Roof issue

[RobbiZ4]

Perfect and respect, it's been a long way (or day ).

As a matter of fact. But you could also tackle the remediation before the first roof problem occurs. The broken wires will hit every e89.

Why not now?

Robbie, do you suspect the wire issue is primarily down to ageing (the wires get old and brittle perhaps) or more related to a certain amount of cycles of roof operation?

Morning,
I'd say both causes in combination.
If the roof is not used at all from day one, after 20 years the cables can break on the first try.

If you are an intensive user on a daily basis, these issues will start already after 5 years (yes, I already had to care about a 2016 E89).

Let's say it's a structural weakness of this design. The hydraulic wire harness is bent in an arc with a too small radius.

From my experience an average usage seems to be about 300 roof cycles per year. That makes about 3k in 10 years with the results we currently can see or read.

In beetween, I've placed an electronic counter next to my hydraulic pump to get a better overview of my roof cycles.

Wow. 300 cycles per annum? I doubt I drive the Zed 150 times per annum, and I’m lucky if I open the roof 20 times per annum.

... I open the roof 20 times per annum.

But if you live in a city like us, you will never park it with the roof open. So it will open up to 10 times on a sunny day.

Not sure how old this thread is, (odd that the site does not include the posting date for each post. Most sites do. This would be very helpful) but is still pertinent. I believe a microswitch is bad, indicating that the boot is not secure. I disconnected the offending switch to trouble shoot. Night came, so I closed the boot, and the roof is full up. The issue now is that the boot will not open, and the roof will not open. I attempted to jump pin 12 at the junction box, and can hear the boot lock activating, but the boot will not open. I hit pin 12 multiple times, and each time I can hear it, but when I go to open it, the latch moves, but the boot is still locked.

Any ideas where I go from here?


FYI> reading to codes, the left switch showed open and the right closed. Now, the left is disconnected, but the code shows it as open

You're fine. It's 2 days since the previous post.

Go into your profile and change the settings to show dates. It, for some reason, seems to default to not showing dates and times.

Get one person to do the wire shorting and another to open as they hear the motors.
I came across similar problem once where i had to "catch it" just in time.

It's been a year and 2 days.
The date of the posts should be between the posters details and what they posted.

Oh yes, so it has. I need another trip to Specsavers!
