Hello,

I have a 2016 a3 2.0T AWD and my DSG has become very clunky. At low speeds or high speeds, up shifts and down shifts, almost through every gear it bangs gears. You can really feel it like shifting poorly on a manual trans. It can be felt and heard as well with loud clunks/bangs. The transmission hangs a lot between down shifts as well. Some times going from 3rd to 2nd it takes like 2 or 3 seconds to engage. Its been doing this for about a year and a half now. I had the fluid and filter changed about 20k km ago using Liqui moly, including front/rear diff and Haldex. Along with basic setting and adaptation, it made no difference. Recently now at idle at a light with my foot on the brake, I can feel the whole car shaking sometimes. Which stops when I put it in neutral.

Has anyone experienced this? Could it be worn clutches, Mechatronics, or maybe the Mechatronics connector has corrosion or bad ground?
Is there any data logging I can do to rule out one or the other?

I do get faults, but they only come up after the car is driven. If I start the car and scan it will be clear. Once I turn the car off they clear again until the next drive. So far after a year and a half I never lost a gear or went into limp mode. Nothing has ever come up on dash.
I will post them below.

Thank you

Is the gearbox oil and filter changed?

Arthur555

Yes, I did a early change at 130,000km (dsg oil and filter using liquimoly dual clutch gear oil 8100 + basic setting and adaptations) as I was feeling symptoms then already. It made no difference, also did the front and rear diff fluids and Haldex service. Car has 148,000km now.
