2003 BMW Z4 Convertible Top Hydraulic Pump Motor Replacement. pt 2 

Good luck it's not a pleasant job...

Wish I was there right now. It's-30c here now...

@@PhillipBailey here it's +23C 02am ... Just came back from a night ride with the top open

@@abdolf sweet!

It's actually much easier than this. Everyone I know relocates the pump to the trunk without removing the top. I've done a few myself. It takes about 45 mins to pull from the side well.

I thought about that but did put a couple of extra drain holes in the bottom of the B pillar are to better drain the water. I also advised the customer not to allow leaves to build up on the car.

That's possible if the main motor in the b pillar behind the driver door is running but the top does not move. The cable pulls on a small pivot that opens a relief valve in the hydraulics to allow the top be opened or closed manually. If you can push the top open after its unlatched the the release is likely stuck. Make sure the cable in the trunk is not pulled out and try to manually push it in. If that does not work unfortunately the entire roof must come off to service anything at the motor/pump. I've seen a couple videos where people access it from inside the trunk but in my opinion that is a huge hack job as the pump/motor is covered with a plastic housing. good luck...

@@PhillipBailey on the arm of the roof?

@@nickanning Not sure what you are asking. The release cable is in the trunk by the left trunk hinge under the back window.

@@PhillipBailey sorry I’m not being clear - I’ve found the release cable and haven’t been able to push it in so I think that it may be broken/corroded/no longer attached to the cable. Presumably if I take the roof off I can find the lever it’s attached to and put this in the correct position so that the hydraulic system is re-engaged, and the roof will start working again? I’ll let you know tomorrow if I have any luck!

@@nickanning I believe you have to twist it 90 degrees to unlock it...

Ordered from a BMW dealer out of Toronto.

I am still in business but am located just outside of Thunder Bay in Ontario Canada. If that works for you email is phils@tbaytel.net.

Yes was a fun job for sure.

I did mine in about 45 min wihtout removing the top.

@@tim-hill Did you?… have you any useful tips/links? I’m about to attack mine this weekend coming 🥴

I believe it can be manually opened. There is a release cable in the trunk near the left hinge that needs to be pulled and a mechanical release above the mirror. Should be information in the owners manual.

That seems pretty steep to me. Is that USD as well? Parts retail here for around $950 Canadian. It's around a 5 to 6 hour job. I think you should shop around. It is a PITA job and at some point requires two people to lift the top on and off. Where are you located?

This job cost my customer $1950.00 parts, labor and 13% tax. That was a genuine BMW part and Canadian dollars.

It’s been 11 months but JIC; I did it by myself in 3 hours and I didn’t have to take off the top! You can get to it through the trunk! (: I found a cheaper part through eBay w all wires included and relocated my motor to the trunk so it wouldn’t drown in water in the original location. If it got clogged once from all the gunk, it’s going to happen again and drown the pump again. Everything cost me $180 USD. Meanwhile I waited for my part to arrive I disconnected everything so I can put my top down manually.. hope this helps.

@@SpicyTamalehi do you a video doing the job?
