Trailer error codes
Recently started towing my 25' Sea Ray(7000lbs+ with trailer). Has anybody experienced false error codes in the display for their trailer? They say to check the left/right trailer lights but everything is functioning perfectly. The right turn signal indicator also flashes at a faster rate as though a light is out, again, every indicator on the truck and trailer are operating properly... Strange. I use the adapter for the 4 pin connection to the trailer. I've towed this boat with an 04' grand Cherokee 4.7 V8, 08' QX56, 09' grand Cherokee 5.7 V8 and it's shocking how easily the 550 accelerates with all this weight behind it.

I had the same problem with the ML and my camper trailer's LED lights. A Tekonsha adapter (7-pin to 7-pin in my case) fixed it.
It is interesting that my Audi Q7 never needed the adapter, and got along with the LED lights on the trailer just fine.

It's an 06' trailer with surge brakes and standard incandescent light bulbs. It throws the warnings one time in the beginning, once I cancel them they don't come back. Again, all lights on the ML and trailer are working perfectly. The strangest part is the turn signal indicator flashing rapidly....

GL550
Ok, I'm running a LED trailer and have a 2012 GL550 OEM hitch and wiring harness set up. Have never had an issue running the LED lights until the GL550. Also works on my other vehicles too without any issues. Ran fine on my GL450 and GL350 and VW. Which are supposed to have the same issue.
Installed the tow ready 20141 adapter.
New problem. The dash says trailer brake lights when turn signal or brakes applied. I thought this was the cure all, but like everything else Mercedes you have to beat it to death or get counselling.
Help!
