So I recently bought a 2008 c30 after one month of use the urgent engine system service message pops up along with the red triangle mark . Replaced my fuel pump then the pressure sensor still the same codes

These are the codes any suggestions I don't wanna keep pouring money into it without a fix. Or should I just sell the car? I love the car engine and power is too good

 

Best to start googling on a P0088 and checking for related forum posts relating to high fuel pressure and PEM issues. The code is saying your fuel pressure is too high at the rail - but that doesn't tell you if its the pressure sensor or the PEM (the device that controls the fuel pump's duty cycle) the pump itself or if there's something else going on. Did you do the scan yourself or is that an Autozone print out? Common to clear codes and see what gets reset.

 

Its the Autozone print out. And the mechanic prior to that did his work and changed the fuel pump and the pressure sensor . Thanks will look into the pem and keep you posted.
