Is it possible to buy a conductor plate and not have to buy the entire solenoid plate with? I'm looking for a conductor plate for my car but can not find anyone is ä, anyone have an idea how to find the right one?

What conductor plate are you talking about and what is the solenoid activating?

He's probably talking about the transmission conductor plate. How about sending it in for repair?

I thought you could only purchase new as one unit. Try a junkyard.

I have had snow inside for repair but my error code p0721, it is in module y3 / 8n4 that it has broken can apparently not be fixed

It is not possible that the article number must match the car's article number ? I have been and ordered a refurbished one from mercedes but there came the wrong item number

I had a fault code of "the internal test of Y3/8n4 has failed", and after swapping out solenoids, I replaced with a reman'd valve body/conductor plate assembly from the dealer.
The repair services listed above could not repair conductor plates with that fault code.

"reman'd valve body/conductor plate assembly from the dealer"

The conductor plate is all one piece with the "solenoid plate". they are one in the same. Dealer only. Will need programmed, will need programming and coding from the other module if you don't replace it with a new valve body.
