"Check Control" error message on the display?

if you have no airbag on passenger side (RHD). Open the glove box, there is a plastic piece/cover towards the side of the BC. Remove the M 10 (?) screw, the cover moves down a bit. Now you can reach to the back of the BC thru a small slot there and you can push the BC or move the lever to open position.
That is how it works on the E32, not many people know this trick. All remove the radio first.
Give it a try, maybe it works on the E34 too. Easy and time saving.
This pic is from a LHD, so it should be easier to do it on an LHD car, as the lever is easier to reach


But I have a lot of space, cause my audio part is in the trunk and the operating panel in the dash is very short. Rear panel in the armrest between the rear seats has the same size

yeah as an update, we replaced the obc and all is well
upon further inspection the orignal obc must have shorted out
or gotten the cleaning fluid on it some how...

all is well =] and it smells great too =]
