Roof open -after replacing the sensors

[Coffee-van]

Hi!

I’ve got a 2005 t5 with the hydraulic elevating roof

I had a leak in both pistons and a cracked hose on left side on the car. Replaced both pistons and hoses on left side. 4 new position sensors from bmw were also fitted

Still the car think the roof is open. Hence I’m not able to open it from the panne ( i had to hoook the motor on to a battery to get the roof open)

Any ideas on how to get this sorted?

When i elevate the roof by batteri, the controlpanel works as intended intim i close the roof. Then it wont open again

Note: i might have mixed the two sensors front/rear on left side while replacing the piston. Is there any wiring scheme available? I suppose the wiring colour will tell front/rear.

Headliner is out at the moment, so i could theoretically measure the cable loom

further investigations:

Fault codes as follows: 1000, 1001, 1010, 1011

Attached is a snap from the manual. Position sensors is marked 1-4

I don’t think it’s possible to mix the two sensors (front/rear)…? They have different length to the wires, right? With the roof closed, have you tried to delete fault codes stored in the control panel? Have you tried to press and hold lower right button for at least 5 seconds? Have you tried to restart the control panel? Have you tried to disconnect the two leisure batteries for 5 minutes?

If you have another California, a friend, you can compare components and wires I guess…to confirm you done it right?

Hi

I have tried deleting the codes. 1000 and 1010 comes back

I havent tried to disconnect the two batteries. Any spesifikt way to restart the panel?

My cable buam had the connection in the middle of the piston - fully plausible to mix front and rear

1010 Short-circuit to (earth) roof.
Maybe you should try to swap place for those front/rear sensor?
Also sjekk for damage wires. They are pretty thin and fragile..

I would check they are connected the correct way around. With me it was brown and red wires to brown and red. Did you do it yourself? There is no difference with the 4 sensors front or rear, left or right.

Those codes suggest they’re not functioning. When I fitted mine there was a correct way to fit the rear ones I think that was possible to get wrong. See instructions

How to Replace Roof Sensors

My roof has over the years occasionally said it was up when it was down. I‘ve owned it from 2009 and know the sound it makes when closing so have ignored this. I think last summer this finally became worse. Coincidentally after last summer I decided I wanted to replace the control unit as the...

Update:

The problem is now sorted.no more codes!
I swapped the signals (red/yellow wire) for the left side on the ecu and it worked. Swapped the wires back and then shifted front/rear sensor. All ok now

Info:
Cable Colours:
Left side:
Brown-yellow= front
Brown-red-read

Right side:
Black-yellow=front
Black-red=rear

BMW position-sensors works ok
Pistons for roof from JP-group works ok


Only thing remaining is to find an alternative oil for the hydraulic roof system

As for connecting the sensors, these heat shrink soldier tubes is handy
