my X5 (E53 4.6 2002) isn't running that well and on further examination I've found that the "Crankcase Vent Hoses" are totally U/S.
The parts I'm trying to sauce are as follows
Vent hose 11 15 7 566 837 – x1 off
Vent hose 11 15 7 566 838 – x1 off
Hose clamp 11 63 1 716 970 – x2 off
Hose clamp 64 21 8 367 179 – x1 off
Hose clamp 07 12 9 952 109 – x1 off
I know I can pass GO and go straight to jail (BMW MAIN DEALERS)


but can anyone suggest alternative suppliers to get the parts at more affordable prices?
thanks
