Thanks!... wow that looks intimidating!
so replacing an hydrolic 'loom' is replacing the hydrolic lines? Why? is this because the lines go bad? how?(and would it help to treat them to prevent that?) sorry for any dumb questions!

The hydraulic lines as well as the wires to the different sensors in th rear roof shell get weak over the years and finaly will break. Wires can be repaired for a while, but the hydraulic lines will break and can't be repaired.
Done.
Well done. Thank you.
Well... I should not have said anything... my December 2015 Z4 is now in the garage to have 4 hydrolic lines replaced. A few weeks ago I noticed that hydrolic oil was leaking from the passenger side... I've got a good indy that could source 4 new lines here (in NL) https://cabriotech.nl (replacing a bunch at once, so that we prevent the same thing happening later to a loom that has endured similar strains)
Well, IMHO it does not make any sense to only replace the 4 hydraulic hoses, as the 2x2 +1x2 wires to the sensors/switches will break as well. The whole hydraulic harness should be replaced to be safe for the next let's say 8 to 10 years. And it's much less work to only mount a new hydraulic harness insted ofpeng wrote: ↑Wed Nov 03, 2021 11:20 pmWell...

while we are at it all the microswitches are replaced also. (Since the roof is being disassembled now anyway)
Frankly... I'm a bit pissed off at BMW... the car has only done 60K and is 6 years old... this should not be possible! Looks like this will be an expensive repair...
I still think I'm lucky that my BMW guy wants to take this on though, most 'specialists' don't want anything to do with the convertible roof was my experience with my E46 cabrio, which ALSO gave me (expensive) roof problems

Quite scary though, mine's 09 with 40k on it and seems like it's just a matter of time ffs.
Anyway, is there a diagram/drawing available so I can get a feel for where the hoses, cables and switches run please?
Well..... looks like you were right... Fixing the hydraulics turned out to be quite a challenge, even though the lines were fine we needed to source the exact right kind or O rings (oil proof, right size etc.) which turned out to be quite a hassle! Because of this the repair took a long time, and my guy made sure to replace the switches while he was at it... It's a good thing I'm mostly working from home (for now...)RobbiZ4 wrote: ↑Thu Nov 04, 2021 12:15 pmWell, IMHO it does not make any sense to only replace the 4 hydraulic hoses, as the 2x2 +1x2 wires to the sensors/switches will break as well.

- dismounting the old hydraulic harness
- stripping the old hydraulic hoses off the harness
- organice 4 new hydraulic hoses
- integrate the 4 new hydraulic hoses into the old harness
As the whole hydraulic harness is taped and fixed with zip ties, this nonsense steps take too much time and arises the risk for a next issue.
I've been in the Netherlands last Sunday, so it's a pity to not get informed or contacted before.
Phew, what a story.
Which ones exactly? There are 5 microswitches mounted in the roof.
