•1dI have a budget of ₹25 lakh, and my daily driving is around 40 km. I am considering buying the Mahindra XUV 7XO, as I want a 7-seater with excellent features and safety. However, I am somewhat concerned about the DEF issue. What should I do?

Autocar India
The DEF or DPF, diesel particulate filter issue typically arises when the car is used only for very short drives or constant slow-speed city usage. All engines equipped with a DPF undergo a DPF regeneration cycle to avoid clogging. This process happens automatically when the exhaust temperatures rise high enough, basically when the car is driven for at least 20 to 30 minutes at speeds of about 60 kph, typical a highway drive. This process generally needs to occur once every couple of weeks. So if you have this kind of driving pattern, you should be fine.
If you do not end up achieving this, you will receive a prompt to run this cycle or even a parked regen cycle, where you would have to keep the car in an open space and follow the prompts on the screen, which essentially would keep the car idling at a higher speed for up to 30 minutes.
