Hey guys. My first post on this forum, just wanted to say hello to all you good people.

I have a problem with my 2006 CLS500.
Yesterday i got to work, shut my vehicle off and light off, I get out of the car and I see my tail light (bottom part right light) won't turn off. I went back in, started it up, got message on dash: "Display Malfunction: contact service" or something like that. Turned my light on and off and the part was still on. I ended up pulling the carpet off and unplugging the right tail light to keep it off so my battery wouldn't die. Well sometime at night I noticed my left bottom tail light was flickering and blinking every now and then. When I got out of work in the morning, I went to use the fob to unlock the car but fob was not working. When I click the buttons, the little red light on the fob light up but no reaction from the car. Good thing I left it unlocked. I then tried to open the trunk with the button from the inside, using the fob, and also just by pulling the handle up physically and it wouldn't open. I had to take the physical key out of the fob, insert it in the key hole, and pull the latch to open the trunk. Any ideas what the heck is going on? Please let me know.

Ps also notified blinkers now working

below is the link to the video I uploaded to YouTube so you can see what it does:

Any ideas?

Are you able to scan it?

The first thing I was thinking is water ingress somewhere which throws off the electrics.

Yeah my buddy was able to scan it, it had bunch of codes. I'll have him check again, I forgot what they were for,I'll get back to you

Here are the codes

Wires breaking that are attached to the left boot lid hinge are a problem. A loom is taped to the moving hinge.

I will look into it. I thought it would be the SAM module in the trunk , maybe had moisture?

Could be alot of things, make a list of possibilities and go through it or find someone with a flash scanner. If it was wet when it hsppened and that was the cause it should change once dried out. I found 6 of the hinge wires have been repaired on my 350 that Ive only had 3 days just checking continuity and earths. Wet weather also lowers voltage from lights, wipers, demister, heater etc.

Wires braking is very common, old age and it being wrapped to tight is a no-go. I think almost all cables in that loom have been repaired in my CLS55

So we replaced the sam module and everything seems to be back on, got rear light on, trunk opens, alarm works, blinkers, Windows roll down, defrosters and all..we found corrosion and moisture inside he sam

The corrosion on pcb boards conducts when its wet and doesnt when its dry think I'll check mine as boot functions not working properly and third light has been messed with showing a message on dash. Glad you fixed it.
