I experimented with different fixes before trying this one and others worked but were not as good as this product.

Since he seals are all the same on BMW v8s I'd suspect it will work fine on the s63. Which i may be finding out. As I just dropped mine off at the dealer for smoking....... but this one is not showing any of the symptoms my n62 had. The m smoked after a full throttle pull and you let off the gas to idle. Hoping it's a bad pcv or turbo seal.

sounds like a turbo seal

I ordered some yesterday, I just wish I could have used it during my road trip from Hollywood to Seattle to really let it soak in vs my 30 min daily commute.

Old thread but new member looking for answers and ending up with even more questions to ask!

Had anybody else used a seal reviver like AT-205 on an S63 with success (or failure)? Mine smokes a bit and I'm considering doing this. Looking to learn from others' experiences, good or bad.

I have used AT205 on a S63 and blue smoke after long idle disappeared. If you're having a similar issue I'd suggest to use it and it should take about 5 hours of driving for it to work. I used the whole bottle.

Thanks

Do you just add the ATF-205 to where you add the oil?

It could work for a while. Nice I you wanna sell a non smoking car, but keeping the car with no smoke will result in solving the problem in time.
