Idling compensation Volvo 240 (B230K)

Rough idle, an rpm drop when the engine is cold or when electrical loads are switched on can point to wear in the idle compensation on the 240 with the B230K engine. The solenoid valve that controls the extra air volume is a common check point, and the connections and coupling pieces should also be inspected for cracks and leaks that draw in false air.

This group includes parts belonging to the idle control: solenoid valve, connection, coupling piece, wave washer and protecting casing. Since the B230K is a specific engine variant in the 240 series, the code determines which parts fit – always check the engine designation against your car before replacement, so that the valve and connections seat correctly against the intake and hose routing.
