Guys - I got Max (@EleBest) to upgrade my EQS 580 to K46. It took some doing and lots of patience from Max because my MBUX was so out of date, but he got it done!

This is a FANTASTIC UPGRADE! It will drive around cars automatically. Here’s the kicker - it works with NAVIGATION TOO!

I would highly recommend this upgrade. I think your car just needs to have option K32 to get it done. Go to mb.vin to see which options your car has. Here’s the link:

ELEBEST’s K46 Upgrade

Seriously - this is freaking amazing and works extremely well!

@bdunn , I've been analyzing your post on the K46 upgrade. I'm trying to reconcile your statements with the known factory-enabled features, as your post isn't entirely clear and could be misleading for owners of different model years.

To make sure I'm understanding this, I have two quick, precise questions:

1. What Model Year is your 580? (I'm assuming a '22 or '23, based on your MBUX being "so out of date").
   
2. When you say K46 "drives around cars automatically," are you confirming this is the full vehicle-initiated "auto-pass-and-return" maneuver? (i.e., the car signals, passes, and returns to the original lane on its own, without you tapping the stalk).
   

This is an important distinction, and here is the forensic breakdown I've put together based on your post.

The Forensic Breakdown: K-Codes, Hardware & Hacking

My understanding is that your post is a fantastic find for owners of older EQS models, but it's crucial for 2024+ owners to understand why this doesn't apply to them.

Here are the unassailable facts as I've been able to verify them:

1. The "K-Code" Difference:

• K32 (Active Lane Change Assist): This is the standard "tap-to-pass" system that most of us with the Driver Assistance Package (DAP) have. It is Driver-Initiated. You tap the stalk, the car checks, the car moves. It will not move back on its own.
  
• K46 (Automatic Lane Change): This is the newer, L2+ "Auto Pilot" style system. It is Vehicle-Initiated. It decides when to pass a slower car and will automatically signal, pass, and move back to the original lane.
  

2. The "Feature-Gating" Problem:

This is the core of the issue. My research confirms that 2022/2023 models with the K32 hardware (the radars and cameras) have the physical capability for K46, but Mercedes software-locked this feature on those older VINs.

This is why a simple dealer "MBUX update" will not work. Mercedes forbids it.

The only way for a '22 or '23 owner to get the 2024-level K46 feature is to pay a third-party coder like Elebest to "jailbreak" the car's software and activate the dormant code.

3. The "K32 Prerequisite" Fallacy (What bdunn Really Means):

This is the most misleading part of the post. The statement "I think your car just needs to have option K32" is technically accurate but functionally incomplete.

• K32 is just a software code for the "tap-to-pass" feature.
  
• For K32 to exist, the car must already have the full Driver Assistance Package (P20) hardware—specifically the side-facing radar sensors in the rear bumper.
  
• The K46 "hack" also requires this exact same radar hardware.
  

So, when bdunn says you "need K32," he's using it as a "hacker's shortcut." He's really saying: "Check your build sheet for K32. If you have it, that's proof your car has the necessary side-radar hardware that the K46 hack relies on."

The Unassailable Conclusion

So, bdunn, assuming my analysis is correct, the key takeaway for the thread is:

• If you own a 2022/2023 EQS (like, presumably, you): This Elebest hack is a fantastic find. It's the only way to unlock a 2024-level feature that Mercedes intentionally firewalled from your car.
  
• If you own a 2024+ EQS (like me): This service is not needed. The K46 (Automatic Lane Change) feature is already active from the factory (or is enabled via OTA update).
  

This just clarifies the situation for everyone, as I know my 2024 580 has this functionality from the factory.

 

Correct.

ChatGPT can do a lot to work those details out. 😉

 

I am in line to make this upgrade soon!

 

Ask Chatgbt to read @EleBest Preconditions for K46 before starting to hallucinate.Pre-Condition of K46: K32 Active Lane Change Assist

Pre-Condition of K32: P20 Driving Assist Package Plus (Country Dependent)

 

Hey, you in DFW area too? Would love to hear how the auto lane change works in TX? I'm thinking about it but seems like a lot of work.

 

I am in DFW. So far the auto lane change works great. It was actually very little work. Max handled it all via Internet. I did have to get my MBUX system up to date but that needed to happen anyway. It’s pretty simple to get MB to do that for you at no charge.

 

@bdunn , let's start with your comment:

"ChatGPT can do a lot to work those details out. 😉"
You're right. But so can knowing the subject very well from a combo of actual hands-on experience and research.

As for who is doing the work? It's not AI, it's just JB. 😉

Your post was "low-effort" and vague. It left out all the critical context: What model year? What does "works with navigation" actually mean?

