Pressure/Variation
| Minimum Compression Pressure Test cylinder for leaks if minimum compression pressure is below specification. Since July 1987 the engine number is followed by the compression ratio. It is thus possible to clearly distinguish from the outside between a normal and a low compression engi | Normal Compression Engine | 8.5 Bar (bar) |
| Low Compression Engine | 7.5 Bar (bar) | |
| Permissible Differenece between Individual Cylinders (Max.) | 1.5 Bar (bar) |
