Well here's another one that's jumped on the band wagon and ordered a pair :wink:
E89 roof relay change
- Thread starter Smartbear
- Start date
Scotland 🏴
Yep did mine too over the Christmas break as a preventative measure. So quick and simple to change over. Maybe we should start a poll to see how many E89 owners have now done a salmon relay swap based on the advice from RobbiZ4?
I swaped mine out today, the ones i took out were only 18 months old so ermmm i may have a pair for sale hahha
i still get a stupid random bong .....i thought i had fixed it 3 months ago and its been fine...
Went out yesterday it started up again....i havent had the top down in between....its a mystery

Just totally random ....it hasnt bonged for ages...i went to Wells yesterday morning and it was fine...coming home it just kept bongingSmartbear said:
i Havent touched the roof controls for ages.
I swaped the relays today, when i went to test it....i had an odd bong, and the roof movement impaired message...then it clears and everything is fine again
The top goes up and down fine, not slow or jerky, and the windows come up.
Its a bit of a mystery...

There are two potential causes:
- broken wires in the roof
For the latter I have to check the English name.
- micro switches "Koppelverschluss" in the compartment
That is another of my 6 recommendations in the German ZRoadster forum:
replace both micro switches every 10 years.
There is a small spring on each micro switch, that is streched permanently. It gets weak over the years and leads to random states of these switches, often while driving over small bumpers or other road issues. Sometimes the switch may even "hang" and from the CTMs view, the lid is not locked.

Takes about one hour to replace both - once you have seen how to.
I see the eccentric cam in the newtis link that pulls down the bootlid, do you put anything on it to reduce the creaking sound they can make? :?

I bet you wished you’d never asked now! :roll:

couldn't replacing the micro switches wait till they start producing the symptom?

RobbiZ4 said:Well, that depends.
Each symptom will pop up in the most worse situation you can ever think about. Murphy will be your passenger.
The CTM will cry for help, no roof movement anymore, the windows can't be closed, it will end in a nightmare far away from home. Special here near the alps, it will hit you on the mountains when the rain is coming up.
That is the the same with all the other maintenance tasks: battery, micro switches, looms, relais, ...
Not sure this was answered earlier but no need to isolate anything? No battery disconnect required?
Did any of you guys "pretest" the relays first in case you were replacing an old (but working) one with a duffer... ? Or am I far too paranoid... :roll:
