Change batt

change batt. now my check egn.lite is on, ABS lite is on, speed odo.doesn’t work,

what do I need to do

Uh oh! What year is your Benz?



I think that anyone who owns a 2000 model year vehicle or newer should read this before disconnecting the battery.


So if I go and erase the codes will this take careof the problems

No. you want to drive the vehicle for a while and see if the computers/modules will relearn their adaptive memory. If after a hundred miles of driving, and there’s still a problem with any of the systems, it means a trip to the dealer.
