BS6 requirement of DEF on my Seltos has killed my love for diesels

It defeats my intelligence as to why was a provision for SCR and DEF not provided for sub 2.0L diesel cars in India.

BHPian Dejay recently shared this with other enthusiasts.

I belong to the dying breed of car owners who chose a diesel car since the advent of BS VI emission norms in India. If you narrow it down to diesel car owners below 2.0L engine then I am sure there are gonna be much lesser pals for me. Nevertheless I am a die hard fan of diesel cars and never regretted it until....

While choosing my diesel car little did I know about the importance of a magic fluid called DEF (Diesel Exhaust Fluid) and a process called SCR (Selective Catalytic Reduction) and its most critical function in diesel cars with the advent of BS VI emission norms. Add to that the substandard BS IV or below fuel that is being sold at the fuel stations all over India. These two things contribute to the lack of practicality of owning a diesel car in India (sub 2.0L engine).

So I paid the price for it as all the hazard lamps in my car started blinking because the BS IV fuel got clogged in the filters of my BS VI diesel car. The solution offered at the KIA service station was even more bizarre. They told me to drive the car for 2-3 hours over 3000 rpm.

Nevertheless, the issue was resolved but I understood that this was a problem that is going to keep coming back to me. It defeats my intelligence as to why was a provision for SCR and DEF not provided for sub 2.0L diesel cars in India. For the uninitiated, let me explain: The function of SCR and DEF is to dissolve the dirty gases, NOx, and particles that are released through the exhaust. In India, only vehicles that are 2.0L engine and above have a provision for SCR and DEF.

So I end up with a 1.5L diesel car with no provision for SCR/DEF which is a horrible situation. So if you are planning to buy a diesel car in India, please go for a one with 2.0L engine or above. I invite all my fellow 1.5L diesel car owner pals to come share with me your grief or advice to handle this situation.

My love story with diesel cars has ended. I have already used 3 diesel cars so far (Maruti Swift Dzire 1.3L with Fiat Multijet engine, Volkswagen Polo 1.5L with TDI engine, KIA Seltos 1.5L with CRDi engine). I have already decided that my next car is going to be a petrol car. Just like most love stories, mine also does not have a good ending. But what fun is there in a love story with a happy ending.
