This thread is suggesting 'Not to worry if your roof motor fails' - FALSE!

From my own experiences and other forum members and Z4 owners i know its not as straight forward, and the Almost 100% records being touted about are more like 70-30.

Yes there are some great examples of heavily corroded motors being rejuvenated, but theres plenty that are not salvageable especially if the small internal circuit board becomes corroded.

Ive had my motor relocated by a forum member, and i am very happy with the job, but the motor was f@$ked, so i purchased a reconditioned one from www.roofmotors.co.uk for £170.

Obviously i am now going to get told other wise, but i think its irresponsible to inform new forum members there virtually always fixable.

Sorry, but I disagree. I have done in excess of 150 repairs/relocations, and have seen some very sorry motors. Corroded circuit boards with broken tracks, brush leads turned to powder and capacitors fallen to bits. WITHOUT EXCEPTION, I have repaired EVERY one. Some take longer than others, especially where the brush leads have rotted away, but they have all been successfully repaired by me. Without mentioning names, there is even another member on here that relocates motors, and has actually sent some to me for repair as they couldn't get them going, again all of those were returned working to them.

So I think in fact, that I am pretty well placed to be able to say that I can repair them, because my record IS 100%.

Well I personally can't boast the same success record as Mike (DLV).

I'd say I've probably done about 20-25 motors and have had 2 that wouldn't spin at all and 2 that would only spin intermittently without needing a helping hand. (Worn bushes meaning it depended where they stopped as to whether they'd start again unaided)

Therefore my success rate on reviving rusty motors is probably about 85%

Some will go but I don't know if the owners have then had to change them subsequently, which is easier once they are accessible. I'm sure some will work repeatedly immediately after some TLC and relocation when they leave me, but try them again after standing still a week or two and they may not be so reliable.

The whole point of moving it is to future protect it but also to make it accessible if it does need changing at any point there on.

It's corrosion on the commutator that causes them to work intermittently. Left in water over winter etc, it builds up, but not so much where the brushes actually rest against it, so if it stops with the brushes on the clean section, it will start again. Telltale is if it spins into life when the shaft is rotated by hand with power applied.

I strip EVERY failed motor and clean them up properly, so they continue to work.

My roof motor problem is now sorted, in my haste to get the roof down with a non operational motor, it jammed and in a fit of childish rage I pushed it too hard and with a loud pop and a mist of hydraulic fluid, I now have a sheared hydraulic line.
The plus side is once I push the button to release the hood all I have to do is gently tug the top and it falls down and stows itself, putting it up is just a release the catch and push the roof up, 10 second job, downside is I have a swimming pool of hydraulic fluid stuck in the motor stowage as well as the water....

Do you know which hose it is, they are numbered 10,11,12 and 13 just near the banjo connectors on the pump. I can replace any of them, even 11 without removing the whole roof. The hoses can be bought for around £60 each from https://www.cabriolet-roof-hoses.com

Is there a guide on how to clear the drains? I did this on my old MX5 and lots of water poured out!

Many thanks to No.5
He rejuvenated my soaked motor and relocated it to the boot and all is working fine now


I would defintiely recommend him

I cleaned my drains and water came out, but when the motor was moved to the boot, it was still sat in a pool of mucky water/slime.
Just a stupid place to put the motor in the first place.
