Oh I am sure if I drive a 5 ton forklift on it, it will crack!! Or if by throttle body we mean intake boot/rubber gasket/intake manifold/valve cover/maf...sure it can happen!

I promise to update you all. Thanks again for all your comments and advice.

I have no idea what it could be as the car seems to be running perfect with no noticeable issues. I had a 335i for 4 years and this one seems to run better than that car... damn turbo engines. I guess what I'm saying is that if the light wasn't on I would have no idea that there was a problem. No stalling, no smoke, no weird idling etc.

Anyhow, I'm taking it to my mechanic who is a friend of mine, he also owns a bmw and is going to give me a written print out of what codes are showing.

Thanks for the etest link.. I'll look it up tomorrow when I'm more awake.

Night nite all...

Ok so I couldn't sleep.. the suspense was killing me this is what I found.

It was tested in June this year by 'Illusions Automotive" in toronto on three different days all using the OBD. All 3 tests failed with a reason of 'not ready' until it was tested using the 2speed idle tailpipe method, in which it passed.

How could it have passed with the tailpipe test if there was obviously an issue. Should i contact the ministry and report this facility as I feel something fishy is going on..

It obviously has a pre existing condition that was not taken care of. Seems like i have some amunition to bring with me tomorrow when i meet with the dealer.

There's a loop hole for dealers. Resale cars can do the 2 speed tailpipe dyno test if it fails the OBD test twice but only if the engine light isn't on. But I believe you said earlier that the engine light was off... so they likely reset it for the OBD test (the test requires pictures) and failed twice (or 3 times in your case) then used the loop hole.

this!

and you are now learning about the new emissions test. A car can technically be good out the tailpipe but if the ready monitors for the obd arent ready(which they arent right after a reset) the car will fail the scan method. Also will fail the scan method with (1-2 I forget exactly depending on year) codes.

even though out the tail pipe things are ok.

vice versa...as long as the computer is happy you can have anything coming out the tailpipe these days
cash grab scams yay.



buying a used car from the majority of these shady dealers is a bad idea.

So I had my car checked by my mechanic this morning.
Diagnostic showed codes P0444, P0171 &P0174


Any thoughts to what the exact issue is.

It definitely shouldn't have passed emissions.

P0444
Evaporative Emission System Purge Control Valve Circuit Open

P0171
System Too Lean

P0174
System Too Lean

That's just from a google search - the wrenchers on here will have to let you know that they think...

P0444 could be a loose gas cap, but it's probably a cracked tube in the whole mess of the CCV/intake system. ALL E46 will experience vacuum leaks/lean codes at some point. It's a big job to replace them all. Took me all day to do it (mostly because updated dipstick tube would NOT seat properly... MF!#@@!)

I'm relieved its not anything more.. and driving wont hurt the engine till i can figure out what part is really affected.

I went back to the dealer today with my knowledge of the failed emissions tests and the codes that were read and on paper by my mechanic. Told them I spoke to OMVIC and they suggested i give him the chance to do something about it before i escalate the shit out of this. He suggested I bring it to his mechanic tomorrow and have him look at it and see what they can to do fix it.

So for now I don't have to go postal on anyone and my car is not in grave danger of dying or causing engine damage in the meantime. I have a feeling I'll get the runaround from him but i'm keeping my fingers crossed for now.

THanks again for all the info and advice.. you guys all rock.

Well... you should be okay as long as it isn't too bad, but lean conditions can cause engine knock, which can cause damage to your engine.

Probably ok if you're engine isn't going into limp mode or running rough.

Your dealer is working with you through his own mechanic to resolve the 3 issues you have, you have OMVIC to go back to if he gives you the runaround.. just a bit of inconvenience and towards the end, I am sure it will be sorted out..
