When you say 'a 13mm bolt' do you meah spanner size or thread diameter. Also a pic of the bolt may help with identification

Some pictures!
Its the bolts head that needs a 13 mm key. On the picture of the engine bay, you see the bolt laying on some black gear mountings. Actually, I found it 2 cm further back in between the gray chassis and the black gear mountings.
Good luck with the identification! Your help is much appreciated! I cant figure out where it belongs.
Cheers,
-P-
Have you found any others with the red paint on ???

It could be that at some point some work had been done they dropped a bolt, unable to find it so fitted another then this has just appeared from wherever it fell
