It was very bizarre. A simple reset would not turn the warning off. In the end, the only thing that would was for the ECU to relearn the sensor (or have it reassigned or what-ever you want to call it).

This was when I had allowed the battery to run low on voltage by running a tyre compressor off the cigarette lighter, without the engine running (the car started immediately afterwards and the light came on after a few miles of driving). The sensor was not disconnected at any time, but the ECU could not detect it was present until it was specifically told to "look" for it.

what are peoples opinions/thoughts about removing the viscous fan and replacing with a slim electric puller?

removing the AC isn't an option for me, as much as this offers a first pass of clean air into the radiator

BUT

way i see it is the viscous fan doesn't exactly offer a clean path for the air to exit once it has passed through the radiator


even my 21 year old Audi S2 runs an electric fan and can regulate temps ok


slim fan can be controlled by something like this

leaving the OEM aux fan there as a backup if the slim fan was to fail

I was lead to believe from the American forums that the OE ECU can control the SPAL fans - you just need to wire them up to the factory controller?

I was also thinking about the cooling issues on my car (or lack of them) and wondered if perhaps the Vorsteiner front spoiler helped direct some more air into the radiator mouth on the bumper, where the OE set up does not? Just a thought....

Mine never got too hot at the Ring. Only shorter tracks.

fuck me Mike, some big price to pay for having a better cooled car

cheers for the link - had a scan through

in that case, if you have the electric aux fan, is there any need to run the viscous?!

The US guys I have spoken to have deleted the two OeM fans (to get better flow trhough)and replaced by a high flow Spal. Cooling problems sorted on hot days on track but occassionally get overheating at slow/stationary speeds on hot days

hard to find the optimum compromise i guess

i think that all fans in place and a better radiator could do the trick - got some feedback from turner motorsport on the email and they have had great feedback from customers running the fluidyne radiator

HOWEVER

i did read a thread online about someone who upgraded the Auxiliary fan to a SPAL fan that had a higher CFM rating - ran that combined with no viscous fan and a motorsport thermostat. seemed to do the trick
