On a few forums members have had issues after disconnecting or replacing a battery.
Where I work we have had problems witha few brands of vehicles being sensitive to the voltage spike when leads removed or replaced.
A fix that has proven to be 100% reliable is to mount a Matson spike suppressor permanently across batt Pos to ground. (neg connection on or near battery)
also always remove Neg lead 1st.
On vehicles without these fitted we always put a set of clamps across batt Pos to neg lead to protect componentry.
On MBs the dash modules are one of the items affected.
We have tried those memory keeper modules etc but that is all they are good for IF the ign is on and cct active. This is one way modules get damaged. Key should be OUT of vehicle.
