Question Comfort Access - tailgate/hatch won't open when pressing pad on rear hatch

2013 X1 MSport

The hatch opens, pressing the pad on the hatch IF the car is unlocked - it also opens (unlocks) if I use the FOB button or the button inside the vehicle. BUT if the car is locked and I am standing at the rear hatch with the FOB (new FOB batteries recently installed) pressing and holding the pad on the hatch exterior won't unlatch (open) the tailgate. The pressure switchpad functions 'correctly' to open the hatch if the car is unlocked.

I'm suspecting the touchpad/switch on the rear hatch has failed - no matter how hard I press or how long I hold it the hatch/tailgate doesn't unlatch and I have to use the FOB to unlock-open the rear hatch/tailgate.

Has anyone experienced this? Anyone replaced the switchpad? Or the CA unit at on the hatch/tailgate?? Looking at the TIS makes it look like an easy DIY and the part is available on-line of less than $40 but if it's something that can be done by reinitializing the FOBs or if it requires replacement of Comfort Access modules that would be something to rethink.

ALL other CA functions are OK! No RF interference going on - I've tested this and used the hatch access without issue as long as we've owned the X1.

I had read there was a process using the key to unlock the car front door - start the car - etc ... but didn't have the opp'ty to try it. BUT I just tried your recommendation and the tailgate now unlocks, as it had previously, with the FOB.
Thanks for the tip :-)

Thanks for the advice; I've had CA on my BMWs going way back to my e60 2007 530xi and never had a FOB issue.

But as the old saying goes, "There's always a first time!" ... so I guess this was mine :-)

Thanks again!

Doesn't inserting the key also charge the key battery?

Not on the CA system. It has a replaceable battery. Non-CA systems charge a key fob.

Rear hatch acting up again - opens OK with CA if the X1 is unlocked but not separately when the X1 is locked. I'll double check the FOB batteries to see if they're at full voltage but I did replace the batteries about a year ago. It's not a big deal to unlock the car to unlock the car (using CA) open the hatch so I don't think it's a mechanical issue. I did use the FOB inserted in the slot to start & restart it 2x but that didn't resolve the problem. More later after I check/replace FOB batteries.

UPDATE: Replaced FOB batteries ... rear hatch w/CA back in working order.
