A few weeks ago I tried out my sun roof and it reluctantly worked after a couple of tries, now when I try and open it the windows go down but nothing else happens, does anyone have any ideas could it be the motor and is it an expensive repair?

Yes I'll probably do that, I've just mov3d house so I need to find a local BMW specialist....
Well I have found out today that it is the pump and motor that have gone due to water ingress and the cost of a replacement part is over 2.6K, this is from a local specialist as well not a dealer.Chippie said:
I have found the part I need on ebay for just under 1k. However, I was wondering if the motor/pump used in another bmw model would fit as they seem much cheaper

Sure I saw these motors being sold as rebuilt units on ebay for something like £400?
Just checked - search e89 roof motor & there are tons available from reputable sellers. Are you certain you need the pump as well as the motor?
This is not as bad as you think.

That's what they told me in the garage, I have emailed them to double check but they did say motor and pump were damaged :?matsmith749 said:

Well at that cost, I think I may be going somewhere else for a second opinion.

The cost is correct unfortunately, I got a price from bmw as well with a similar shock..... :?

Not on the cost but the diagnosis, if I was going to spend anywhere near that I would want to be 100% certain it was going to fix the issue
I agree but there was water in the bottom of the boot where the motor is so it all seems to make sense sadly

Well thats the motor - is it certain you need a pump?
I am no expert so can only go by what they are telling me. I've messaged the garage to ask them if it is definitely both the motor and pump. I've actually found a motor and pump on ebay for £579 so bought that and will see if I can get someone to fit it for me
Definitely will check it out many thanks 
Should there be any kind of roof drains that I need to look for in case they need unblocking as well do you know?Chippie said:

There are no drainage channels to unblock, the problem is how the water runs around the rear and sides of boot, you need to check the condition of the rubber seal around the top edge of the boot, BMW use a sealant that dries out and turns to power letting water past, also it’s quite a common problem for the rubber seal around the back lights not being fitted correctly, you need to make sure that it is sitting either side of the body work and not on only one side as water is channeled over the rear lights to drain away.
