Audi 8

[wildgu6]

Hey guys, can anyone shed some light on my little prob.
Miss's got an Audi 8, V6, when she turns the ignition off the cooling fans keep running. Only way to stop them is to disconnect the batt.
Took to auto elec and had him stumped.
Any ideas for an electrical dumb &?$$

Guessing the auto leccy would have checked the fan realy ?

Did he put a scanner on the car , to see what reading the temp sender is sending ?




Mmm audi, good luck with that, if your not sure, the manufacturer even puts the resale value is on the grille for you (lol)

Also check the wiring loom for rodent damage. We had rats chew some wires together which caused weird stuff like the aircon coming on and the engine starting with the key in the 'acc' position.

i think all the fans run until the temp drops?? or am i wrong.

Yer Stropp that's how they work but these stay on all day if not disconnected.

Yer Steve, checked the relay, didn't see a puter in his shop, just your basic leccy, so don't think he scanned jack.
Might dismantle for parts and get a new Trol lol

Id get someone with a scanner to see what the car has to say first, really not the sort of car id want to be poking around just guessing with.

Definitely get it scanned first, euro cars are smart, too smart actually coz they even log a fault code when you change a light globe. I had a quick read of that link and the fault of that car was that the fan was working flat out while the car was working. But like they said you could have a fan computer fault or if the audi's are like the bmw's and have an electric waterpump for the heater that can cause all sorts of dramas. It'll be VERY VERY expensive to guess and replace parts so go get it scanned, even if you go to the dealer and pay for an electronic diagnostic report which may cost 100+$ to be certain.

And from memory they do have a function that the fan stays on after the ignition gets turned off to cool the motor down but it shouldn't stay on longer than a min or 2

Yeh, for sure it will be a variable speed computer controlled fan too, just to pee you off (lol)

G`day Pete
Wish you had posted yesterday as I had a meeting with a couple of guys today who may know a Audi mechanic.
Will try and contact them tomorrow and see if I can get you some help.

Starting to think George hit the nail on the head. Been to auto leccy, no idea, got it scanned today at cartoys, no idea. Spoke to several Audi repairers and tried there suggestions, no luck. Even runs with no relays in.
Only fella that sounded promising is booked solid for the next month.
3rd time lucky. Got it booked in tomorrow at another leccy recommended by the above. Specialises in euro makes. Fingers crossed as the miss's is gettin gnarly.

Can you actually see the cooling fan running?

The only reason I ask is my old neighbour had one and he had a similar problem with his but it wasn't the radiator fan that was staying on it was some sort of pump motor that was staying on instead.

In his cause it was a faulty relay.
