I'm in Australia, I don't know if this would benefit you but i took it to a place called ASV european auto.

The service for the injectors is $300AUD + fuel filter $76 + clutch $650.

Im sure also it is the injectors caus the noise is not from underneath but on the top of the engine. He checked the computer and all electrical fine but that noise is injectors related, so gonna get them serviced and see how we go.
