Hi, my 2010 ML 550 is having the brake light bulb error issues and I replaced the sockets but still same issues. I wanted to order the repair kit 164 826 0007 but I do not see anybody that has them, what is everybody doing to fix the issue without the kit or is there a recall or??

 

Anybody have any ideas?

 

Ebay. Ordered one just recently. Took very long to arrive since seller is in China. It is not MB original but the manufacturer did a decent job with it. Has original MB bag but it has been reused and resealed to make it look authentic. Doesn’t matter, still did the job.

 

most likely your problem will be rear SAM. Very common for the ageing w164. Here are some useful information for you below. I have posted recycled screenshots so don’t mind the red boxes. Tail lights are connected to rear SAM connector D (1st picture). Tail light block diagram is shown below (2nd picture) E3 for left and E4 for right.

credit to my good friend @alive19 for sharing good information as well.

here is the source for that block diagram.

 

Thank you, could you tell me what I should do with the diagrams, what I need to fix exactly and steps by chance?

 

Thank you, this is a real issue for all of us with brake light issues!

 

I cant give you advise yet since we do not know what is wrong. Anyhow, there are plenty of thread on mbworld about REAR SAM. Here is one. Worst case scenario, rear SAM is fried. Best case scenario, it is corrosion on the tail light contacts; like this thread.

Here are instructions if you are going with the repair kit in your first post.
