Professional Tuning ..Emulators .. Deletes ..STAGE 1? Ncv3 2010+

Hi Guys,

I have a NCV3 2011 sprinter with 200k miles and I had a check engine for def heater(I had it for over 2 year and finally got to fixing it ) so I replaced it with a brand new factory oem unit codes cleared but soon afterwords i was awarded with a limited starts message . Coincidently it came at the time when I needed the van and I needed to get a rental truck to not risk the countdown to go to 0.:thinking:

Not wanting anything like that to ever happen again I did a little research and saw people had good results with def and dpf deletes so I sent my ecu to get tuned for dpf , Def, no starts , etc.

It came back and the van would shut off completely randomly when testing it less than 1/4 mile. The tuner would not reply back to me so i found another tuner claiming is the best of the best and of a select few that has subscription, passwords, and access to the mercedes database.

So I sent to the second guy now in hopes of just getting bad luck the first time around and second guy sends it back. I put it in but the car feels very weak as the turbo is barely engaging and I'm showing high load(80-90%) when driving normally on flat land but atleast its not shutting off randomly .I would love to diagnose the problem and say it was my fault somehow in the turbo install. All looks visually well but the mercedes das system does not recognize/ cant connect to the ecu and I cant perform any tests or see any faults. Only with a generic obd2 i can see faults which gives me some bogus codes at the moment .

I expressed my concerns and the tuner had told me that my car he thinks my car has a lot more problems than I think and to get them fixed .
I am pretty hands on and know my car very well pretty much do all maintainance and minor repairs my self . The only problem I had was a def heater code p202a, but the car did sit for a few months as this was all getting done (yes few months) and I did replace the turbo and actuator so i had to give him the benefit of the doubt.

I went to 4 mechanics including two that I personally know to get opinions and all 4 thought that its a ECU related problem. . The c3 my friend had was unable to perform simple tests of any kind (i was hoping to test the turbo actuator) and it was showing the voltage on ecu as 15.1 but the car voltage is 14.1 via crawled to the alternator and confirmed indeed the voltage is 14.1


So I just tell the 2nd tuner to put the factory software on the ecu.

Fast forward the 2nd tuner said he put the factory software back and I installed it in the car today and key turns says 9 starts left on screen but no click, no crank and no start attempt whatsoever :bash:


Now this section is dedicated for the sprinter emissions police with the white sprinters commenting there 2 about deletes, boring threads to the point of extinction with words that i truly don't give a damn about. I beg you, go comment elsewhere and leave this thread alive :rad:


I'm all out of ideas. I beg :bow:the Spritersource community for your thoughts and help.

There's a lot in there, you casually mention "turbo install" along with everything else. Want to tell us about that? Why was it done?

From a cautious/scientific standpoint, you want to slow down, think, and minimize variables. What else did you change?
How many things can you change back to when it was running? You may have to go backwards before you can go forwards.
Check all the basics, fuel, compression, in our case not exactly ignition, but glow plugs,
Then change one thing at a time.

If your handle refers to California, not Columbia, how are you planning to pass emissions testing? :tongue:

There's a big long thread up here somewhere about "no click, no start" or something like that, read all that, it's probably got your problem in there twice at least.

This is a similar thread: https://sprinter-source.com/forum/showthread.php?t=62815&highlight=click+start
Check it out, particularly post 14

Good luck! :thumbup:

You want some advise !
OK first YOU ARE CRAZY!
To entrust people who have little or no experience working on your van.
From your narrative you clearly have guessers, theorists, or star gazing, beard scratching diagnosticians at work on your behalf.
How many of them work on Sprinters on a daily basis to be able to adequately diagnose drive ability issues.
How many of them have actually had formal auto tech training in a tech college dealing with diagnostics . Are they YouTube graduates? If so run way !
Would you allow an untrained dentist to extract an aching tooth?
Ask yourself that!

Fixing Sprinters and many other modern day complicated vehicles requires training and individuals with critical thinking skills combined with circuit analysis abilities to run down drive-ability problems. MB products are some of the worst for this followed by BMW.
Now without any modicum of apparent training, other than thinking you are good at fixing cars you have come up against brick wall.

Do you have any idea of how many even trained techs I wont hire because they cannot fix MB & BMW products quickly efficiently to make my business a profit without expensive comebacks ?

Now you have done research, it begs the question how much research ?
If you had called me I would answer that few of these so called tuners do a good job.
In fact earlier this year, we would see about 4 four units per month roll in with similar issues such as yours.
In the main the biggest issue I see/saw, is that most tuners dick with the EGR valve and the EKAS system and then have to reduce the turbo operation to reduce the likelihood of turbo over boost & auto shut down taking place while you are driving.

So where do you go from here?
Clearly you now have a van as a lawn ornament, since it seems like its been VOR for sometime now.
So some advise!
Remove the ECM and sent it to SOS Diagnostics for an over check.

After all this dicking about you MIGHT need a new ECM at about $900 re-conditioned.
Once its back, find a shop or someone who can do a total print out of live data values in both KOEO and KOER to establish what is ACTUALLY WRONG with the van.

The actual fix might be a lot cheaper than you have spent so far cutting off your nose to spite your face--seriously.
By the way in these circumstances an MB dealer might be your friend because that C3 clone scan tool won't do updates and re-flashes which is essential with the ever changing exhaust system after -treatment software/programming that has been developed over the years to improve reliability.
I receive updates about three times a week on all MB models due to updates & re-flashes.

Please understand that the DIY'r is slowly becoming an enemy of his own vehicles, due to these factory controlled software update issues that can only be obtained by subscription and adequate tooling & investment. SOS will update the ECM to the latest & greatest.

Post the live data values and I/We might be able to suggest something constructive other than cutting bits out of the programming.
All the best
Dennis
