Turn Signal Corrosion TSB's and Warranty
Does anyone know if there is a TSB for the turn signal corrosion issues and are they covered by warranty.
Any help would be greatly appreciated.
Instead of running the turn signals off of the internal circuit board in the headlight assemblies the headlight assembly is bypassed. The main harness that connects to the headlight assembly is "tapped" into at the power wire for the turn signal bulb. This wire runs to the new modified socket and the modified socket has it's own ground wire that is run to a chassis ground.
Very easy modification to perform, provided that you have the proper tool to remove the power wire for the turn signal from the headlight harness connector. Parts are sold in a kit at the dealer. Just ask for the turn signal modification kit for a 203.
Note- this modification also applies to 215's and 230's
Thanks for the knowledge and you are correct with the fix.
I received another reply off the tech forum that gave the fix and the part number. I have pasted it below for anyone who is experiencing the same problem. Thanks again guys!
From Ausmbtech:
<There is a modified front indicator socket available for the W203 which recieves it's power dirrect from the wiring harness and earth from near the strut tower.
I was warrantable during the initial warranty but you'll have to buy it now, MB probably won't provide assistance. The parts are cheap and the installation is easy, you don't need to replace the headlamp.
Part number A203 826 0182, one required per side.>
