Boost pressure control valve
| Boost pressure control valve | 
| Number of windings |  | 2 | 
| Resistance per winding at 20°C
(68°F) | Ohms | 3±1 | 
| Control voltage, <2500 rpm | PWM 12 V | 90 Hz | 
| Control voltage, >2500 rpm | PWM 12 V | 70 Hz | 
| Boost pressure, bar | 
| gear | R | 1 | 2 | 3 | 4 | 5 | 
| Engine version |  |  |  |  |  |  | 
| B204L, manual, 3500
rpm | 0.54 | 0.54 | 0.54 | 0.72 | 0.72 | 0.72 | 
| B204L, automatic, 4000 rpm | 0.45 | 0.45 | 0.45 | 0.45 | 0.45 |  | 
Slightly higher readings may be obtained when checking the pressure at high altitudes. The pressures for cars with automatic transmission refer to an intake air temperature of 20°C (68°F). Slightly higher pressures may be obtained at higher temperatures.
| Basic boost pressure | bar | 0.40±0.03 | 
| Pressure switch operation | bar | 1.15 | 
| Speed limitation | km/h | 230 |
