injector /compression issues

[chris s]

Hi All i am hoping you can give me some advice please 

I have another major issue with my recently purchased X type 2.2 diesel 59 plate

The other day the car started missing and making a very loud knocking noise i originally thought it was a air flow issue but Green flag mechanic says its an injector issue causing compression problems the dealer i bought the car from are being really un helpful I have major health issues and rely greatly on my car so desperate to get it sorted but dont want to be ripped off again

Some one said these engines are known for over metering and sending too much diesel to the injectors causing them to blow Would this be true? If so would anyone know what i should expect to pay to cure this

Thanks in advance
