    Replacement or repair?
    The PRNDL is flashing and reverse not working. The fault code is 1793 . It would be very helpful to know, did the problem get worse without replacing

      From what I briefly researched online, it is simply a code that means you need to reformat your transmission control module. Other than making sure the fluid is at the proper levek, you should be ok. But don't take my word for it, take it to a transmission shop

      You can find used auto parts for your Audi at the local parts stores and auto dealers. Another option is buying from an online auto parts store.
      If you want to get a car part replacement very quickly and use it immediately, do take a little time to go to aftermarket and pick the right one for your car. There are numerous auto parts suppliers online which offer customers convenience. You can buy used parts from which are of high quality and at an affordable price.

      Yeah I agree with hock and suggest you to try at your nearest junkyard and if you're unable to find your stuff there, check out an online auto parts store called . I personally prefer to purchase parts for my Audi A3 from their only, however you could find component of every model of nearly every car. Give them a try as well.

      I think buying from auto parts online stores is a great way of locating your required component at decent prices. However, it is true that junkyards are the cheapest place but online stores provide your stuff with warranty and it makes them quite reliable. I want you to look at for purchasing required components of your Audi.

    Lost power to all 4 wheels in all gears.
    Hi, I had an issue with my 2000 Audi TT Quattro Base 4 Cyl 1.8L. I stopped and lost power to all 4 wheels in all gears. I shut off the car and when I restarted it I have power to rear wheels only. Anyone have any idea what would cause this problem. Thanks, Don.

    Worn out clutch after 10 miles, 2 years!
    My wife has driven manual transmission cars for years, probably over 100k miles without a problem. The engine was revving at odd times so she took it to dealer Audi claims a clutch is a wear and maintenance item. Somehow she wore out the clutch. We had to have ...

      Have the vehicle and clutch condition thoroughly inspected at a trusted, local independent shop in your area.
      Be sure to get a detailed written report and itemized estimate from this other source.

      Take the written report and estimate to the dealership for their response - without having an on-hand and personal inspection - it's difficult to assess the next step for you.

      The third party inspection will help you determine the correct path and decisions in this regard.
      11/28/2014 Driver101
      Thank you for your answer. Could you tell me though, and I have limited knowledge of mechanical things, wouldn't the clutch show it is worn out even if it was a mechanical fault. Couldn't it have been something the dealer adjusted when they removed the clutch assembly...for example replaced a spring, lubricated a part, replaced a part, tightened a screw?

      I am willing to take the part to an indie garage, just wondering if it can really tell who is responsible.

    • Jimm
      11/28/2014 Jimm
      Given the limitations expiring, have you considered going beyond the dealership to the company levels?

      You miss the point - the purpose for the independent inspection is not to assess responsibility for the worn clutch, but to honestly report the condition in a written form. Bottom line, there is no way a 2013 model year vehicle should have a worn clutch is only 10k miles and 2 years old..

      Then you can take this detail to the dealership and request their response / recompense / to make the clutch right - at their expense - as an attempt to retain (hopefully) your business. If the dealership is smart or business-savvy, they should recognize this opportunity before them.

      By the way,as far as an adjustment for the clutch - the system is hydraulic; (components with clutch master and slave cylinder) - with no adjustment possible for life of the clutch disk rotating mass.

      The car went back to the dealer because the engine was revving. The cost of the repair would have been $2400. I believe the dealer knows we didn't cause the problem, so they did what they could do. They discounted parts 50% and labor 10% and the bill was reduced to $1650. They tried to get more from Audi Canada but Audi head office won't be's wear and tear and they won't budge.
      The dealer has been very fair but is blocked by head office. THX for info about the clutch mechanism.
      11/30/2014 Driver101
      JImm, I reread your answer and there is lots of good information for me there. 1) I see the importance of an independent report from a mechanic, that would be helpful if the problem goes to arbitration (if Audi doesn't pay at least half of the repair cost), 2) it seems you don't think a clutch should fail at 10k miles, and 3) your explanation of how a clutch assembly works.
      I appreciate your comments.
      12/1/2014 Driver101
      Jimm, thanks again for your replies. Using your information I wrote to the president of Audi Canada and they will reimburse me $500 for the repair. Original cost was $2350, with dealer deductions, $1650, and with this $1150. I am OK with that. Appreciate the help. Driver101

    My Audi is in the shop possibly needing a transmission replacement. Advantages/disadvantages of Used vs rebuilt or new?
    While I was traveling, my car was hesitating some at corners. Later on my oil light came on, (a little low) so I had an oil change at a service station. (He put in 6 1/2 quarts of synthetic oil and new filter for $145). I drove the car for approximately two hours ...
    • Jimm
      11/1/2014 Jimm
      Wow -$145.00 for new oil and filter change! As far as the transmission - get the best warranty possible (if you plan to keep the vehicle) which is typically 3 years /36k miles if rebuilt or remanufactured.

      Check these various on-line vendors;,,, to list only a few. For example, they (RockAuto) list the remanufactured transmission from around $4643.00 (minus core exchange and installation labor) for your vehicle.

      For sources of used transmissions,try these vendors;, - to list only two possibilities.

    This is a Front Wheel Drive car. Should I replace the whole axel at approx100.00 parts cost?
    • Jimm
      5/23/2013 Jimm
      The cost of the front axle seal itself is inexpensive when compared to the labor. You can find the axle seal from around $2.50 to $5.00 at the many on-line auto parts sources, such as;,, - to list only three.

      You may expect to pay around one hour labor for the seal replacement - typically from $70.00 to $100.00 per labor hour - depending of the repair shop charges.

      Audi has issued a Technical Service Bulletin (TSB) 38 07 01 dated: Jan 9, 2007, 2013280/1.

      Seems to be very common issue with the Audi CVT transmission - lots of information on the internet in regard.

      No drive or delayed drive in "D" or "R" (DTC P1743/18151 may be stored in TCM)

      No drive, or delayed drive when either D or R is selected. DTC P1743/18151 may be logged in TCM fault
      The vehicle does not start moving without accelerating. When accelerating, an increased engine speed is
      necessary to move the vehicle. In some cases there is no drive.

      Technical Background:
      Some damaged seals installed in production.
      The damaged seals may leak after a short operating period (less than 13,000 miles), causing a loss of
      transmission oil pressure.
      This condition will not result in unintentional vehicle movement.

      It is not necessary to receive an authorization number from the Technical Assistance Center for the repair
      described in this bulletin.
      Attach VAS scan tool printouts to the repair order. Warranty requested documents received without VAS scan tool
      printouts will be denied payment.
      If fault P1743/18151 (clutch slip monitoring signal too large) is stored in the transmission fault memory, read MVB
      44/1 and 45/1. If MVB 44/1 is 1000 mA and MVB 45/1 is above 12 bar, there is a problem with the axial seals. If
      MVB 45/1 is below 12 bar, this indicates a hydraulic problem.

      Check with the local dealerships for more detail on the TSB and if there is any warranty action as result of the production-related defect as described in the TSB.
