Hi all!

Curious if anyone has had a similar experience -- have a 2017 A4 with ~70k miles. It was working perfectly well, and I took it to a local place near my house for an oil change. (BIG MISTAKE) Long story short, despite assuring me they work on audis all the time, they later called me telling me the car no longer drives and is billowing copious white smoke. After a tow trip to the dealer, turns out they drained the transmission fluid and double filled the oil (11 qt). Dealer was able to drain the oil and refill the transmission fluid and the car runs smoothly again even after testing it on the interstate for an hour or so. Their inspection didn't find any other issues other than the oil place induced ones

However, now I am dealing with a significant amount of white smoke from the exhaust when I drive, especially at higher speeds. I've been told this should resolve in a few hundred miles, but wondering if there would be any way to speed this up. One thought I had was trying some seafoam in the gas tank, but I am concerned it wouldn't help or make things worse

Appreciate any advice or help!

Who's paying the bill for dealer work and tow?

Certainly the oil change place would be responsible. I’d be a little concerned about seals, the catalytic converter, the spark plugs, and valves being carboned up with all that excess oil. Maybe ask the dealer to check/verify after you’ve driven it a few hundred miles? The lube shop should be billed for any related parts/labor if needed.

I certainly wouldn't go adding a random foreign object to the mix like seafoam. If you have it on paper that the smoke condition is acknowledged and the directive is to let it go as is and should correct in a few hundred, then that's exactly what you do. If it does not correct as directed by the dealership, then you tell them to finish addressing the issue, billing the oil shop whatever it takes. The second you throw seafoam in there, you're on your own.

Seafoam is petroleum based, that would be the last thing I would introduce into this equation. I wonder if you have oil residue all in the turbo, the pcv, and the charge pipes. Stands to reason that fresh oil would likely have made it that far up the crankcase vent system.
