rmn 0 Posted November 15, 2005 Right, my fan on my 2L 16v keeps running, it drained the batt on me the night before last and now i have to unplug it to switch it off. Now i have not checked relay's etc because its dark, but is there a control unit for these on a 16v i know there is one on a VR, but not sure wheather its the thermostat or a control box that does the switching. Thanks Quote Share this post Link to post Share on other sites
Supercharged 2 Posted November 16, 2005 If you have ABS then the contol unit is in the engine bay near the washer botle, if not then it's where the ABS relays would be - ie up behind the passenger side of the dash... Quote Share this post Link to post Share on other sites
RW1 0 Posted November 16, 2005 Try check for a loose brown/white wire over by the metering head. It should be connected to the forward corner driver's side of the rocker cover. Connects to a sensor there. If the wire touches earth, the fan will run-on as though the engine is hot. http://the-corrado.net/.archive/forum/viewtopic. ... highlight= .

corradophil 3 Posted November 16, 2005 Sounds like the fan switch to me. I had the same on my Golf a few years ago. It screws into the N/S of the radiator, unplug the electrical connection to it (either 2 or 3 pin) and see of the fan stops, if it does thats your problem.

rmn 0 Posted November 16, 2005 Thanks Lad, i think its the fan switch, there is no run on switch on my engine, but when i went down at lunch to have a look at it, i tried it and the fan didnt come on, it seems to have fixed itself, i think that means it time for a new thermo switch. Wierd prob Thanks Again Quote Share this post Link to post Share on other sites
corradophil 3 Posted November 16, 2005 Just remember if you leave it un plugged your fan will not work. Quote Share this post Link to post Share on other sites
vw rule 19 Posted April 19, 2014 Had this on my Corrado 2.0 16v today the dam radiator fan wouldn't turn off, traced it to a warn out fan over run sensor, this sensor is screwed into a bracket which bolts to the front left of the valve cover, plus it's yellow in colour and has just the one spade connector on it. Original OEM part number I think is / was 191-919-521D Managed to find a seller on Ebay that has them in stock, so have ordered one. Ebay item number 400360578030 Ebay item Link below: http://www.ebay.co.uk/itm/400360578030?ru=http%3A%2F%2Fwww.ebay.co.uk%2Fsch%2Fi.html%3F_sacat%3D0%26_from%3DR40%26_nkw%3D400360578030%26_rdc%3D1 Hope this helps anyone with the same fault.
