P2096 and P2098 codes thrown
New codes thrown on my 2002 3.0 X5 Both refer to downstream detection of a lean condition. Post Catalyst Fuel Trim System Too Lean Bank 1 Post Catalyst Fuel Trim System Too Lean Bank 2 Both O2 sensors are less than 3 months old so I do not suspect them. Wondering if this may point to a exhaust leak or what do you think? It did have another code for misfire the first time I checked the SES light but I reset it to see if it returned and that code has not come up again......yet. Thoughts?

P2098 code X5 3.0
Did you ever figure out what was causing codes. I'm having an issue with the P2098 code that keeps popping up soon after I reset it.

Sorry no,
I had issues with my VANOS and that has been fixed finally but the P2096 and P2098 codes keep coming back. The stored BMW codes are: 204 - Idle Speed (leakage air), plausibility 226 - O2 Sensor behind catalytic converter, trimming (bank 2) 236 - O2 Sensor before catalytic converter, trimming (bank 2) Did you ever get yours fixed?

So the old girl keeps throwing me curve-balls.
Checked the codes again tonight and on the OBDII: P2096 - an old friend P0313 - misfire detected with low fuel (I may have seen this one before) P1092 - This one is new (Pre-Catalyst Fuel Trim Too Lean Bank 2) Possible Causes Listed for P1092: Low fuel pressure Large vacuum leak on engine Faulty Mass Air Flow (MAF) sensor Faulty Ignition Faulty fuel injector So here is the weird thing. Went out this morning to go to work and walked around the back of the truck and the right side exhaust had a fluttering, chuffy sound while the left side was completely normal. I had heard it sound weird like that before but that was prior to rebuilding my VANOS which is now done and running excellent. After making my trip, I got out to listen again and I swear they sounded the same again? Don't know how this is possible but maybe it's ignition related? No clue since it's not giving me any more information than those codes. Most stuff I see now and hear is leaning towards bank 2 so I am wondering if that cat is getting clogged throwing all of these codes even though I have not thrown a P0420 yet. I will replace the fuel filter and check the fuel pressure as well. Then I need a way to check my cats if that doesn't help. Ahhhhh bugger..................lol

Here is a youtube video I shot just now.
https://www.youtube.com/watch?v=2RDVdoktvCU Sorry got the phone a little too close on the right side but you should be able to distinguish the kind of chuffy sound the right is making vs the left. It's a 3.0L with a dual exhaust so outside of the cat, or some sort of ignition issue, what could cause this? Should also mention that when in drive, stopped at a stop sign or whatever, the idle is consistent but kind of grumbly sounding. Can feel some vibration. Would a cat getting blocked up cause the idle to sound and feel this way? Bernie

Check out my post here:
https://xoutpost.com/bmw-sav-forums/...st-system.html and then check your car where the headers meet the first part of the exhaust system. It is said that if there is a leak there air gets sucked IN and gives that post O2 sensor false readings. Have you checked for vac. leaks yet? You make a decent smoke tester with a cigar and manual pump for $6 from Harbor freight

I will look into that before anything further. Did you get yours done and did it fix your problem? Yeah, had already smoked the engine. No leaks anywhere.

I wouldn't know if the smoker has enough pressure to push all the way through the engine and out to the exhaust? I say that because I would have thought that I would have seen smoke at the exhaust joints if that were the case. B
