This is the car I have.
This is originally Renault 1.5 Diesel. Re-branded as Mahindra Verito.

This CAR used to give me a mileage of 56 mpg now it is giving me a mileage of 31 mpg. the dealer cannot find any problem in the car.

The ecu is also not showing any problems in the car.

So need your help in solving my problem.

Thanks in Advance

That sounds like a drastic drop in consumption has the vehicle been regularly maintained.I would be checking the injectors possibly through return spill check to see if ones sticking open,Also e.g.r. system,manifold could be choked up.
