My car MH14CK5298 was damaged either intentionally or happened due to rough handling at service center and the blame is now put on our head due to the fault of service center folks which is unacceptable. they are demanding Rs 49523/- for ECM when the car was perfectly fit.
Kindly help resolve the issue as it brings bad name to the company as well as dealer. the service staff programmed it for malfunctioning
