Retrofit touch column stalks from G11 7-series

Hi!

BMW has changed from touch column stalks that returns to the 0-position in use and with button for the rain sensor on the wiper stalk to mechanical versions. Has anyone retrofitted the G11 steering column with this handles?

I was trying to do this yesterday, and everything works perfect except of the turn signals (the 3-blinker works). The car just make 1 blink when you turn the turn signals on. If you hold the handle upwards, it blinks as many times you want, but it will cancel immediately when you release it.

As I have read, the the steering column communicate trough LIN-bus to BDC, so I can't really understand why the turn signals won't stay on.

I'm a little confused here. The G30 and G11 both have the exact same turn signals and wiper controls in the online part lists, and also in pictures comparing the two. What are you trying to swap between the two cars?

Thanks for input. Will try to check if its possible to change some values in BDC.

The SZL is no longer an control unit, so its not possible to code.

The first MY G11s had touch-handles like all other BMW models. After 03/2017 (or 07/2017), BMW changed to the G30 mechanical stalks.

Here are the touch column stalks: https://www.ebay.co.uk/itm/GENUINE-BMW-G11-G12-STEERING-COLUMN-SWITCH-SWITCHES-RING-9383676-6806353-/303228997913

Got it, I was unaware they had kept that variant on the early year G11's. I believe mrgicm is probably correct. You would need to make sure the BDC has the latest software, as there is coding related to the SZL variant in the BDC. If your I-Step level is older, it might not have the newer options in the coding.

Maybe its a stupid question, but I'll try anyway.

Do I just have to code the BDC and the car will recognize the SZL and how it works? Or do I have to do expert coding with changing different values etc.?

Hello, since my HBA Button doesnt work properly in my g30, i find this quite interesting. Have you figured the problem out? Is it plug&play? i have paddle shifters, vibration and driving assist, which stalk do i need from the g11? is it 6821582? what coding needs to be done exactly?

Did you ever get this feature working? Trying to solve this on my '18 540d (US) I've seen several videos of tis retrofit working correctly but can't find any details on the coding that fixed the single blink problem.

Yes I know it's an old post, that's why there's a search function, right? ;-)

Yes, i managed to get this fully working. IŽve done several retrofits for BMWs here in Norway - F20s, G20s, G30s, F90s and i4.





YouŽll code the BDC. I canŽt remember 100% what it says in the FS_tyo and WW_szl, but i can connect esys and check.

r=rastend

FS_TYP_SZL -> nicht_rastend
WW_SZL_TYPE nicht_rastend
LIN_VARIANTE_SZL -> to same as you have without _r_ in the name
LIN_VARIANTE_SPARE_SZL -> same as above
