Code 235 / P1092

Hi guys, i have a 2006 X5 3.0i 90k miles. I have this code that i am trying to get rid of and nothing i did so far helped me. I did some research on the internet and i have found only one success story on resolving this(by changing one of the o2 sensors), but that fix didn't help me.

One thing i have to mention, i am not sure if it has anything to do with this, but right before i started getting the code i changed some components to the cooling system(thermostat was stuck on open); i changed thermostat, water pump, expansion tank; on top of that i added one can of liqui moly jectron when i filled the tank.

What i did so far trying to fix this:

changed upstream O2 sensors
changed intake boot
changed disa
changed spark plugs and coils
changed valve cover gasket.
cleaned maf

Car runs great...smooth, no power loss, very good MPG 20-21.

Anyone else had this issue? if so, how did you fix it?

Here's the list of suggestions :

Low fuel pressure
Large vacuum leak on engine
Faulty Mass Air Flow (MAF) sensor
Faulty Ignition
Faulty fuel injector

Looks like to addresed most except the injectors and fuel pressure.

Test fuel pressure to make sure to have enough (50psi or so) check under load (a good punch of throttle should work without driving ) it should not dip more than a couple psi.

If psi stays high it's got to be the injectors you addressed everything else I think.

SOLVED

I cleared the adaptations with inpa. That's all i had to do...wasted months of troubleshooting and never crossed my mind that after clearing the code, i should try to clear the adaptations.
