Hello,
In no way is the Clutch Plate and pressure plate cost Rs 30,000 unless the Flywheel component is changing
Also - Flywheel is much heavier disc and is expected to last much longer unless been abused by very bad driving where in the car driven with
> Hand brake up for long distance
> Driven on speed with Clutch been engaged too for a distance
Suggest to ask the workshop complete breakup with parts
> Clutch Plate
> Pressure Plate
> Release bearing
> Labor charges
> Inspect Flywheel in person for potential sign or problem
Hope should help !!
