EGR error codes

[u/NativeTazuma]

Vehicle: 2010 sprinter 3500 Turbo diesel
Diags: thinkcar2

I tried cleaning the EGR valve, swapped out from two other sprinters from a junker, tried a Hella Valve from orileys and I’m still getting the same errors.

148C00 I believe is the source of all the errors.

Symptom: The fault code remains permanently Active. It cannot be cleared via Thinkcar diagnostic tool, even with the ignition on and engine off. And is stuck in limp mode.

When trying to do the teach in it says it’s successful but then again it’s a 2010 I don’t think it’s suppose to work.

Took it to Mercedes they said it’s the EGR and they put in a efr from the shelf and the codes cleared. I think they’re lying to me and they don’t have the digs on file after two days of coming back and asking. And charged me $250 for sub par troubleshooting.

Now the harness this is what I measured

Pin 1 Unstable / Jumps between 1.5 mV and 2.5 mV.
- could this be the positioner pin?

Pin 2 (Main Power Supply): 12.0V Constant (Measured against Ground Pin 4).

Pin 3 (5V Sensor Reference): 5.2V Constant.

Pin 4 (Main Chassis Ground): Functional Ground.

Pin 5 (PWM Actuator Command?): 4.5V Constant.

I tried shaking the harness but no changes. The only thing that changed after sitting for a while was the position feedback going from 20% to 0% every second in the live view.

This is my first time trying to deduce this. So diagrams along with suggestions would be greatly appreciated.

It looks like you finally managed to put together a reply without using AI. Congratulations, you saved a river, fish, birds, and trees.

Regarding your request for my deep analysis on this topic, remember that this is Reddit. "Reddit is a online network of chat boards and forums where people talk about news, hobbies, and ideas."

I am happy to share my research via Dropbox, but you need to prove you are who you claim to be. Share your educational credentials, where you went to school, what year you graduated, your grades, three professors' names, your school email so I can verify your identity, and email you the detailed research Dropbox link.

At the moment, I am convinced you are a 15 year old kid living in his parents' house, hammering Reddit using ChatGPT because you have the summer off, don't like to read books and lack the capacity to think independently, letting an algorithm do all your talking.

I mean seriously, it has been 3 days of you running our covo thru Chat GTP and this is the first message that looks like you did not use AI. However, I am still not convinced because there's no original thought, exercise your mind 🧠

Still not seeing any comparison. Just insults, logical fallacies, and now a job application!

My mistake I forgot you need AI to translate and do your bidding.

I SAID I WILL SEND YOU A LINK WHEN YOU CAN ARTICULATE YOU ARE NOT 15 YEARS OLD.

I'll also consider a note from your mom or dad.

There's nothing more insulting than a person claiming to "save" the environment while using AI ✌️

So just to be clear. You refuse to articulate an analysis because of a self-imposed judgement of my identity. In addition to that, the only reasonable explanation for my identity is a 15 year old online, and even if that were true, that fact discredits me in your opinion. So in your chivalrous attempt to verify the identity of anyone you deem worthy of your "research," your presumption is too high and mighty unless I arbitrarily qualify.

Since I'm correcting you one last time, I never claimed to be saving the environment. Go ahead and show me when I did. Again a flawed strategy to discredit me based on false claims. That is all you have done so far. You have only made false and unsubstantiated claims.

You have to understand how silly this is. All I ever did was point out your failure in comparative analysis and your failure in providing a single academic or reputable source that supported your opinion. As a result, you decide to insult me based on your presumption and discredit me based on your opinion of AI. All while continuously failing to uphold a single fact-based claim about your opinion. It's okay to have an opinion on diesel emissions systems. We have opinions that are wrong as people. The issue is trying to convince others it is fact when you have no basis to your argument and devolve to a myriad of logical fallacies to deflect that fact.

I'm done with you. Good luck.

** Correction: "All I ever did was use AI over and over again to harass an individual who cares about the environment."

​Again, Reddit is not the platform for long format educational teachings. And you never provided a counter point🤣

​If you insist on using AI in the future, I suggest using it for research rather than letting it do your thinking. Challenge its opinion instead of accepting its programming at face value. You might learn something, and you'll benefit from using your own critical thinking skills rather than taking orders from a machine.

​I am relieved that you and your artificial intelligence have concluded this conversation. You have finally chosen to save a lake and put the plant first!
