Radiator Fan

[rudyno9]

I understand with the A4 that the raditor fan can sometimes come on automatically when the ignition is switched off to cool the engine down.

Just the other day, mine as started coming on and not going off, so was blowing away all day.... when I turn the ignition it goes off. Came home last night after work and the same problem, eventually flattened the battery

So just now I have pulled the fuse out for this whilst the car is parked and put it back in when am driving.

Anyone any ideas, need to take this to the dealer to get looked at?

Thermostat??? Coolant Temp. Sensor???

The temperature gauge displays fine.... no problem at all.

Should it be a big job to fix ?

internal fault with fans

fault find ... pull the fuse to the aircon (fuse box under panel on end of drivers side dash) when it is doing what you say it is doing, then u know if it is that or something else.
from memory there are 2 fans, one which is belt driven from the engine and another electrical one which is for cooling the aircon radiator when stationary, so maybe that is your problem?

Thanks...

will need to see what Audi say... does it have to be fixed by Audi or would I be better off taking it to my local garage etc ?

local audi specialist as well cheaper!!!
audi will charge to diagnose the fault (basically checking the computer for the error)
