I believe that only early VRs have a 2-stage fan setup. Possibly all and certainly all late VRs have a 3-stage fan setup. Essentially, if you've got 3 temp senders in your thermostat housing, you have 3-stages. If you have AC or an auto, you'll always have a 3-stage fan setup regardless of age. Fan switching temperatures while the engine is running These are approximate as it depends on the age of the senders and how crusty they are. VAG-specified values and part numbers are listed further down. Stage 1 Controlled by the temp sender in the rad, directly to the fans Switch On: 92-97 C (198-207
