[INFO] Coding Sunroof to auto-close when it rains
In light of the guy here who got his interior rained on because the sunroof was open, I decided to see if the auto close function can be coded on the G30. IT CAN!! Credits to this post over the G05 forum.
Tried and tested on G30 LCI. HEADUNIT (HU_MGU) • EXPERT MODE: 3000 HMI_SPEECH > REGEN_SCHLIESSEN = aktiv [Add sunroof close to iDrive menus] ROOF FUNCTION CENTER • EXPERT MODE: 3009 SHD > Regenaktiv = aktiv [Activate menu selection in iDrive] • EXPERT MODE: 3009 SHD > Regenaktiv_robust = aktiv [Sunroof close in rain] • EXPERT MODE: 3009 SHD > StatusRCTime = Defaultwert [Default time for closing] • EXPERT MODE: 3009 SHD > Regenposition = geschlossen [Roof fully close in rain (set to close to tilt mode otherwise)] It uses the same rain sensor your wipers use to detect rain. To test, open your sunroof, lock your car, then pour over the sensor that's in the middle of your windshield (below the KAFAS camera). The sunroof should automatically close. On iDrive, the option will be on: Car > Settings > Doors/Vehicles Access |

How long is it “active”? In terms of looking for rain? 1 hour? 8 hours? 1 day? Curious if there is a point where it goes into a deep sleep and you might still be at risk. Like being at the beach all day and the weather goes south after 5 hours of something.

Very cool and very useful. Have you come across whether this is do-able for pre-LCI?

The pre-LCI and LCI uses the same Roof Control Module (61315A7C489) so I don't see why it wouldn't. The only issue would be IDrive 6 having a different variable to show the checkbox on the infotainment. But it's worth checking for it because they sometimes don't change it. |

Pre-LCI here: I love it but the only problem I've had with it is that when you wash your car it panics and the mirrors fold and unfold constantly (and the sunroof shade also opens and closes) Even if you force the car to remain unlocked, the moment it detects water it goes into panic mode. |

Somewhere in the cobwebs of my mind...I thought I'd read that it will close the sunroof when rain is detected...and after 6 hours will close the sunroof regardless of rain or not. EDIT:...the answer was in the very 1st post found at the link that was given above that had the coding parameters: Quote:

For closing when it is raining Principle An open glass sunroof is automatically moved to the raised position when it starts to rain or six hours after the vehicle has been locked. Operating requirements ▷ It must be possible for rain to reach the touch control box in the area of the rear-view mirror. The touch control box may be obscured by a car port or bridge, for example. ▷ Vehicle must be in rest state. ▷ The function must be activated in the settings. |

I've coded my Pre-LCI (2017) with the instructions, and rain closing does work, but I'm trying to figure out how to extend the time the sunroof stays open before it auto closes. I'm assuming that the StatusRCTime variable is for the time delay for closing, since the "default" is "06" and the IDrive menu shows that it will automatically close in 6 hours.
I've tried setting this parameter to Not-Active, and to custom variables like 09, or even 0C (hex for 12) hoping I could extend the time, but it seems like the module just ignores anything that's in StatusRCTime, as my sunroof still closes after about 6 hours. Anyone successfully been able to extend the time beyond 6 hours, and if so, what setting did you do? Maybe I need to update the software on the FDZ2 module? |
