After a 10 days trip came back and started car, a C230K, 2005 with 41 K Miles.
Start was kind of slow.
Next day start was even slower and second time it almost did not start. Drove the car home, checked the battery, was fine 95 % but car now will not start. Key turns, everything functions but wiil not start.Will not make any noise.

I do not go to the dealer for service and it shows 730 days w/o service, or exactly two years.Could have been locked by MB?
Any suggestions?

 

would it be possible for you to visit your local autozone? they can check your charging system. however some cars they can not be tested and hooked up to their hardware.
