Great, I've ordered a genuine one from the link @Keyo provided. I've found that non-genuine ones are a bit hit or miss from previous experience. Hopefully that does the job and makes them work during normal operation. I've since asked the PO about the operation of the fans and apparently, the single running was how he deliberately set them up. I think in the future, I'll look into rewiring and getting both working.. makes more sense in my mind.

Thanks all! It'll be sweet as once I've sorted all these little bits. Went out this morning to test the radiator switch and got the following results: In both test cases, the override switch switches the drivers side fan on, I suspect it may be wired to stage 1? Igntion off Bridge rad switch top left and bottom pin - one fan, drivers side (Stage 1) Ignition on Bridge rad switch top left and bottom - one fan, drivers side Bridge rad switch top two pins - one fan, passenger side (Stage 2?) I need to test the black sensor for stage 3, maybe that'll trigger both fans.. Either way, it looks like the rad switch could be knackered. What do we think? Will chuck some pics up of fan wiring when they've uploaded to imgur.

Thanks mate, I'm happy with it overall. I think it was a good price. I completely missed that guide, I'll run through some tests tomorrow when it's light again. I'm hoping it's something simple like a dodgy rad switch!

Long time lurker of this forum, I've finally decided to jump on the bandwagon. In the wait for my mk2 golf to be 3.2 swapped, I decided I'd fulfil a want of mine to own a Corrado! Enter this Corrado VR6, finished in Aqua Blue Pearl... The previous owner has spent a lot of time on this one it's had a full engine rebuild, respray, chassis/subframe refurb, uprated brakes, Jetex system & 6 branch and loads more. It did however come with a few faults: Failed to start/turnover - I've replaced the ignition switch and this had fixed the problem. ABS light is on - Need to scan with VAGCOM. Radiator fans don't appear to work correctly. Speedometer + spoiler don't work intermittently - I've ordered a speed sensor for gearbox as this seems the likely culprit. Now, hopefully you can help with the fan issue, as that's most pressing at the moment. It has an uprated, slimline set-up fitted on an alloy radiator. The car does get rather hot in traffic and as far as I can tell, the fans aren't kicking on as they should.. The only time I get a fan on, is when I switch the car off.. and only one of the two fans spin. Is this correct for over-run to only run one fan? Now, what should I be checking? I've had a look through various forums and my issue seems slightly unique. I'm guessing I should first check the radiator switch on the bottom of rad on passenger side first? It's also worth noting, the previous owner fitted a manual over-ride switch to turn these fans on, which I suppose I should have been more cautious about. Appreciate any support or links you might have, I'll post up a full thread soon as I've done a fair few bits already. TIA.
