e89 roof problem

Post by Ole gits rule » Mon Jul 26, 2021 2:29 pm

Car is in the garage, called the warranty company and told to take it to a VAT registered garage - roof is covered.

Guy had a quick look and said microswitch or hall sensor so a case of him running a full diagnostic and getting it fitted

Hall sensor would be wrong.
Could you post a first diagnostic result to verify?

He did a quick diagnostic and said it was showing hall and microswitch errors but that was a 5 min job when I was there.

Will post when I know exactly what is up with it :thumbsup:

I would not trust the checks 50%.
When my relays played up it said 5 sensors or limit switches were faulty.
When in fact only relay was faulty.

I have told the guy that I think the issue is the microswitches - he is an ex BMW mastertech so I hope he knows what he is doing :!:

Me to dude - should have some info this morning, he will do an hour diagnostic and then stop and call me as after that he needs my approval to continue but I have told him its 95% certain its microswitches.

Microswitch coupling lock on both sides of the hydraulic rams in the boot. Not the microswitches in the roof shell!

Car back and sorted, microswitches was the issue and it was the ones Robbie said.

Covered under warranty apart from £50 which I am happy to pay as any issues and back to the garage. :thumbsup:

    Yep, was £35 for the switches so for £15 I am happy to let some else mess with it.

    Especially when I collected it and the roof would not budge, took them 45mins of messing to get it to go, they had to move the switch.

    Congrats!
    The problem is, that in most cases the faulty switch can't be measured with an ohm meter. The MS are not broken, but their timing doesn't fit anymore to the allowed tolerances.
    One day it works fine, the other day the roof stops anywhere.

    I am not trying to be difficult, honestly, but I don't understand why that would be Robbie? As I understand it the bootlid ram microswitches are not functional until the last part of the bootlid (trunklid) cams pull the panel down and so momentarily make the switches. Why would this have a bearing on the whole process stopping randomly?
    Also, why would an ohm-meter be useful to determine the operation of a switch? A continuity tester, I can see.
    I am genuinely interested to gain more knowledge into how the process works, as I have a reasonable knowledge of electro-mechanics but know nothing about electronics.
    All good things come to those who wait. I'm really impatient which explains a lot.

    That is what happened to me, worked force when I went out but played up when I came back - sodding pain as I do not have a garage but my neighbour does so I parked in there overnight as the windows were down
