SLK 55 Can Bus issues

[Punchdrunked]

Good afternoon from the UK

Attached is a Xentry read out of a number of issues that I’m grappling with on my SLK. Other codes not pictures include H3/1 alarm siren inoperative and head light range control issue, although this is probably linked to the replaced LED headlights that I’ve fitted.

I’m trying to resolve this and hope sobeihe knowledgeable can chime in with some advice, guidance or help!

Thanks
