Mercedes S500L 1999 - Intermittent battery drain #

Posted by Paul Howd on February 20, 2012, 11:16 am

Year of Manufacture *: 1999
Engine Size and Code *: 5.0

As above,

Chassis No WDB 220 1752 A030137

Does anybody know of any TSB's refering to this? There have been seveal attempts to trace the discharge but its intermittant nature makes this basically impossible!

Otherwise I might just advise "Plan B" (Use a trickle charger when parked, and/or one of those solar panels that plug into the cigar socket)

hi paul sounds like you are having all the fun
have you tested the battery as well as a parasitic draw test you could also check the body control system for faults that may be caused by modules not shutting down.
does it have vac cdl if so they have been known to give problems as well as water ingress into front fusebox/lim unit
but the first step is to see if there is a drain on the system and how much is being drawn
