Hello all, I am having a problem with my 1985 500 SEL gray market, the cruise amp went bad so i ordered a new one from mercedes and it has a coding reley in the bottom of the unit, ok so it will not work at all, wont set or accelerate it is just as if it is not pluged in under the dash, i have another amp that has a problem with keeping up speed and it will work in the car so i dont think i have any trouble in the car, i even ordered a second amp from mercedes and it wont work either. My question is is there a difference in the amps or do i need to change some wiring in my car to make the new amp work??

I hope someone can help me figure out this problem..

Thanks

Rob...

I have a 1986 300E, I wonder if it uses the same CC amplifier than your car. Mine works intermittently. I opened it and resoldered all joints, that made it work for 3 days straight. Since then it has been disfunctional for about 3 months. Before that it did not work for a year. If one of your amps works in my car I would seriously consider buying.

I bought a amp and Actuator from them over a year ago for a Euro 16v and have had no problems.
