Anyone able to post the Adaptation map of Module 5F of any B9 car that came with massage seats from the factory. I've got everything working but can't seem to get the MMI menu to pop up that changes the various massage functions.

These are already turned on, but still no MMI menu is visible


Code:

Are you sure massage seats = pneumatic seats?

Sorry Massage and Pneumatic functions are not the same. But the side bolsters are filling and deflating as needed. I'm just trying to get the menu on the MMI that needs to pop up to adjust the seat settings like the Massage function.

I'm surprised you don't have any Component Protection errors - or do you?

Then revert those channels back to stock, and have a look in the coding/adaptations of the seat modules and central convenience/electrics. I have no in-depth knowledge about this car and no auto-scan, but normally seat functions like that pop up in the seat menu which you probably already have if you had electric seats. Enabling a menu is usually done in 5F, how many menu items there are is usually decided by 5F based on what the respective control modules report to it at reboot. So if you have added a massage function, my best guess would be to tell the seat controller you have done that (which you probably already did), enable the bit and/or adaptation channel in the seat module and/or central electrics/convenience that it needs to present menu/personalization options, and then reboot 5F. Experimental coding could help you if normal coding doesnt show any relevant bits. Using keywords like ‘menu’, ‘sichtbar’, ‘HMI’ and ‘verbau’ should show you any channels remotely relevant to what youre trying to achieve. Make admaps before you change stuff and if youre not sure; do yourself and us a favor and lead with stuff like an auto-scan and admaps of any relevant modules next time.

Typed on phone so please excuse me for any typos.

Hi, o33err did you ever get the massage function fixed on this I have a very similar issue after retrofitting massage seats I can not get the MMI to display the massage / lumbar functions when the button on the seat is used. If you have fixed it what did you do?

I get the following fault code on my 5F

1 Fault Found:
