I wanted to thankyou for your write up. I had a blown HDG and after getting the engine together, I ended up with the exact sames codes. I had a spare O2 sensor, and swapped it out in 15 minutes and the car works perfect now.

P1189 P1073 - I think was o2 sensor bank 2 precat not tight

I'll update this post later, we'll see how it pans out. It could have been the previous o2 sensor wore out but we'll see. One thing of interest is the code for the cel was 1189 and 1073, suggesting maf, but the scan tool clearly showed bank 2 o2 sensor bad, yet there was no code thrown for bad o2.
Many years later & now I get 1189 $ 1073 again. I forgot I wrote this, looks like I may need a new o2 sensor bank 2 precat. Also since above I replaced the head. A coolant leak does indeed kill o2 sensors.

Update - I changed out the O2 sensor and found that it was not tightly screwed in. Not wiggly, just not tight. My 1189/1073 this time was intermittent, happened only at rev above 2500, more often when going up a hill. I'm thinking that unders such conditions it may have have more exhaust pressure and somehow allowed air into the system? I changed the O2 sensor out anyway, maybe also it was getting lazy in switching. Anyway it test drives ok and seems to have more power, let's see how it goes.

For those who want so replace Fuel Pressure Regulator, it is about $50-$60:

---> 06/1996: 13531729319
---> 09/1997: 13531436110
---> 1999+ models have FPR built into the Fuel Filter itself.

Anyway, for 1996-1998 models, in contrast to realoem diagram (which showed FPR next to the Fuel Rail, which is incorrect), the FPR is actually located next to the Fuel Filter, it is connected to the vacuum hose.

Early '97's are different

CN90,

My 6/96 production date 528i indeed has the fuel pressure regulator up in the engine compartment along the fuel rail. Underneath the car, I only have a fuel filter, not the 3/2 valve and FPR setup that's depicted in your photo.

Interesting,

So the BMW engineers moved the FPR down there later...
