2 questions; Key fob battery and steamy windows

[Wrex22]

Does anyone happen to know what battery is required for the 2015 gti key fob - keyless entry but with the flip key if that makes any difference , getting a message telling me to replace it, thought it would last longer than 12 months tbh.

Also, when I leave my car when I come back the windows are steamed up, there are no damp coats etc left in the vehicle, I have even felt the footwells incase they were damp but they seem dry ( unless of course it's wet deep in the sound deadening)

1).Sorry don't know.Maybe in the handbook?.Should last longer than a year.I would just start using the spare.

2) Make sure your climate control is set to Auto.I think the recirculate air button is manual so it won't be that.

Prerry sure it takes a CR2025 battery.  The average battery life for keyless is 1 year.  Just had mine changed at 1 year after low battery warning and I know others with keyless had the same. I got the dealer to change mine at first service and they picked up the tab.

Always a quite divisive subject steaming up of windows and everyone has their own thoughts. My personal experience is that running climate control/aircon is the answer to misting up.  Not had a single misting issue on my R and run aircon all year round.  Some people put silica gel pack in their door pockets to absorb excess moisture in the car or some use Pingi dehumidifier bag.

I've read Keyless is always communicating with the car so its battery is being used regularly hence why it drains quicker than a car without.
Its a CR2025 according to this "How to change the battery" https://www.youtube.com/watch?v=cE4fx5pLNXo


As for the windows steamed. Do you use the AC?
My windows were always steamed up when I came back to the car if I had used AC. Stopped using it years ago and never get steamy windows.

I always remember my old Dad telling me after he bought his wee Honda Jazz how the windows kept steaming up.He asked his neighbour about it who promptly informed him he had his A/C button set to 'recirculate'.Switched off-end of problem.After that,he started reading his handbook!.
Like yourself,i run my all the time,all year round.I paid for it so i'll use it.Never have a problem with 'steamy windows'.I feel a song coming on!.

Battery is CR 2025. Costs about 3 quid in your nearest supermarket/chemist and takes about 30 seconds to change it. It's really not that big a deal...

I've had 2 MK7's with keyless and got the low battery warning in both around the 1 year mark.

I'll be looking out for it now then.1 year and 2 months in.

I've just passed the three year mark and changed the batteries for a second time a short while ago.
