Hello y’all, just replaced my conductor plate in my 13 c250 and everything seems to be working fine, but the car will not go into reverse. When put in Reverse, the car acts as it’s in neutral and revvs and just rolls forwards. I had the conductor plate programmed to my car so I thought everything would work as it should.
Anyone got any tips?

1. Who programmed the car? Take it back or have them come pick up you car and fix it. Or...
2. Cancel payment to whoever programmed the car and contact @BenzNinja .
(By the way, notice how I deleted your pics when quoting you? That's what you are supposed to do so people don't have to scroll through what they already saw.)

I’ll remember that! And it was a guy on eBay all the way in NY (I’m in AZ) who did the programming.. I had to send my old plate with the new to which he Aparently connected the vin and the adaptions from the old plate.. I reached out to him and he said that the car needed a learning adaptation with the range selector.. fast forward I bought the function on my launch obd reader and did the steps and yet it still will not shift. Although.. during the shift relearn drive does become available but the second you take it out of Drive and put it back it becomes inoperable.. cars been a real money pit for me recently so hopefully this can be fixed soon..
thanks!

first of all
There is no Launch, no Autel, no aftermarket tool that succeeds 100% on MB
not that this absolutely the cause, might also be the programmer that messed up
Only real diagnostics will tell

As good as Launch, Autel, etc. are good for a lot of things, when it comes to stuff like this, you need to go with XENTRY. I had iCarsoft mess up my radar for Distronic and Pre-SAFE braking (actually, I mess up using iCarsoft) and had to use XENTRY to restore the radar function using the Teach-in process. So, I have learned to use aftermarket scanners for reading and clearing codes and other simple stuff, and use XENTRY for the important stuff.

You have a LAUNCH scanner with the Mercedes program. Not sure if you borrowed that or own it. If you own it, then you are a DIYer. Not sure how long you have owned your car or why you replaced the conductor plate, but if you are going to keep your car, you really need to get a XENTRY/DAS setup with a C4 multiplexer and get a membership with @BenzNinja or end up going to the Mercedes dealer every time you come upon a problem like this. XENTRY/DAS (DAS being for older cars) is more than a scan tool; it is used for configuration, adaptation, actuation, guided trouble-shooting, guided start-up procedures, etc. specific to your car. Even the best aftermarket scanners don't do all of that.
Looking at the tranny relearning procedures in XENTRY, there are several different procedures provided. One procedure REQUIRES two people to perform: one drives at specific speed, etc., while the other monitors and initiates the progressive stages. I'm not sure if this is required for your car, but it may be.
I replaced the conductor plate on my 2004 SL500 myself after getting it repaired. The service I used (www.CircuitBoardMedics.com) did not require any re-learning, even when they had to use a substitute (used) conductor plate because I broke off the multi-pin connector removing it from the transmission (a sickening sound of plastic cracking). However, later I finally went to the dealer and had them replace the conductor plate with a new one. I think the cost was around $1500 total -- not bad.
My point being is that with Mercedes, they are generally easy to work on, but they do have their quirks that require professional service. It doesn't always have to be a dealer, but it does require someone who knows what they are doing.

Good luck!
just yesterday I had my car at the my local Mercedes dealership (not really local it was an hour away lol) for a battery problem (was under warranty) when it was there, I had them diagnose the car for the car not shifting and they said 1, found the used conductor plate which they said was not the smart way of doing it, and second, that the cars lack of shifting was due to incompatibility with the conductor plate.. 400 diagnostic charge later and they quoted me a new conductor plate and instillation at around 2300 and some change.. let me put it in perspective, the mileage the car has (163,000 miles) and with that said, it would be stupid of me to even consider having the dealer fix it.. at this point my goal is to get the car driving just to sell it because as is not movable I’ll get less then what I’ve paid for the new parts in it as it sits.. so with that said, I need to break out the ol piggy bank and spend a few nickels lol.. I thank yall for the help and I’ll update when there’s one to give!
thanks yall!

Unfortunately, I think your dealer is right with regards to using a used conductor plate. When I had to finally go to the dealer for a new plate, it was around $1500 installed (or maybe $1800). That was a few years ago before this current administration sent inflation soaring with its stupid energy policies (but that's a discussion for some place else). So, depending on where you live, $2300 may be reasonable, I don't know. It would be nice if they credited the diagnostic fee.
