Some codes

Hi guys, I'm having some problems with my 1998 BMW 528i. I got this code, can you guys help me? I searched but I didnt get it.

P1250
P0154
P1189
P1519
P0170
P1188
P0134
P0173


I think most of them its o2 sensor and maf sensor right?

P0134 - O2 sensor
P0154 - O2 sensor
P0170 - air-fuel computer error - possibly caused by bad O2 sensor or MAF connector; also vacuum leak or cam/crank sensor
P0173 - air-fuel computer error
P1188 - Fuel control (bank 1) - another air-fuel error - possibly MAF or air leak intake hose
P1189 - Fuel control (bank 2)
P1250 - Fuel level too low (also could be failing fuel sensor)
P1519 - Camshaft position actuator (bank 1)

people were reporting this problem after changing out the head gasket or messing with the vanos timing. many reported that re-adjusting the vanos timing eliminated this code

The code means you don't have enough (or any) VANOS travel. You need to retime your cams and check your vanos advance with air pressure.

Personally, I wonder if it would be useful if the OP cleared the codes, stuck the scanner in the OBD port and then drove for a couple of miles. Stopped. Checked for pending codes, and then, worked on the FIRST code that is pending.

Would that be a good way to reduce the plethora of codes to something more manageable?

That's kind of what I did when I debugged mine:
- Does the order of the misfire OBDII DTCs diagnostic trouble codes actually matter (1)

Yes, I start getting of these codes after changing the head gasket.

I didn't know you could CHANGE vanos timing!

I fixed all these codes by changing mass air flow sensor and one o2 sensor and unbelievable increase in power!
