Danger | Risk of death when working on component parts and systems with U >= 30 V alternating voltage (AC) or U >= 60 V direct voltage (DC) | Do not touch damaged or defective live component parts and lines or non-insulated electrical connections and lines. | |
Danger | Risk of explosion caused by fuel igniting, risk of poisoning caused by inhaling and swallowing fuel as well as risk of injury to eyes and skin caused by contactwith fuel. | No fires, sparks, open flames or smoking. Pour fuels into suitable and appropriately marked containers only. | |
Warning | Risk of burn injuries, suffocation and poisoning when working on the exhaust system and the components connected to it. Risk of suffocation and risk of poisoning caused by inhalation of gaseous and solid components of the exhaust. Risk of poisoning caused by skin contact with solid components of the exhaust. | Wear protective clothing and safety glasses. Use the extraction system. Move people out of the hazard area. | |
Warning | Risk of injury. Skin or eye injuries may result when handling hot or glowing objects. | Wear protective gloves, protective clothing and safety glasses, if necessary. | |
Caution | Risk of injury caused by scraping or cutting body parts on sharp vehicle parts | Always wear protective gloves when working on or near sharp and non-deburred vehicle parts. | |

1 | Remove spark plugs. | ||
| Check | ||
2 | Connect endoscope (2) to light projector (1). | ||
| 000 588 01 21 00 Endoscope | ||
3 | Move piston of cylinder to be checked to bottom dead center (BDC). | ||
Firing order | |||
To do this, turn engine at the center bolt of the crankshaft in the direction of engine rotation and observe firing order. | |||
4 | Inspect cylinder with light probe. | To do this, insert endoscope (2) through the spark plug bore into the cylinder to be tested. | |
5 | Check cylinder barrel. | ||
Notes on the assessment of pistons and piston rings | |||
General information on inspecting cylinder walls | |||
If there is 'scoring' (wear to the cylinder), the cylinder barrel has become rough and honing marks are no longer visible. | |||
If the condition of the cylinder barrel is not clearly recognizable, | |||
| |||
Check compression pressure. | |||
If the condition of the cylinder barrels still is not clearly recognizable, | |||
| |||
Check for cylinder leakage. | |||
If the condition of the cylinder barrels on a cylinder of the left cylinder bank still is not clearly recognizable, | |||
| |||
Remove the left cylinder head. | |||
If the condition of the cylinder barrels on a cylinder of the right cylinder bank still is not clearly recognizable, | |||
| |||
Remove the right cylinder head. | |||
6 | Pull endoscope (2) out of the cylinder. | ||
7 | Perform check of other additional cylinders. | To do so, repeat operation steps 3 to 6. | |
8 | Disconnect light projector (1) from the endoscope (2). | ||

Warning | Risk of accident from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running. | Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts. | |
10 | Perform engine test run. |
