E89 Roof goes up and down on interior buttons but not on fob?
Posted: Sat Mar 23, 2024 6:39 pm
So bit of a weird one..roof goes up and down on interior buttons..with or without engine running..
Using comfort access key fob you can lock the car / fold mirrors /close windows..you can unlock the car / mirrors..
You can release the boot.
But you can’t open or close the roof on the fob.
Salient points are
Gen 3 Mr 12 Volt MMI box fitted
ID4Motion digital cluster fitted
Only error is a long standing comfort access door handle error which has been there since I acquired the car and previously didn’t stop the roof opening or closing on the fob..
If you’re in the car and try and open / close on the fob you can hear relays clicking but no movement and a red light momentarily appears on the roof button..but after the first attempt the red light doesn’t re-appear.
Scanned the car and no other errors shown,,this is after 200 miles of driving so everything warm and battery fully charged.
Whilst twiddling over the winter power was repeatedly disconnected and reconnected many times.
Any ideas ?
