tcm code with a manual transmission?

A great question; the "EGS electronic transmission control" is listed as a probable cause, but I am with you - not sure how there is anything for the transmission in a manual. You may want to reach out to a specialist near you who works with German vehicles - check this link to find someone close. https://repairpal.com/auto-repair-near-me I find that low battery voltage often generates goofy codes, so make sure before all else your battery is fully charged and able to take a load, then clear the code.
