Cooling and airco fan keeps going on till battery is dead

[Jeuxnathan]

Hello,


I have a problem with my Rocco.

Last week my battery was dead but hence the cold weather I thought it 'could' be normal.

But now it seems that my cooling fan and airco fan keeps going on and off even when the engine is off and cold.


when I pull the key out of the ignition, it takes about 2-5 minutes and then both the cooling fans go on at full speed for about 2 minutes.
Stay off for like 30 seconds and on again for 2 minutes. Continuing till my battery is empty.


Does anybody have an idea what this could be? Some sensors or some electronic faults?

Warranty ?, take it to the dealers ?

If you have got VCDS or access to it, check for a fault, DTC 00819. It most likely that your AirCon G65 High Pressure sensor is out of tolerance. Could also be a broken wire at the connector.

Replace the sensor, part number 1k0 959 126D. About €35 - €45. Warrenty claim is possible, known problem. Not an easy place to get too either. Discharge/Recharge Aircon + Bumper off?

Okay thank you!

At the moment he is with a friend who has a Vagcom system so we'll check it out first.

I recently had a small accident so I replaced the front of my Rocco. Had the airco refilled and it occured after that.
Could it have to do something with a bad filling?

Yes. May have cracked the pipework at the front allowing gas to escape.
