I check the fuse the connector the bulb and the wire all ok

dont know what ai need to do now any ideal to help me

 

Why did you change the rear SAM?

Where did you get it?

Was it the same part number as your old one?

 

The rear Sam have corrosion try to fix it and a lot off think don’t work it’s better now

the part number was check by Mercedes they give me the new part number and I bought it from eBay the place is California it’s a Oem

dealer make the re programming and said it s fine and don’t understand why I do have code

 

Well, what are the code numbers?

 

No code number with obo but the code when I start the engine is

rear trailer brake right and left
rear trailer flasher right and left
right flasher but have bulbe and work great but run faster then normal

some code like this I have

 

Do you own your own scanner, NOT A CHEAP CODE READER?

 

The code I have it’s when I start it in the front off my dash

no scan reader expensive I owne a cheap one

 

Post a photo of the dash.

You must have a scanner of your own or every thing is guesswork.

 

 

You don’t see anything pic is no good

but it’s said trailer light right and left and flasher and brake left and left

no fuel

 

Francois, because of the language barrier I cannot help you any further.

 

tank you have a great day
