Current status says this (picture below) and I do not know how to proceed.

Well it says do initial start in gateway module. So do it.

at

 

[W221 S350 BlueTec Ed]

Any other option?

 

[Deplore]

Ah, you need online account to scn the CGW. Recommend finding a Indy nearby, or go to dealer and have them code it.

 

[Deplore]

In regards to your pm, an Indy is shorthand for independent, meaning a mechanic shop that's independent from the dealer.

Any old Indy won't be able to do it, you need to find one that specializes in Mercedes, they likely have the equipment or the account to be able to do it. Often are cheaper than dealer.

Or go to dealer.

Thanks for the info, I will post any updates on the issue. 1 more question for now I bought this machine do you know how I can get an online account for myself? Or is it not worth the effort?

 

[Deplore]

Online account costs $6000 a year... It also comes with SDS when you buy it from Mercedes.... Only costs $38k!

Will a tuned ecu solve my problem? If I have to pay the money I may as well be something out of it right? Please let me know if I am wrong.

 

[Deplore]

Tuned ECU for what? We're talking about CGW here, it's a router for all modules in the car to communicate with each other.

This is a separate module, has no bearing on ECU.

Ok thank you

Can you enter Control Units/Body/CGW and get past the message you posted above?

Oh and I screwed my car up with this

Can you elaborate on this statement? It sounds like the Central Gateway lost its coding and now the vehicle is unaware of the options that Daimler installed from the factory, or any options for that matter.

If you do not have a Xentry Flash account, Xentry/DAS is good for performing diagnostics only (unless you are a very experienced user that can read German and have an illegally hacked version of Xentry from China.)

Kudos to you for being brave enough to try. It looks like your diagnostic is quite robust. Can be very useful... As much as I would like to try and use a tool like this I don’t think I would unless I had someone that could walk me through everything. It’s also expensive... I have limits.

Ouch... $2,200... was that mostly labor? Were any parts replaced?

 

[W221 S350 BlueTec Ed]

They said I fried my CGW but I have a hard time believing that I should of asked for old parts but whetever they fixed it. Now it’s puzzling though nothing was wrong with the car on the way home how does it all of the sudden not turn over or even click like it’s a dead battery
