I'm new here and firstly apologise that my first post is a question...I have never owned a MB before ..but in 6 months have been lucky enough to buy 2 ....one runs fantastic and the other one has got me against the wall.....thats the one I want to talk about its a 2003 W211 E200K with a lot of electrical problems,
The tail lights are all over the place ....no tail light on LHS, dim on the RHS, no reverse lights at all, one dim number plate light.
When I put the indicators on, one of the license plate lights start flashing and one of the interior trunk lights too....as well as the right hand tail light.
Indicators sort of work but not fully...only one of the 2 indicator lamps light up. Have checked both lamp units all OK when I check the bulbs individually.
The reverse lamps do not come on at all.
When the lights are switched on...one of the RHS tail light comes on very dim..the voltage is 4.3V...the LHS is completely dead.
If I disconnect the LHS taillight completely...the interior LHS trunk light goes dim.
If I open the trunk the LHS number plate light..which is already dim goes off...and comes back on again once the the trunk is closed.
The brake lights work fine....so am only driving it during the day !
The trunk switch does not work with switch or remote....tried looking for a bad earth in the trunk area...no go...cleaned all existing ones.
And to top it all off...the rear head rests don't go down when I press the button on the centre console.
I have had it star diagnosed...came up with a lot of errors...all cleared out..I have the print out.. (probably due to the battery completely dying and foolishly connecting the battery the wrong way).
Going through the posts on this forum and others they seem to be pointing to the Rear Sam ... although looking at it you could swear its an earthing problem (have cleaned and checked earthing point in the LHS of the boot area near the sam unit and also the battery earth from the earth wire to the box voltage doobery to the body).
...any help or suggestion would be appreciated.
