Ok, thank you! I will order the parts later this week and fit them straight away. I am all for simple, preventative maintenance.
E89 roof relay change

- Start date
Attleborough, Norfolk
I'd go further and say get rid of any metal objects in the boot first!RobbiZ4 said:
Hell, even an umbrella falling across the battery could ruin your day if it bridges the terminals with a metal part.
I actually have an old piece of rubber floor mat that I lay across the top of the battery on any car I'm tinkering with.
After welding a spanner to the wing of an old Capri I learned the hard way. :roll:

Maybe including where to buy and what spec of part?
Just a thought...
Hi Craig,
I’ll link the ones I ordered off eBay here

As far as fitting them I can repost pictures when I have time but I found it very straightforward a 5 minute job
Remove boot carpet
Remove Foam
Reach down to the top relay & unclip
Reach down to the bottom relay & unclip
I made sure I made a note of how they had come out (which side was facing upwards)
Then refitted them, bottom one first
They only fit one way round.
But why do they fail?
Tested on a bench they work fine.
Is the control module detecting a coil fault.
This is why my Foxwell reader said there was a fault. How else could it know there is a fault?
Are coil open circuit resistor in relay breaking down changing resistance?

Cheaper from dealer £16.
But of course takes petrol money to drive to dealer.

What should be easier than a BMW part number and a photo? Should I settle over to UK as resident and post it once more?craigdm said:Is there not an easier to follow UK guide to replacing these?

Just read the basics in my linked thread on ZRoadster or even Spoolstreet. It's well explained.flybobbie said:
It's NOT a simple fail of a relay. It's experience and the result of investigating lot's of destroyed hydraulic pumps.
At least, it's a welded relay contact, that can't be opened anymore. This will drive the pumps motor continously until it dies due to overheating.

If you live miles away from a BMW dealer they will post them out to you for £2, personally I would prefer to buy these from a dealer than Ebay and RobbiZ4 yes please relocate to the UK, Im sure we could keep you busy especially as the E89 gets older!flybobbie said:
I’ve just discovered this thread… our car is 2010. Don’t have an issue but don’t want one either! So going to place an order and get them swapped out as preventative maintenance. Thanks guys. A
Update: ordered this morning with Soper BMW Lincoln. They still offer Z4 Forum discount and cost me £30.46 the pair. Part number is same : 12 63 1742 690.
A Little January preventative maintenance: I read elsewhere in this thread not to use screwdrivers! I just need to find the black clip and slide out the assembly to easier access the relays….
