If you need the latest sat nav disc, check the bay where pirates are found
;)

Great write up. On my US Model w211, everything is located on opposite side
.
I just bought a 320cdi with same problem…was thinking it was bad
alternator…but now i know…Great Video and will save a lot of
worry…Well Done…have to find sat nav cd now..
on the SL the boot battery runs everything and SBC the engine battery is
for starting. is the Eclass different?
I usually just take the battery to an auto parts store, like auto zone
here. They have the big ass chargers that fully charge and test within an
hour.
Disconnecting of main battery is it not problem for Computers and control
system?
Do you really need to charge a new battery with fresh electrolyte? I
thought the whole chemistry thing took care of that?
Charging the battery won’t fix the problem permanently, you need to figure
out why it went flat. The wiring from the battery control module to the
auxiliary battery charge relay is the most common cause. It usually breaks
in the engine compartment underneath the washer bottle filler neck, on
right hand drive cars at least…
Lead acids can take an age to charge and fast charging them is really
really bad for them. You can’t just crank up the amps, you will ruin a
battery trying that. I half expected thefault sign to come up again. Some
car makers make it so the fault codes need clearing mine did after a minor
fault I fixed. I ended up buing a code reader for my pc so I could read and
erase fault codes. Makes finding some faults easier too!
