I had an oil change and then days later the battery was totally dead, i have changed the battery and as soon as its connected there is a fa noise coming from the passengers side wheel arch, this doesnt go of and again drains the battery, does anyone have any idea what it could be before i put it into a garage
Are the radiator or A/C fans still running after turning the ignition off?
Testimonial: "i think it's the A/C fan, the noise is coming from the passenger side at the top of the engine not the radiator Fan"
VW has a common problem with the fan control module (FCM) relay sticking on, some are built in to the main fan unit and some are a separate unit.
Thanks very much for the information, I will try and have a look online to see how if i can change this and if not get it booked into a garage
Just did a bit of searching and found a post that indicated fans could also stay on due to a faulty coolant sensor, if not then look at the FCM and it is built in to the larger of the 2 fan units on the Touareg.

Sounds like a relay is stuck on pull the relay and use a volt meter and check continuity on pinouts, if you have a resistance reading on 2 pins of 0.0 that means the relay is stuck on. Replace the relay.
