Hi there - i checked through all the pages related to A5 but didn't see anything on this topic on issues with the one-touch open/close function.

I have an Audi A5 Cab B9/F5 40 TFSI S line (pre-facelift) and on the cabriolets, you have 4 switches, one for each window, plus a 5th master which does all the windows at the same time. Each switch has the one-touch operation. The rear window switches and the 5th master switch work up/down with one touch no problems.

Problem I have: The front window switches, driver and passenger, are not working as expected. Both have the same problem with the one-touch function when you want to open the windows. I have to manually hold the switch until they are fully open. It seems to only be opening them where the issue is as they both close fine using one-touch. NOTE: they also open fine on one-touch from the master switch.

Possible solutions I have tried:

I have tried the re-programming approach to lower and hold for 10-15 seconds and then raise and hold for 10-15 seconds. But not sure if I am doing it right or if there is an authoritative source on the exact process? Maybe I need the ignition on? Maybe I need to lower first then raise, or raise first then lower?

Possible solutions I am aware of:

Would disconnecting and reconnecting the battery force a reset? Could I impact other items by doing this though, will this lose any other settings or config I should check first?

Replacing the switches might fix it but whether or not the behaviour above points to this or is it more a re-programming issue than a hardware?

Cleaning the switches might also be something to try? Removing the switches from the arm rest, giving them a magic blow/spray with electrical contact cleaner.

Help I need:

• does anyone know the specific re-programming process I need to follow? Not sure if it's documented anywhere?

• if I disconnect and reconnect the battery, is there any risk to any of the other systems? Not bothered about losing radio stations, MMI settings, NAV favourites as I use Apple CarPlay. Trying to think of any other settings I might worry about if they were reset...

• any other options before I go down the cleaning or replacement of the switches

Thank you in advance!!

That is the right technique, but the ignition needs to be on.
