Tightening Specifications
After the high pressure line assembly, and when installing a new short engine, it is particularly important to tighten the fuel injector tensioning clamps to the previously mentioned tightening specification. Refer to OVERVIEW - FUEL INJECTORS . Only tighten the tensioning claws >>hand tight<< after delivery when assembling the high pressure lines in order to align the fuel injectors. Engine damage may occur if not observed.
After installing new parts (engine/partial engine, cylinder head, camshaft housing or turbocharger), the oil pressure regulation is to be limited to the high pressure stage for approximately 1000 km. From this, the higher friction is taken into account when breaking in new components, and the optimum removal of particles from the initial wear in is ensured. To do so, connect the Vehicle Diagnostic Tester, switch on the ignition and select the following menu items:
