I've read somewhere that putting on a turbo timer is a waste of money because S4 has the after-run - Page 2

you have the infrastructure built-in...pump/thermoswitch/extra fan/fan control module. might as well use it.

would i rely on it? no...id do the same cool down you are recommending on top of a thermo switch mod. imho.

I don't even know where to look for one, but I think it's a great idea.

keeping in mind i'm an EE, not a ME

exactly WHAT does the thermoswitch do at what temp, current rating, voltages, etc.

QCRAZY · 04-20-2004, 11:22 AM

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.
