Faced DEF issue on my Thar during a trip: How ASC fixed it in an hour

After completing it they took it for a test drive for around 5-6 kms at higher RPMs.

BHPian batish recently shared this with other enthusiasts:

Update on the E22 DEF Dosing Malfunction error: This progressed quite early. Had to take a detour and drive to MASS. Nearest one was at Reckong Peo. Took an appointment with them in the morning itself, and they told me to bring it in.

They poured in some water on the housing to cool it down so that it can be opened.

The temperature can be seen after connecting their laptop. Took them around an hour to fix it. These are the DTCs which their laptop reflected.

After completing it they took it for a test drive for around 5-6 kms at higher RPMs. Then only the E21 error light went away which made me realise that they can reset E22 from their laptop but for E21 the system itself diagnoses it and the solution to it is driving at higher RPMs before it turns to E22, which even the MASS validated.

I still cannot comprehend how this fuel guzzling equipment are helping the environment.

BS6 reduced the average fuel economy for most vehicles, brought in DPF complications for diesels and turbo petrols anyhow don't give mileage as compared to their diesel peers.

So, how exactly is this helping environment I fail to understand.
