonable. Took me more like four...one of the most frutrating Audi repairs I have ever done! Thanks again. audiphile1

    hi i wondered if someone could assist me. When i turn the key in my audi A4 SE the car will start ticking over and then just cut out. Now i turn key off and on again and same thing happens. If i carry on doing this it finally starts sometimes 1st time sometimes 10th time. Once car starts it runs beautifully. Please help me.
    thankyou

    Sounds like a faulty fuel pressure regulator that is bleeding off pressure in the fuel rail---so, without fuel pressure in the rail, the fuel pump must pump away to renew enough fuel pressure to keep the car going after every shut down/leak down.

    Sorry to hassel you sir but thanks alot for the reply. Is this a job for a mechanic or can i sort this out myself? Will this be expensive?
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 45,064
    Well you can really test the regulator without a proper gauge and a workshop manual, so probably you should bring it in, yeah. Maybe a $200 job if my wild-[non-permissible content removed] guess is correct.

    The gauge allows you to run the engine, test the pressure (about 4 bar) and then see how much bleeds off in 10 minutes. It should drop to 2.5 bar. If it goes lower, I'd suspect the regulator is faulty.

  • Hi everyone - my Audi is 5 years old. I put the convertable top down the other day and when I put it back up I noticed that the rear window was no long attached...leaving a space all the way around (between the fabric and the window). The Audi dealership just informed me that the space can not be glued or repaired and that I will need to purchase a whole new top. Cost? Over $4,000.00! Have you heard of this happening before? As much as I love my Audi, I think it's pretty shoddy craftsmanship if the top needs to be replaced after only 5 years... Would love to hear your suggestions, feedback.
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 45,064
    You might get a second opinion about all this from a first class upholstery shop in your area. The book says only 6 hours labor so even at $150 an hour that's only $900. Since when does cloth cost $3100 bucks?

    Here's one for $1495....so add that to $900 and that's sounds about right

    AUDI A4 TOP

    I'm not recommending these people, just using them as an example.

    Average age of a convertible top is about 10 years, so yeah, it's premature, but convertible tops lead a hard life, so.....

    I just got my last "free" maintenance done the other day and they replaced the front brake pads and fixed the worn rotors: "front brake disc remove+reinstall" and "wheel remove+reinstall".
    2 days later (today) my car ('05 A4 2.0T) is making a very strange noise when slowing down, especially on an incline and then accelerating after the green light regardless of the grade. Problem is that this noise comes and goes. I have 34,000 miles on it and I'm scheduled to have it checked out Monday. I'm not a mechanic by a long shot. Does anyone know what this may be? Many thanks in advance!!

    Ok well It's Been A few thousand Miles later Im up to about 18,000 Miles Been Driving on the "Recomended" Gas for a long time now, and I still have oily slimy soot in both exhaust Tips. Can't keep em clean. This can't be normal. Even though the Dealer says this is normal. It's B.S. I don't trust em! This is a NEW Car! This NEVER happend to my three previous new cars which were Acura: Integra, RSX, and RSX TypeS.

    Also is now burning a full quart of oil just 4,000 miles after my last oil change.
