What would cause the rad fan to run from start up to switch off?

[toofunkyhouse]

My superb quality German engineered Car.... cough cough. Has another little electric fault (I keep expecting the Audi body kit to fall off to reveal a Renault Meganne estate I used to own) Sorry I digress. The cars fan kicks in after start up and only stops about ten seconds after switch off! Only fault I can find is something to do with the AC pressure sensor... Any ideas what I need to do? Rob

Any faults?

[toofunkyhouse]

only fault is something to do with the A/C pressure sensor

Rad fan on the right as you sit behind the wheel, aux fan on left, if you had a a/c pressure sensor issue it should be your aux fan that's staying on?

Could just be a loose connection to the control unit?

What was the fault code on VCDS?

It's the lest one. Will check the code tomorrow and post it. Thanks

well had a quick look, think I will just take it into Midland VW. At least I know its either the sensor or the wiring I guess.

Like Audi won't they want to charge you for diagnostics or are you just going to tell them to change the sensor?
