I think this seems to be the biggest concern that Maruti might be facing.

Other OEMs, (except Honda ??) had developed their Diesels for Euro 6 that came into force in 2014. US and Korea also follow similar emission norms. (not mentioning Japan as diesel percentage in passenger cars is comparatively small). So, the OEMs which had/have diesel engines in overseas markets, have more time and volumes to ammortize the design & development cost.

Whereas, Maruti never planned diesels for Euro 6 markets, so now all the BS VI upgrade costs have to ammortized over Indian volumes (that too 1.5LD version only). This makes cost impact per engine (vehicle) high, putting Maruti in a soup.
