2016 E Class Cabrio - Hydraulic pump release valve
The release valve (circled in red) I lossened it off to manually raise the roof
when it got stuck open. I now have roof up and locked, and the final thing to
do is tighten this nut again, but it doesnt tighten or loosen, just seems to
freely turn. Any one have any tips how to get it to catch and tighten, is there
a knack to it ?? Am I just being incredibly stupid, or am I missing something.
Thanks in advance,
