Hey

Where i can find roof motor hydraulic unit without motor? Just buy new motor but also this unit is broken
Do you mean the pump that the motor fits too, or the hydraulic lifter rams on the hinges?

Where that pump fits
The square unit with the fluid reservoir on top of the motor?

OK, those are really hard to find. You may have to look for a complete unit, including the motor as they very rarely come up for sale on their own.
What are thre symptoms that make you think it is the pump that is faulty?

Idont have picture right now, but when is was put new motor back to that unit, there is bearing ring outside of that housing, (didnt see that coming out it place) that wedged in and could not get out without damage. Sorry i dont know how to descripe that in english properly, but tomorrow i add picture. So i broke that by myself that is symptom. I allready ordered used part witch include all even the hoses. Ebay was 3 unit with decent price. New is nearly 1000€
 
Last year I bought a whole new original unit for 546€ at some official BMW dealer. But there are no hoses included.

My old unit has the electric part burned out but the pump looks like new, there is no rust anywhere. I have no idea though, why the motor burned, there was no water present inside the housing. This was the second unit for my Z4 however and after the first replacement the housing was perfectly water sealed.
