Information\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eThe diesel engine requires a reliable vacuum supply for operation of the brake servo.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eUnlike a petrol engine, a diesel engine does not naturally produce sufficient intake-manifold vacuum for the brake booster under all operating conditions.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eA mechanically driven vacuum pump therefore generates the required vacuum.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eThe 7H2611931AD pipe provides the vacuum connection between the vacuum source and the brake-servo

lost when operating conditions change.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eThis helps maintain a reserve of vacuum for brake-servo assistance.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eA faulty
