W211 problems
I recently overhauled my engine and gearbox about 2 years ago and have not been driving my car for about 2 years because I was out of country. Battery drained out and asked a friend to install new battery and he installed it wrongly where positive into negative and negative into positive for few hours and installed it correctly again.
issues I'm facing
1- key unlock and alarm does not work
2- gear transmission is stuck on maybe 2nd gear and I cannot use the manual method to shift my gears as well
Appreciate any trick or hack I can do to sort my problem.
I have tried the TCU reset but still it's the same
please help

clear codes, erase them while stationary engine and see if they come back.
