| Check | |||
| 7 | Press compression recorder (01) on tapped bore of spark plug for first cylinder | ||
| 8 | Crank engine with contact switch for compression recorder (01) until a pressure rise is no longer indicated on compression recorder | ||
| 9 | Carry out testing procedure in the cylinder order on remaining cylinders in the same way | ||
| 10 | Compare measurements obtained with permissible pressures | Compression pressure, installation tolerance or new value | *BE01.00-P-1001-01B |
| Compression pressure, permissible difference between individual cylinders | *BE01.00-P-1002-01B | ||
| Compression pressure, wear limit or limit value | *BE01.00-P-1003-01B | ||
| 11 | Check for cylinder leakage | AR01.00-P-1300EWS | |
| 12 | Install in the reverse order |
