Compression test

Special tools:

999 9689 COMPRESSION METER See: Tools and Equipment/999 9689 Compression Meter 
115 8540 EXTENSION See: Tools and Equipment/115 8540 Extension 

Ignition system

A check for cylinder leakage (also called "leak down") can be carried out instead of a compression test. Cylinder leakage test See: Engine, Cooling and
Exhaust/Engine/Testing and Inspection 

Caution! The ignition system operates at high ignition charges and produces dangerous voltages in both the low and high voltage circuits.
There is dangerous voltage throughout the entire ignition system including connectors etc.

Conditions

Note! The engine compression must always be checked with wide open throttle (WOT) and engine at operating temperature.

Preparations

Remove:

-

the charge air pipe over the engine to improve accessibility.

-

the upper timing belt cover.

-

the cover over the ignition coils.

-

the ignition coils.
