Switch has a 20mm housing, connects to a 2-pin plug. At 112C the switch closes and completes a circuit to the ECU. The switch sees +12v and very little current (not sure on amount).

The easy part is finding another thermoswitch, the hard part is finding one that fits a 20mm opening since most of those use a 3 to 4 pin sensor. Also, most thermoswitches are M10's no 20mm. The one to replace the current model would best come on around 100 to 105C. Most Audi TS's are set at 110C, some at 118C.

It's one thing to "say" it's easy; it's a whole other ballgame actually doing it.

Current Audi Count ---> 5


Previous Audi Count ---> 7

In spite of dealers; I still love Audi :-)
