    New owner- maintenance and warranty questions

    Guest-only advertisement. Register or Log In now!
    Purchasing a relatively high mile (~44k) 21 Premium plus with s sport this week. One owner dealer maintained.

    Car looks well cared for but this is my first German automobile and I understand maintenance is important and want to get it dialed in prior to tuning and modifying.

    At 44k would the trans/ diff fluids need changed? Anything else I should do around this mileage?

    Also curious about extended warranty. I’ve searched the forum and it seems the consensus is the Audi platinum plan is probably worth it for the right price? Does this sound right?

    I have the Audi Pure extended warranty. Just used it for water pump replacement. Had coolant migration from WP to vac lines. My 2020 PP S4 has 69k when the water pump failed. Seems to be a common issue.

    My independent shop recommended trans fluid drain and fill around 50k miles I believe. Audi states the trans fluid is lifetime but ZF who builds the trans has a fluid change interval posted. I think at 80 or 100k you should also change the trans filter.

    Unsure about the diff fluid change but it cannot hurt to drain and fill.

    How much are you paying for the car? I'm possibly selling mine, but it's on the higher side of the scale due to it being an Audi Exclusive color. It does have 50k miles. But, mostly dealer maintained and just had the water pump and related parts replaced, new key, and new brakes up front.

    To get the owner's manual (which will have the maintenance schedule), enter your VIN here: https://ownersmanual.audi.com/home/.

    I also have a MY2021. Maintenance is quite low TBH - nothing special/tricky/sensitive to keep 'er on the road - 10k mile oil change intervals, 20k mile cabin filter interval, 40k mile spark plug interval, 60k mile engine air filter interval, 2 year brake fluid swap interval.

    Tranny/t-case/diff are lifetime fill - such service only mentioned for the RS cars and the likes of the DCT cars and SQ7/SQ8 are referenced for such service. Radiator is never mentioned for any MY2021 Audi.
    2021 Audi SQ5 Prestige SSP w/Sport Exhaust and APR Stage 3 (91 octane) - 0-60 in 3.5 s and 1/4 mile in 11.6 s @ 117 mph
