Thanks for answering - Yes , I did look at your thread and used to check few thinks..
O2 - pre cat sensors are new -- few weeks old.
O2 - after cat - never change - my car has close to 160,000 miles - no problems , starts ok - MPG lower than used to , but not too much - MAF close to two and half years old , will try to clean it. .. But since millage is high in my car I am considering changing the two catalyst converter , not for BMW ones but for the aftermarket (BAvarian and Turner - ad for $400 each) , they look ok maybe a little better than stock ones. also change the after cat sensors

What's interesting is that my car started getting the P1192 code right after I change from stock air intake filter to a K&N filter....sometimes the code dissapears , then comes back when the car drives on bad roads

Vacuum test was ok -- did smoke test and no leaks...

Yeah, keep me in the loop... I also found a broken hose to my secondary air injection system which one of my mechanic friends thinks was causing a vacuum leak elsewhere, but I'm not sure what else it's connected to? But that code is the one that has consistently popped up, so hopefully with the vacuum hose fixed and all the O2 sensors replaced it will stay off!

There is only one way to find out, take your boobs poses and examine them very carefully, just the littlest crack can set off the code. Trust me, I know this from experience, and I have replaced all my boots, and have been good ever since.

I think he is referring to the intake boots that connect the air filter to the throttle body?

Suggest you read the first link below in my signature as well.

Yeah, the secondary air injector hose runs from the far left side (standing at the headlights looking down) all the way behind the engine, quite frankly a huge pain to get to. Removing the cabin air filter housing (nearest the windshield) gives you room to get a mirror and a flashlight back there to help, but again, huge pain. There are a bunch of hoses back there that all have the potential to be cracked/disconnected causing leaks, but I'm not 100% sure that this is the source of our nemesis code... keep me updated and I will do the same for you! And out of curiosity, is one of your symptoms very "jerky" driving in regards to acceleration especially when very cold? Hope one of us can solve this mystery soon!


PS The LENGTHY post that jfoj has after his signature is a great tool, but I don't see code P1192 mentioned in there, so I just messaged him and will let you know what he says back to me!

P1192 Update

P1192 code continues - after 160,000 miles performed the following changes.

New Fuel Pump - Recommended -
New Catalytic Converters _ Aftermarket from Bavarian Auto. $400.00 each. If you want legal headers, buy this one.. the car sounds like new and gave my UUC TS3 exhaust a new sound and a header sound like when you hit the gas, the car screams like a V8 on steroids.......

But the P1192 continues ..... A good friend told me that most cars running with the AFE intake (like mine) will run rich and recommended to get the A Autowerke programing to fix the problem...

So- Next Mod.. A Autowerke software -- Will update when done.

MAF - changed at 80,000 miles

Well I did actually get the p1192 code to go away and stay away, and although I don't know for sure which "repair" fixed it, my hunch is that it was due to one of the vacuum lines between the rear of the engine and firewall being disconnected. It stayed after replacing all four o2 sensors, but I don't know if the software might fix it as well. Hope you get it figured out!

Thanks my friend ---- honestly, just by looking at your picture I have no idea what part is it, but I will follow the vacuum lines on that side to look for similar part.... If you have a picture of your engine and just point to the area I think that will be perfect.... but again , Thank you for your help..

Best way I can describe it is to say it's oriented in the picture as if you were sitting in the drivers seat and your dash and firewall were seethrough, it would be right in front of you a little to the right. If looking at the engine (standing in front of the car looking down), if you are looking at where your intake boot ends (at the throttle body) then the left side of this picture would be right above there, and the front of the picture is what you can't see because it's facing the firewall. The tip of my screwdriver in this picture is pointing to the nubs you see on the left side of the previous one. Hope that makes sense, and hope that helps, I know this can be confusing so happy to do what I can!!!

Got it now - perfect thanks - from that point one hose goes to the firewall and the other one (the thin one) goes to the intake boot... can't see where it goes under but it will be quite a job to clear that area... I will let you know... When you said yours was disconnected - what did you mean?? broken??. off??,

Again -- thanks for your help..

Mine was all funky, just looked like someone had a bunch of them unplugged and just stuck em where there was an open hole, but the one I think "did it" was the little black and white cylinder with a hose running into each side, the white side was unplugged so I just had to reconnect it. While you're back there fooling around, I would highly suggest running new hose (fairly cheap) where ever you find hose that even COULD be going/gone bad. It's a pain to get back there, so once you do I would make the most of it. There's a lot you can remove pretty easily to get a little more access (cabin air housing, panel behind that, upper and lower boots, and heat shield on the right). And lastly, a flashlight and telescoping mirror will be your new best friends if you have them ;-)

You're welcome for the help... people helped me so it's my pleasure to be in the place to "pay it forward"... hope it all goes well and easier than you expect!
