Guys,
My electrician has replaced the sensors and it seems like the main problem is the Combination control module, which i believe is also known as the main computer or brain. Please can anyone guide me to a spare one. I live in the UK.

Cheers

Are we talking about the fuse box, the ECU or something else?

If it is the ECU it is vin coded to the car it came from and you can not just go purchase a used one and plug it in.

This place in the UK fixes ECU for about 5% of the cost of a new one.

Thanks
The mercedes Error log say its definitely CCM 1708200926 so it cant be the ECU. as all other systems are ok.The problem is to do with the roof and all other components thats associated only with the roof.

see the error below
The errors are
ECU MBnumber Result
CCM- 1708200926 Failed
Vario Roof 1708200926 Failed
PSE 1708000548 Failed

For the roof the code are

switch is operated for more than 25 s or cable has

2. B1010 : The supply Voltage of the control unit is
too low (under voltage)
3. B1270: component s69 /9 ( trunk lid open limit
switch) and S69/7 (left trunk lid closed/Locked limit
switch) or components s69/9 ( trunk lid open limit
switch) and S69/8 (right trunk lid closed/locked limit
switch) are operated at the same time
4. B1272: implausible signals from components s69/1 (
vario roof closed limit switch( right lug))S, 69/2 (
vario roof locked limit switch( right
rotarytumbler))s69/3 (vario roof locked limit switch (
left rotary tumbler and S69/11 ( vario roof raised
/lowered limit switch)
5. B1273 : implausible signals from components s69/1 (

left trunk lid closed/locked limit switch)S69/8 (right

6. B1274 : No limit switch signal
And finally
