Hi guys

I have a 2007 Audi Q7 3.0 TDI and the tempurature reading is not correct for the external tempurature.

For example, it usually says somewhere between -5 and -3 degree's even though it will be (example) 15 degree's C in reality.

I've bought a new ambient temp sensor as they are only £7-8, and had a look as best I could around the front area of the car (bumper on of course) but could not see where it goes?

I assumed it would be mounted at the very front of the main radiator or something????

Can it be easily accessed? Surely not a bumper off job???

Any help much appreciated!
