Just joined the rush. Sopers in Lincoln give Forum members 10%. Ordered ten minutes ago. Collect tomorrow..
Thanks for the heads up to Smartbear and RobbiZ4.

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?

Does the bong happen when you operate the roof on the move?

Just totally random ....it hasnt bonged for ages...i went to Wells yesterday morning and it was fine...coming home it just kept bonging
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

micro switches "Koppelverschluss" in the compartment
For the latter I have to check the English name.

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.

PartNo:
54377228585 Microswitch kinematics box left Z4 (54377228585)
54377228586 Microswitch kinematics box right Z4 (54377228586)

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?
