Hello. I recently replaced the front headlight assembly on my 2000 S430 with new style (03-06) headlight assembly. After the mechanic installed them, the headlightsappeared to work fine for about 10 minutes and on my drive back, I got two errors one was the left low beam light error and the second one was the right fog lamp error. Anyways, few days later I took it back to the mechanic who employed some di-electric conduction fluid to the connectors and everything started working except for the right fog light. What could be causing the right fog lamp to not work? Initially when we installed the new assembly, everything was checked to make sure the head lights were working properly so what would cause the right fog lamp to start misbehaving? Please advise. And again, thank you for your help, in advance.

 

the resistance is measured by the lamp control module everytime you operate such accessories.

compare the resistance with the left one.

make sure the ground is properly fixed.
