Code 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?

Code 235 / P1092

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 you 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.

Did the code come back after clearing adaptions, I have a P1093 code which came back after clearing adaptions. Came back after about 600 km.

Same with me. Did everything as the op. I am chasing P1092 for almost a year. After clearing/resetting the fuel adaptation, it stayed off for about 1,000+ miles then it came back (. it went away a few short times by itself but mostly stay on (80%).

Help - help - help please?

You guys done a smoke test? There are a few vacuum hoses that can deteriorate and cause vacuum leaks.

Yes, there’s no vacuum leak. I am guessing that there is something borderline broken, hence the light was off for a long time. At the present, it even flipped off then on by itself but stayed on more offen. After resetting the fuel adaptation, I was happy and thought that I got it fixed but it was short lived

When was the last time the CCV and associated hoses were done?

@Crystalworks: you are good. Here is my complete story: about a year and a half + ago, my problem with p1092 started. I looked up in this forum for help and did the following repair:
a) cleaned with Techron - not resolved
b) replaced MAP - not resolved
c) clean/check DISA - not resolved
d) clean/check idle control valve - not resolved
e) new spark plugs - not resolved
f) replaced 2 front O2 - light went away for a while then came back
g) replaced 2 rear O2 - not resolved
h) found/replaced a broken rubber vacuum cap in the back of the engine - not resolved
i) smoke test and found vacuum leak. The bottom hose of the CCV was broken. Whole CCV valve and all hoses replaced. This also resolved a serious oil leak that I didn’t know the cause. SES P1092 went off for about 5k+ miles. I was happy but then it came back on and off (mostly on). No vacuum leak from here on
j) re-investigated the issue, found mihai’s suggestion so I paid for a fuel adaptation reset. The light went off for a long while then it came back AGAIN, on and off but mostly on.

Have you ever checked the fuel pressure. Constant lean condition if not vacuum or MAF related is likely plugged injectors or low fuel pressure.

is b) replaced MAP supposed to be "replaced MAF"?

^Edit: As Andrew states could be fuel pressure. The FPR is known to go bad from time to time. Not super common, but I've seen it happen.
