1 Turbocharger position sensor 2 Turbocharger vacuum unit 3 Variable geometry turbocharger On some versions with variable geometry turbochargers, a turbocharger position sensor is located at the end of the vacuum unit. This position sensor further optimizes the boost pressure control. This has a positive effect on exhaust emissions and fuel consumption. The position sensor… Read More »
Function The BARO sensor is located in the PCM and measures the ambient air pressure. The further functioning is similar to that for the Bosch common rail system. Note: some versions (with fixed-geometry turbocharger) are not equipped with a MAP sensor for detecting the actual boost pressure. In these versions, the BARO sensor signal is… Read More »
Note: not all versions are equipped with an IAT sensor. For these versions the intake air temperature (downstream of the turbocharger) is calculated by the IAT sensor integrated in the MAF sensor. Function The IAT sensor is designed as an NTC thermistor and is located in the intake tract, downstream of the turbocharger. It detects… Read More »
1 MAP sensor 2 IAT sensor NOTE: Not all versions are equipped with a MAP sensor. In these versions, the boost pressure is calculated from the engine speed, intake air mass and BARO parameters. These versions are equipped with a fixed geometry turbocharger with a pneumatic bypass valve (waste gate). The MAP sensor is located… Read More »

1 Fuel injector 2 Identification number Inside the hydraulic servo system there are various restrictions with extremely small diameters which have specific manufacturing tolerances. These manufacturing tolerances are given as part of an identification number which is located on the outside of the fuel injector. To ensure optimum fuel metering, the PCM must be informed… Read More »

The exact procedure for the correct installation of the sealing rings and the plastic rings can be… Read More »
NOTE: The bending radii are exactly matched to the system and must not be changed. NOTE: After disconnecting one or more high pressure fuel lines, these must always be replaced. Reason: The reason for this is that leaks can occur when re-tightening, due to distortion of the connections of the old lines. The high-pressure fuel… Read More »
