Third DSG change on the Sportwagen. Shorter change interval this time with increasing track usage; Liquimoly DSG fluid out/in w/OE-equivalent filter. I get my kits from FCP so this is my second one so free using Lifetime Replacement Guarantee. Seeing the impacts of track use with the up-tick in aluminum and iron (per 1K miles) and drop in viscosity but did see lower TAN this go around. Transmission shifts perfectly. I always do a full battery of the basic settings/resets when I do the service. I use the factory bottom-fil method. I’ll likely just start doing this once/year it’s easy enough to do and free.
