BMW Z4 2011 - Roof won’t close properly.

Hello All.

New to the forum. In short my BMW Z4 roof has opened and gone through the full sequence successfully.

I’ve then gone to close it, and it starts the closing sequence. The boot opens. The roof comes up and then the second part of the roof (the windscreen section) won’t lower. I can hear a motor going in the boot area but nothing happens.

It says on the fault system (on the screen in the middle of my car) that it’s not latched properly.

Any ideas? I’m hoping it’s not an expensive fix but I fear the worst!!

Thanks for reading.
 
Don't mean to be negative - but from my 10 years on here, found that most BMW specialists are absolutely hopeless (& expensive) with the roof!

A cheap code scanner is going to tell you the fault - almost certainly one of 3 things:

(i) Broken wire somewhere in the harness
(ii) Failed hall sensor, usually on the rear struts
(iii) Failed microswitch (there are a few on the mechanism)

The 2 most likely (hall sensor / microswitch) are £50 DIY fixes, with all the help you could ask for available on here.

I understand the 'take it to the garage' route (I do it myself), but for the roof it's very problematic.

Their problem is, that there is no internal documentation available how to correctly diagnose a defective roof. Without identifying the root cause, most of them just guess around.

I recommend the BimmerLink as app solution. There are others on the market, Carly offers annual subscriptions.

These prices have changed since spring.
 
Sound markedly similar to my issue as on this thread. Fixed with microswitches but as @RobbiZ4 says - you are now looking at least around £130.00 per side for these.

I dread to think what an indie would charge for this sort of fix and that's presuming they can even correctly diagnose it in the first place.

Pretty sure that one of the 2 coupling microswitches is the source of this issue. As written in my list of recommendations, both have to be replaced in time by new ones. Unfortunately the price raised from 17€ up to 150€ each in the last couple of years.
