TAKE A SEAT

IN HIS LATEST ARTICLE, JAMES DILLON ADDRESSES A PROBLEM WITH THE COMMON RAIL DIESEL ECU ON A 2010 SEAT IBIZA MY. This month I am covering a problem with a SEAT Ibiza 2010 MY which was initially presented with a flashing MIL and the vehicle was unable to rev to more than 2000 rpm. The Siemens/Continental Common Rail Diesel ECU had set a trouble code for Fuel Pressure Regulator Short to Ground and Fuel Pressure Regulator Electrical Malfunction (Engine Bay Fig. 1). This job seemed to look straight forward at the outset. A quick visual inspection of the diesel control system showed that it employed a technique known as two point fuel control. This is where the system 'throttles' the fuel intake to the high pressure pump via an inlet metering valve, and may also control the rail pressure via a pressure control solenoid.
