43 001 53	Insufficient vacuum in system. Occurs particularly following cold engine start with a large number of loads switched on, on vehicles with air conditioning in operation and on vehicles with automatic transmission shifted into gear.	1 Check vacuum at idle with all loads switched on, on vehicles with automatic transmission shifted into gear. If the vacuum does not reach a value of at least 0.45 bars after 5 s at the latest ↓	AR43.10-P-0023A
		2 Replace vacuum line	AR43.10-P-0350A
		3 Replace crankcase ventilation hose from oil separator to air cleaner
		4 Routing connection hose between vacuum line and crankcase ventilation hose
		5 Attach connector hose at suitable points with tie straps, clips, hose bracket, cable holder and/or sheet metal clips.
