The following codes came up when BMW scanned the X5 (2002 4.4)
1.p1159
2.p2187
3.p1161
4.p2189

The service department said there were some damaged vent hoses in the rear of the engine $400 estimate. It didn't seem right anybody know the codes or any similar problem with vent hoses.

I had AutoZone run a scan and they came up with two codes
Fuel air metering and fuel stepper motor.

Any help would be greatly appreciated
