I visited the ASC and got around 4 litres of DEF topped-up. Ran an OBD scan and there were no further errors.
Then did a 500 km highway trip - so hopefully I am sorted for the time being.
The entire DEF thingy is a bit of a hit-n-miss. But constant city usage at low rpms will definitely lead to DEF/DPF warnings. |
That highlighted part in your message - that is normal! It just means that the vehicle encountered an incident (in this case, maybe higher than threshold of particles in the filter) and acted on it.
This keeps coming even in my Thar, at times even during highway runs - and I started noticing this only during after-dusk drives coz the alert is barely visible in daylight.
Nothing to worry if this happens!
The one Thar that I know of belonging to a friend - running in Ooty, which kept getting DPF related errors with the vehicle going into limp mode - this was caused by wiring issues, and was fixed with a wiring harness replacement for the exhaust.
Those who have a Diesel Thar in the forum - has your jeep gone into limp mode because of DPF? If so, was the ASS able to hook up the scanning tool and see what is the reading on the density of Diesel exhaust particles?
Even during an idle test, my vehicle barely went over the minimum threshold before the DEF douses it. Quote:

Every time I heard this chime, I got confused and used to check whether I am above 80 or parking brake is engaged or seat belt is buckled.
Recently I caught this in MID screen. I am doubting that it could be an early sign of DPF clogging which would need attention. | Quote:

That alert coming and disappearing is normal!
And the DEF tank is 20 liters, and my Thar drank about 8 liters in the second service at 9350 KM. So I doubt if it is related to DEF either - it is just the electronics doing their work - if the alert stays on and the engine goes to limp mode - then there is a problem! Quote:

Where will all the already delivered Thar diesel owners go in the city if this is the case. Iam totally confused. If this issue is for real, then M&M should take back all delivered diesel Thars and exchange them with Petrol makes. |
I don't think it should be! As long as the engine is not switched off, even in bumper to bumper traffic, the exhaust system will do its work. About 300 KM of my 2000 KM city drive is in Bangalore. Another 750 KM within Hyderabad, 400 KM within Madras and 500+ in Coimbatore.
I am yet to come across a Thar that has gotten DPF issues coz of actual DPF issues (the one I know of personally, and another from the forum - where we do not know the final update - is wiring related!).
