Thanks for your information, I owned second hand Tata hexa 42000 km driven and come to know about its EGR issue of the other owners can you please tell me how we can detect prior to it malfunction so that can get it cleaned in time because what indication you have told is same as clutch plate failure to which I come across a few days before and how can we avoid it's failure.
EGR system is fitted in a vehicle only to meet pollution norms applicable as per guidelines of Govt of India. At present BS-VI norms are applicable. Mainly NOx are controlled through it.
