Mercedes Sprinter 313 CDI 95 kW 2012 Check Engine flashing after DPF EGR OFF

[Codelove]

Mercedes Sprinter 313 CDI 95 kW 2012. I removed DPF and EGR with ADS DPF/EGR Remover and fixed checksum with WinOLS. The vehicle is working, but its Check Engine now flashes. Earlier, it was simply there, but it wasn't flashing. I found a similar thread on another forum (https://mhhauto.com/Thread-Mercedes-Sprinter-W906-313-CDI-95KW-problem-with-DPF-off-CDR2-ECU?page=3) and the people there asked for the ECU. I uploaded the original ECU (HW_6519020100_SW_6519025100_READ), which was read by KESS v2 clone from AliExpress and the DPF/EGR OFF file (WinOLS DPF_EGR_OFF).

What's the problem?

VIN: WDB9061352N511087

Edit:
I scanned with Delphi and the actual model was actually W906. I deleted the fault codes for the DPF and they seem to be gone, but the Mass Air Flow is giving Invalid Signal. Is it possible that the MAF is the reason? Thats the only error code

not got solution

Elaborate.

It seems like it actually worked. I just removed all fault codes using Delphi and the check engine is probably caused by the MAF as it is the only fault code right now. We will see when it's replaced in 2 days.

I had similar problem , you can turn dpf off with star diag . After correct solution your lamp will blink , Look at injector codes. my problem was ECU , I OPENED IT and found one pin burned.
Solution when lamp is blinking is remove battery or 3 times put ignition on and off . If still blinking with good solution you will see that ecu is in problem . check pins on MAF 12v ( -ground) 5v ,5v signal . if there is no line to ecu lamp will blink.
wish you luck with that problem
