Passat B8 ambient temperature sensor

[Mittens247]

Hi Stewie, did you manage to change yours? If so how did you access it?

If you have small hands and wrists you can actually reach through the grill and unplug the old one and refit the new one. If you have hands like shovels, you will need to remove the undertry at the front of the car. If you can get the front up on ramps or a few planks this will make access easier.

Hi All,

....rekindling this thread...as this fault has now occurred to our B8...

I've see a few YouTube videos on changing the ambient temp. sensor, but the comments are peppered with people complaining that their park assist no longer works and other assorted warnings/messages - after changing it. The videos show a pretty straightforward plug/socket type connector. I think my question is, what may have these folks done to cause that, and what should I do to avoid it?

A related question is that the online parts websites seem to have different parts depending on the car's engine, which seems odd to my mind - but I'm happy to be educated!..

As an aside, I noticed this morning the car would only send heat to the cabin if the climate control was set to 'HI' (the ambient temperature was showing 60C). I'm assuming there is some logic in the climate system to drive that behaviour?

Many thanks for any pointers.
