Fan issue with my PD 130!

[CHR15B]

Hi folks,

Don't think I've ever had anything go wrong with either of my TDI's but it looks like I have a bit of an issue now.

My car has Climate Control and thats on all the time, I don't use it on ECON so the air conditioning I guess is running all the time.

What my problem is, is... the two radiator fans do not spin at a slow speed - they do absolutely nothing then at random (I guess its pressure related, as this happens when the car is cold) both the fans kick in at a high speed (Can see the volt meter jerk a little).

Any ideas what this could be? A sensor? A fuse? I'm pretty clueless, any help appreciated.

Had a new radiator fitted recently and it's still the same.

Thanks, Chris.

This is normal they kick in about every 40 seconds and stay on for 4 seconds, mine does this as yours is doing so dont worry this function is air con related you will see it stops if you turn the air con off

Not too sure but I thought that with aircon on the drivers side fan stays on all the time and fans that are spining at high speed intermittently was a sign that the fan controller was bust.

May be wrong but that was my understanding.

the second post in this thread http://www.seatcupra.net/forums/showthread.php?t=77321&highlight=fan+controller also mentions this problem

Well guys - found out the answer.

If your air con is on, and the radiator fans are not spinning at a slow pace then basically you need a new fan assembly. If they kick in at high speed only for about 5 - 10 seconds is a good sign of this.

The replacement assembly is £200+VAT ... plus a few hours fitting.

There are other methods and fixes around this though - have a look at the link below, turns out its a VAG thing .. not TDI.
