This is a great test. I’m repairing one of these right now. Getting the 7 speed DSG out is very difficult. I hope I can get it back in without removing the subframe.

Thanks for showing this.

So the engine is sucking the brake cleaner through the rear main seal and recirculating it into the intake?

Exactly! My seal completely separated from the metal housing.
