Can someone please confirm if the 2009 model has a fuse for the taillight parking light? I replaced the Taillight Bulb Holder with Bulbs ( incredible they don't sell just the light bulb) turn signal/brake light/reverse all are working.

More than likely you will need to replace lamp support.

Regrettably there is no fuse in your system. Either the socket you purchased is faulty or there is a issue with the rear SAM that provides the final on off request------however, what about the other side----------- do all the bulbs function???

Thank you, now I know there's not in use so Ill continue with the next thing, I ordered the Mercedes Tail Light Bulb Carrier , installed and nothing, thinking that it was defective I returned and received another one and again nothing, both of them OEM brand new.

The right side everything is in order, we then ran a scan and nothing is coming up. Photos attached

Again only the top right bulb is the one not coming on.

Wiring...

thanks, I will try to switch the left to the right to see if they light up, if that doesn't work finding the bad wire is going to be a challenge.
