Hi many thanks to you all for reccomending Mike. I have made the 400miles round trip from London in one day few days ago and met the most knowledgeable and charming caracther who without a fuss set himself inside the boot of my Z4 and removed, repaired and re houses the roof motor within an hour.
Yep , i can confirm that Mike is definitely a contortionist as removing the motor requires some proper skills but he definitely know what he is doing.
Not the same can be said for the “ expert technician “at BMW where I took my car few years ago to have the same problem resolved. Four days and £ 1,200 later, look how they have “ expertly “ solved the water ingress problem.
Silicon and electrical tape. Shocking !
If you have the misfortune of experiencing roof motor failure take the trip up north.It is well worth it!
