I changed out most of the sensors before doing some major work on the AC system. The pressure switch on that ended up being the thing that solved my high speed fan issue.

I had the same thing after the front came off my car for piston work. Car sounds like it's about to take off into space. There's a switch or thermostat that's adjustable in there somewhere. It's only supposed to go nuts like that when you turn the car off and it's seriously hot. Shouldn't be a big deal to find and fix it.Originally Posted by The_Hawk

Can anyone point me in the right direction where the pressure switch is?

Drivers side near/under the head light, next to the receiver drier.
Has an electric connector on it should twist off a schrader valve.

Can anyone tell me where are all the temp. sensors located in the TFSI engine/ Audis3 8p /Golf mkV1.

OK......the problem with the fans was because of the thermostat. Took it to Prestige and Performance after changing the main fan and coolant to the engine block myself with no luck. They thought it was unusual showing no code errors and after a bit of investigating they said the thermostat needed replacing. Funny because that was the next thing i was going to change, but too much of a hassle.
