Roof motor brought back to life and relocated into boot, WITHOUT REMOVING ROOF! with pics.

Postby Ducklakeview » Sun Apr 03, 2016 9:19 pm

So first tasks of the day;

Get roof motor out without removing roof, or any interior trim

Try and bring motor back to life, as it stopped working a few days ago, although was fine when I bought car.

Relocate to boot.

Time permitting, fit GapTech RCH+ module.

So, I reckoned there was no need to remove any interior trim.

Removed shelf under hood storage area, and also the left hand mount for same (one 10mm bolt, one torx screw and one plastic rivet)

Could then see the motor :)

Image



Started to give it a good push/pull and then I heard water, climbs out of boot for about the 10th of 100 times, and sees this under car..

Image
That's the drain unblocked then...


It was not budging, so in the end I used a 10" prybar down the back of it, and managed to engage it on the lip between the two halves, it soon came free

Image


I then lifted it out, after cutting a few cable ties, and lay it on it's side to drain...

Image


Housing had clearly been wet for some time.

Image


And the insulation was like a wet sponge, silly idea.

Image


Hmm..

Image


Why they don't wrap them in a sealed bag I do not know, instead of this stuff.

Image


IT would help prevent this!

Image


I feared the worst for the motor

Image


And the other side was worse.

Image


Removed the motor and gave it a clean, some WD40 and a nice ultrasonic bath in deionised water, before putting it into the oven at 90 degrees for 20 mins.. Took it out and tested - It worked like a charm :) Reassembled and tested - All good!

Image


I decided to use a shampoo bottle to protect the motor and connections, I also washed and dried the original pad from the bottom, and the motor insulation wrap, before gaffer taping that to to the bottle, no pic of the refitted insulation.

Image


Made a small cut into the plastic of the shelf mount, to pass the cables through, and refitted it all. Carpet could do with a little more fettling, but I was in a rush to get out, so just used some spray adhesive for now, as I'm going to have to top up the oil I think. The white is the adhesive drying.

Image


GapTech module fitted by soldering, and all good - So off out for a play!!

I think the oil level is low, as when opening the roof, it needs a hand to get it moving, but closing is perfect. Does anyone know the top up procedure, ie which way up should the motor be held, and is it done with roof up or down?

Hope this helps people, took me about 3hrs all in, and save me a good few ££!!

I can modify your exhaust and make it sound AWESOME, see here; viewtopic.php?f=2&t=89154 I can also put your roof motor in the boot WITHOUT removing the roof, in under an hour.

Great job. The less £££ BMW get from us for their shoddy engineering the better!

Excellent Job. well done.

Mark the fluid level then cycle the roof. Watch if the level is highest or lowest with the roof up or down and then only top it up from the highest mark, otherwise it will overflow if you top it from the lowest point, when you cycle the roof.

I take it the fluid reservoir needs to be at the top to feed the pump? If so, do you then invert it, remove the circlip and reservoir and top up?

Just had a thought, after reading a couple of threads. I wonder if my bowden cable is partially seized at the pump end, causing the slow opening, thinking about it, if it was low on fluid, then surely it wouldn't close properly, as the reservoir would run out as the fluid moved into the extending rams... I think I'll check that tomorrow, seeing as I can now access the whole assembly in seconds :)

Leave the resevoir at the top, motor below. Undo the fat grub screw on the top and pour a drop in gently. :thumbsup:

Grub screw? Didn't notice one, I take it that it's on the pump body?

Really good work and very useful to know this can be done without removing the roof. :thumbsup:

Question - when you removed the motor did you have to disturb the hydraulic lines at all , or can the motor "cylinder" be removed from the bulky square section and oil reservoir that houses the hydraulics without complications?

Also can you elaborate on "ultrasonic bath in deionised water" - what is this?? :?

There is a large earth connection just behind the carpet in that area, the stud was long enough for me to fit a cable tie base and another nut, the motor is held to it with 2 thick cable ties.
