Pic. 2.44. Fuse box
Remove the SD34 fuse from the fuse box on the right side of the front panel (pic. 2.44).
Note: Removing fuse SD34 interrupts power to the fuel pump control unit.
Note: Measure compression with a compression gauge.
Note: The operation of the compression gauge is described in the relevant manual.
Scroll the starter until the compression gauge stops showing pressure increase.
Compression:
- new engine - 10–15 bar overpressure.
Maximum tolerance 7 bar overpressure.
Permissible difference between the individual cylinders is 3 bar.
Screw in the spark plugs with a spark plug wrench and tighten them to 30 Nm.
Further installation is carried out in the reverse order.
Interrogate the fault memory, eliminate existing errors if any, and then clear the memory.
After clearing the fault memory, you must create a readiness code (Readinesscode).