These are "amazingly complex," ever-evolving machines. MBUX is not simple. My post was thorough because this topic demands thoroughness. My intent wasn't to be "negative"; it was to "fill in the gaps" you left, to provide the "added value" and irrefutable context so others can have confidence in the information.

Not everyone has the time or patience to provide that. I do, and I enjoy it.

That's not "AI." That's called passion and intellectual rigor. And if you think, for a single second, that AI can synthesize a specific background in business, law, and psychology with actual hands-on experience... well, then you are sorely mistaken about how this technology works.

You've certainly expressed appreciation for my level of thoroughness in the past, so don't take it personally that my precision is offending you now.

And as for @trigital who "corrected" me with this:

"Ask Chatgbt to read @EleBest Preconditions... before starting to hallucinate... Pre-Condition of K46: K32 Pre-Condition of K32: P20"


I'd suggest you take your own advice.

Before you start to "hallucinate" a correction, you should have actually read my post.

If you had, you would have saved yourself the public embarrassment. But I'm glad you didn't, because you've just provided a perfect, case-study example of the "low-effort" archetype I was just describing.

In your blind haste to land an insult, you did two things:

1. You 100% confirmed that my "forensic breakdown" of the K32 and P20 prerequisites was completely and irrefutably accurate.
   
2. You 100% proved that ugly, diminutive, low-effort mythical creatures don't just live under bridges; they've learned how to use a keyboard.
   

Thank you both for the confirmation.

 

AI doesn't have the unique rhetoric posses by J_Boxer . . . at least I have not discovered one. You can ask AI the right questions, and it will give you the answers and piece it together for you all day long. JBoxer can also do the same and entertain you at the same time. JBoxer is years ahead of the current AI state.

As for the coding, if it hacks the MBUX, I guess a new update to the MBUX by the dealership will erase the custom coding, right? Beside, when I switch lane, I don't need to signal if no one is behind me. It is more needless effort, inefficient, and puts more wear and tear on the stalk. As with all nannies, drives like a granny. For me, this assist stuff should be all or none. Level 4 or 5, or no levels. Anywhere in between is like watching someone drive your car not the way you want it. . . . interesting at first, frustrating on the long run.

On a slightly different note, a plastic grocery bag flew across the front of my car, and it engaged in a quick emergency braking. Unbelievable . . .

 

Sorry if I offended in any way, "hallucinate" was about Chatgbt not about your essay, which is great.
hallucination, besides thinking and reasoning is one of the AI parameters.

Is nothing wrong ( in AI perspective) to hallucinates. This way the AI model do his training ( learning large models from you as primary scope).

Coding is far more primitive, especially on Mercedes.

As Coding or enable a function is not a hack and this doesn't have to crack the original code, the functions will never work if the perquisites is not present.


So all arguments exposed in your study/essay is not available in the real world as for this case is more like "common sense" or the normal state of things.

 

K46 Done ☑️

 

Best coder ever!

 

I want to do it too!

Ok, so i had EleBast to install K46 in my 202 EQS 580 and after testing it i have to say i am really impressed and VERY, VERY pleased with it!!
It not only automatically changes lane to overtake and goes back to the previous lane, but it also automatically puts you in the correct (slower) lane if there is no traffic around.
So far i have to say i love it and that it's worth every cent paid.

 

K46 Upgrade

Thank you @TR-EQS for the feedback.

Really nice upgrade for 2022-2023 EQS with K32. Cheers!

Thanks.

 

so it follows navi to get you on and off highway as well?

my car doesn't even pull me back on lane...

 

I have only tested it in one trip, but no i don't think it drives like the Tesla navigate on autopilot.

Mine puts me back on the previous lane, though, and when there is no traffic at all takes me to the slower lane.

 

I have it on my car, which I’ve had for a year now. If you’re on the highway and are running navigation and cruise control and are approaching an exit it will also automatically move you into the correct lane for the exit. If you turn on your signal, the car will also automatically safely slow down to take the exit (though I think that part is independent of the automatic lane change, but the two work well together).

 

Hmmm... interesting.
I will definitely try it with navigation and cruise control running next time.

This was my car last night. We are about to drive on a 1500 mile trip each way and recently MB dealer did a full reset of everything on the car as well as replaced the windshield. Wiped out everything. Max recoded K46 and even coded something for me I wasn’t expecting that will greatly improve our upcoming trip. Everything works like a charm. It’s still amazing.

@EleBest is simply the VERY BEST! If you’re in the Mercedes world and need reliable, expert remote coding without the dealer hassle or markup, @EleBest is the guy. I cannot recommend him highly enough. Top-tier service, perfect results, fast turnaround, and real results.

 

I do that anyway and drive slow so maybe it would work for me
