Stumbled across the rain closing mod on
www.golfmkv.comBasically it shuts your windows if you leave them open and it rains. You get a new addition to the menu in the FIS too allowing you to turn this on and off.


The procedure involves going into menu 46 Comfort System Controller, set Byte 09 from HEX 04 to HEX 02 (you can also use the tick boxes in the long coding helper)
I did this and everything worked as planned. I poured a glass of water over the sensor and the windows rolled up. There are a few conditions. The car has to be locked, it does not kick in straight away (usually after 2 mins) and it disables itself after 24hrs (presumably to save the battery as the sensor will be on)
The only confusing bit is there is another change to make in VAG COM, you have to go into the central electrics (09) and change a few things there. It wasn't explained why you had to change them.
EDIT: See post further down for variation on the following procedure.
Part No: 1K0 955 559 AF
Component: RLS 260607 046 0204
Coding: 00207646
Shop #: WSC 05055
Change 00207646 to 00469790
The first number on mine was 00208933, I changed it to 00469790 anyway and there doesn't seem to be any adverse effects. Does anyone know what this bit means?
Oh, and if anyone wants to know the pics above were from the American spec car in the thread and "ATA Confirm" on the menu is to do with the Anti Theft Alarm, apparently you can turn the beeps on or off when you lock the car, rather than using VAG COM
