Any good, trusted and experienced Diesel Car Mechanic in Bareilly??

I need to get my i20 elite diesel 2016 model serviced.

It'd be a major service as the mileage has crossed over 1,25,000 kms. I need to get my EGR body and engine manifold cleaned.

So I need a expert in diesel car enignes who has such experience as this works requires high skills. I tried at some local garages but no luck.

Pls don't tell me to go to Hyundai workshop as I have some past troubles with them.

Thanks for your help!!!
