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