Selecting Reverse And The Heater Fan Changed Speed

[Dannyb6467]

Morning all.
Noticed a while ago that when I select reverse (DSG) the heating fan speed seems to increase and change from where the flow is directed??
Anyone else noticed this??

When you select reverse the heater automatically sets to 'recirc' to avoid any smelly exhaust fumes entering the cab..... i think anyway ....This makes the fan noise increase slightly.

That would make sense.

Yep that and the stereo going quieter which annoys me as I'm usually listening to radio 4 and I miss something

Yes, noticed the same and assumed it was as Danny explained.

Cheers folks. Nothing to worry about then.
Cheers as always.

And the rear wiper if it’s raining.

And the front fogs light up as mentioned in another post.

The other points make sense but why do the front fogs light up ????

I've not noticed that, I'm going to have a look next time. Seems odd, I can't think of the logic in that

It's to show where you've been.

The man that can understand the logic in VW's programming engineers is a better man than any of us, but no doubt there is a reason.

For some reason the van goes backwards when I select reverse.

I'm guessing most reversing manoeuvres are slow and often involve steering lock. I can picture myself reversing in tight areas and looking at what the front is doing as much as the back. Therefore the more low down light shone on 'hidden' rocks, kerbs, posts etc, the better.

Try that sitting in the driver's seat with the steering wheel behind you. Is it the same?

Yes, but does it get getter MPG in reverse?

Or if you have eyes in the back of your head.....like my dad!!

24, you're so sensible.....

I'm not quite sure the guy in the BMW M4 would agree as he witnessed my lift-off oversteer.
