Sun Roof Not Working

optimistique1 · Post by **optimistique1** » Sat Mar 16, 2024 10:57 pm

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?

It’s could be anything from a faulty sensor/micro switch to a broken wire, you would be better off trying a fault code scanner on it or taking it to your local garage for a diagnosis.

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.
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

Sorry to hear that, I think I’ve read that a pump from an Audi A4 is the same, but you would have to check to make sure it’s correct.

There's several users on on here able to revive and relocate the existing motor,
For a fraction to the costs

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

You may be thinking E85?

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
