When you say rubber cover do you mean the rubber passenger door window seal or something else?the plastic container the motor is in is fixed to the hood hinge with a cable tie & a small tang if you stand by the passenger door & remove the rubber cover & with a long knife cut the cable tie & the plastic side piece the whole lot comes out in one piece.
I lacked the confidence to rip out the housing so I gritted my teeth and took the car to a repairer instead. In some ways it was a good thing that I did because after he took the roof off he discovered that the motor/pump assembly was in fact ok, it's the left hinge/ram that's leaking. Unfortunately the hinges are even more expensive than the motor/pump assembly so instead of buying one replacement I intend to have them both rebuilt.Appoooh, did you manage to get sorted?
What year is your wifes Z4? Also is the plastic casing to large to fit behind the carpet if I was to refit the motor and pump back into the case after relocation?and most importantly have a beer, knowing that it will no longer get wet, It is easy to get to, and top up if required.
Over 2 grand to fix from BMW,
I did it for free.
Do you by any chance know the part number for the motor you replaced?Glad to help. Several weeks ago I decided to tackle my dead top motor and it was quite the project. I was determined to complete the repair through the boot alone, however the previous owner had gone nuts with zip ties so I ended up having to unbolt the rear section of top to access the pump/motor assembly. Once removed, I tried all the usual tricks to revive the motor but it was toast so I decided to replace it. But after pricing new oem, I followed a tip (thanks YouTube poster) and purchased a used (with warranty) 2014 Ford Mustang pump/motor from a seller on eBay. There are lots of them on there cheap, and model years 2008-2014 will work.
The Mustang unit is the same German manufacturer as the oem BMW, but the Mustang's is at least 25% larger. It is virtually plug and play as the hydraulic lines swap right over, as does the shorter BMW oil reservoir which I needed for clearance in its new location. I mounted the assembly vertically by zip-tying it to an L bracket I mounted with a self tapping screw in a corner of the boot. I then wrapped the motor/pump in a section of grey split foam plumbing insulation, which matches the oem carpet quite well. And..done.
The result? The top operates at warp speed now, and is super quiet. I can top up and bleed the hydraulics in place, and access is two snips of a zip tie. I encourage anyone reading this to consider this upgrade for your Zed, you will be a happy camper. View attachment 93069 View attachment 93070
