A rough idle, a check-engine light or high readings at the emissions test can point to a sooted-up EGR valve or a leaking vacuum control on the B230K engine. This category gathers the parts in the exhaust gas recirculation system for the Volvo 240 with the B230K specifically, where the valve routes some of the exhaust gases back into the intake to lower the combustion temperature.

The group includes the EGR valve, vacuum booster, coupling piece, connector, nipple, hose as well as hex and fitting nut. During a rebuild it is common to check that the diaphragm in the vacuum booster is sound and that hoses and nipples are not cracked – small vacuum leaks often cause uneven running. Since the parts are tied to the engine code B230K, it is worth confirming that the valve and connections match your engine before replacement.
