No 7th gear?
Hi all
Recently purchased c220 CDI AMG sport edition premium plus and don't seem to have a 7th gear.
when I manually change gear it will go M6 then D. Revs don't drop. When in manual, eco or sport the revs are still around 1700 cruising at 70.
No fault codes, judders etc. Just no 7th gear.

What am I missing?
TIA

You need to scan the TCU for fault codes with a Mercedes-specific or XENTRY.
