Looks like it left the factory like that!

I really wanted this glk just not in the cards for me right now.

Saw the GLK up for auction and wanted to come here and thank you for all the work you've done and shared. It's been inspiring to see someone else out here doing this stuff and helpful when I ran into a few issues. 

I have the M156/6-speed 500E and have also done 2 CLK63 Black Series manual swaps so far and many more scheduled. I sent the ECUs to Josh at MSS to add the resistors but I'll probably do future ones myself. The 500E doesn't have a clutch switch, he just did something with the tune to make it not care. Hyatt is right, I do this for a living and don't post much about how I make it work, but I try not to be too gate-keepery when people ask how.

But of course I also have a question. Did you ever run into any ESP trouble? The CLKBSs give me an "ESP Inoperative" message when first started which goes away, no lights or anything, and then acts normal. But when I go into the ESP in SDS it doesn't give me any coding options or even tell me whats wrong apart from a code for an ECU mismatch.

Never had a problem with ESP. I coded my ABS module from automatic to manual and that was the only change I needed to make there. You should get away from DAS/Xentry for coding and use Vediamo, it's much more powerful. 

It's funny MSS is working on the ECU for you. When I reached out he told me he'd done dozens of swaps and you just plug in the clutch switch input and it just works. Nice to see he's benefiting off of work that I figured out now.

So when it comes down to it I really don't know that much about the software side of things. Generally enough to accomplish what I need in DAS but I really need to learn more. Most of my time is spent on the hardware side of things for putting M113s in W108s and stuff like that. Is Vediamo just software, or is there a hardware component as well? Will it work with my C3 multiplexer?

He's been picking up a lot of tricks in short order as I and undoubtedly many others are prodding him to do more with these ECUs. At first he just told me to plug in pin 26 and that didn't do anything. No doubt he learned about the modifications here. When you reached out we'd only really done ME2.8s, the 500E was the first ME9.7 build. I'd love to do everything myself but when it comes down to it I just don't have the time for everything. What year ME9.7 are you using? The early ones seem way simpler than the later ones inside.

Yeah you can use your C3 with Vediamo. Vediamo is MB engineering software, you can do variant coding and module flashing with it.

I'm using a 2010 E550 ME9.7. They should all be the same though V8 to V8 and V6 to V6.

Its easy to catch onto if you have the mind for it. But learning isnt hard either. I'm sure you can figure it out, Matt.

Does anyone know if the manual transmission on W204 is the same on engine OM651 and engine OM646. I want to swap 651 with 646 but I'm not sure what I will need, except engine and ECU, of course. I will be glad if someone share their experience and knowledge. 

Thanks you

I doubt they're the same. This would probably be a better question for a European central forum though since we didn't get anything diesel/manual here in the states.

In every forum I asked, all of the people say it will be too expensive and it doesn't make sense. I have searched for numbers of the transmissions but I don't have success. This is the only post where I found that someone have changed from automatic to manual, because of that, I asked. Do you know any other forums where I can ask?

I would ask on an UK based Mercedes forum like mbclub.co.uk or the Sprinter forums. The typical Mercedes forums are very much useless when it comes to this stuff.

The OM651/646 are inline 4 engines. As far as I know the w204 only had manual transmissions for the V6 engines here in the United States. Its mostly safe to say that Mercedes bell patterns fit each other in this way: Inline 4/5/6 engines share the same bellhousing pattern. V 6/8/12 engines share the same bellhousing pattern. But you cannot take a transmission from a V engine and bolt it to an inline engine and vice versa.

So, I say all that to say this, unless you can find a inline 4 w204 with a manual transmission then no the OM651/646 cannot use w204 manual transmissions. My caveat is, outside of the United States, the w204 came with inline 4 diesels that had manual transmissions, those manual transmissions will work on both the OM651 and OM646. Sprinter vans that shared the same drivetrain can be included in that caveat. I believe the transmission part numbers should start with 716 and 711, for example the 716.754 and 711.680 transmissions.

I'm 95% sure in the accuracy of this information.

I hope this helps.

Thanks for the information. Here in Europe we have 4 cylinder inline with manual transmission. I have already ask in Facebook group and hope to have there some more information. Because of the lack ot information for swapping engines, I decided to buy whole car for donor. Because I don't know, if the installation and the ECU can communicate with my car installation. I hope you understand what I want to say, because my English isn't the best.

I think I misread your original post, are you swapping from an OM651 to a OM646 and you want to keep your manual transmission? Or something like that?

Yes, that's right. I want to swap OM651 with OM646, and to keep my manual transmission. But I don't know, if my installation is compatible with the ECU from OM646
