  1. This concerns a post about Audi 7:
    Never owned an Audi product by VW. Irrespective, take the tranny maintenance schedule with a pinch of salt. All transmissions are mostly aluminum, built to tight tolerances. Magnet catches steel but aluminum crud falls to bottom of pan and will circulate with even the minutest turbulence in the pan.

    I purchased a new ’06, highly electronisized Mercedes with lifetime ATF and Coolant. I serviced the transmission myself at 30kmi. Bottom of pan contained silvery silt thick as a river-bed. Problem is exacerbated when German vehicles no longer provide a means of draining the torque converter as in prior years. This opinion is not just personal but also based on consensus of a related, global blog.

    If you bought the vehicle used, be assured it was sold just when it needed other scheduled maintenance. Take it from there. Oh, and I would not skimp on installing new drain-plug washer – they seal when crushed; are consumables.

      Basil: Good point on the use of aluminum. It’s definitely more difficult to capture, and could be the reason Audi has such a frequent filter replacement.

      The Audi S-tronic transmission doesn’t have a torque converter; it has a clutch design similar to a manual transmission. Actually, 2 of them. But unfortunately that doesn’t reduce the maintenance frequency.

      And you are correct, I bought the car just when the maintenance was due. I had planned to do the transmission service myself, but the spark plugs also need to be changed at the same time, and that involves some substantial engine access labor. The Audi dealer service department gave me a very good quote on the work, which was fairly close to my parts cost. They actually tried to charge me more than the quote when I picked it up, but adjusted back to the quoted amount when I mentioned the original amount.

  2. I am about to knock out this service myself. THanks for the break down and link to the manual- I wish I would have found this before paying for the Factory Manual myself. There is just one question since I noticed a minor difference in your write-up vs the manual I purchased. It is recommended to replace/retrofit a new external filter cap as well(part 18 on the workshop diagram you provided); did you find that necessary or was reusing the original easy?

      I think the filter cap is supposed to be replaced. I didn’t have a clear description of the part or the part number, so I wasn’t sure at the time. Do you have the part number details?

      1. Yes it is part # 0B5325240B(fitted at factory) 0B5.325.240.C(retrofitted)

          Thanks. I updated the post. Please let me know if you find anything else that’s missing.

          1. I just wanted to add an important note from the workshop manual: make sure to verify the appropriate ATF filter cap needed the B version or C version are based on corresponding ATF filter housing version. To ensure the right fit and prevent leaks I wilI talk to my dealer for parts(they can verify based on VIN ) and after I knock out this service myself I will have more insight.

  3. Thanks for your manual. Do you still remember the size of the tools you used for the drain plug and for the external filter housing? I want to make sure I got them before I go to the workshop.

  4. thanks for the write up , however not clear..do you need to leave the engine running when doing the final fluid check, at 38c or do you just need to get the transmission to 38c then shut off engine and then check fluid, …as not sure if the transmission may take up an additional amount of fluid when running therefore changing the level

      Andrew, after warming up the transmission fluid, turn it off to check the fluid level.

  5. Interesting that this DSG uses a filter and pan, with side fill port.
    The DSG that I’ve encountered on TDIs (my friend’s 2006, parents’ 2009, and now my 2015) all have a filter not too dissimilar from standard oil filter (cylindrical). That’s on top of the transmission (have to remove the airbox and some other stuff to get at it); then you fill through the drain port at the bottom.

  6. Hi Carlton,

    Great stuff available. You dont have to change the MTF – the oil for the manual gearbox then (see right corner of your pic of the s tronic above). I have to on mine, another 5 liters almost of a different oil. Not sure I have the DL501 but I know it’s the OB5.
