I just got the quotation for parts needed to replace in my 06 Hyundai Matrix Crdi (from Hyundai Global City), It comes out at

P186,000. I need to replace the Rail Pressure Reg. Valve, Vaccuum Pump assmbly, High Pressure Pump, Swirl Actuator, A/c switch and Cluster Assembly. This is what i need if i want to get the matrix back to normal.
I highly recommend The Hyundai Global City Service Center, they did a great job getting my car running, even if it is not 100% normal yet at least i am able to use it around town ( they recommend not bringing it to long trips out). They solved it by disconnecting the Crdi. I cannot exceed 3000 rpms though.
If you need service call Mon at Hyundai Global
