I may be preaching to the converted here but I reccommend that particularly any Bora V5 or V6 owners check that the cooling fans are working.
There are a gazillion posts on VW Vortex about it but I haven't seen any mention of it here. Apparently it is a very common problem.
You need to check that both fans on the radiator are running whenever the air conditioning is on. Doesn't matter if the engine is hot or cold. If the air is on and the motor is running then both fans should be running on the low speed. (They are 2 speed fans)
Recently some other VWWatercooled friends and I took a relaxing Sunday drive from Samford up to Mt Glorious. Those of you in Brisbane that know the road will understand what I mean. Anyway I was forced to suspend play about halfway up because the temperature gauge was entering the danger zone and the ECU was flashing all sorts of messages like 'STOP', 'Check coolant level' 'refer service manual' etc.
Well I had the fans ripped out on Monday. One wasn't working at all and the other was only working on high speed. In normal driving including stop start situations I had no indication of any problem.
The Vortex site suggests that the problem is with the internal resistors in the fans. Snap! The resistors in both fans were stuffed, plus the brushes were worn out on one fan. The local Dub dealer quoted me roughly $335.00 for one and $375.00 for the other fan and thats trade.
There is a fix on the Vortex site that involves fitting external resistors and I am going to try that. I managed to track down some new brushes for the non working fan and it is now working again on the fast speed. So by tomorrow (hopefully) I will know how much I have saved by fixing the fans instead of coughing up for new fans which I am sure is what would have happened if I had taken it to the dealer.
I will keep you informed if anyone is interested.
