Was booked in today for a Haldex Oil & Filter change on my '58 S3 (Facelift Sportback). Apparently my car has the Gen 3 Haldex system, which is sealed for life and so there are no parts listed for Oil or Filter based on my VIN number. According to my service book, an Audi dealer did an oil change about 30k miles ago...god knows what they put in if they did! Has anyone else encountered this with a similar age A3, did you manage to get the oil & filter changed?? Any part numbers?
