Cali Smog & my 2012 X5 35d

Hello,

Looking for some clarifications if possible. Been reading the forums and I got analysis paralysis.

Been having some fun trying to pass smog and I think I'm close however I can't figure out the following:

1) Can my 2012 X5 35d pass smog test with the " PM Filter " still not set? Talking to various shops / smog testers and reading various bits on the net - apparently yes it can. One SA @ SM BMW said it won't pass as it is mandatory for " PM Filter " to be set.

I'd guess that if I can pass with this not being ready there is no point to keep reading below?

2) I had the EGR cooler replaced and then was left to drive the car so all the various monitors set. all did except for the " PM Filter ". I'd say I've managed to put about 400 highway miles and no love from the monitor. Apparently " just drive it " is the key but fear of other " stuff " having gone wrong made me borrow a plain obd reader and a Carly to see what else might be broken and found:

From the reader:
  • P2201 - NOX Sensor Circuit Range / Performance Bank 1 Sensor 1

From Carly:
  • 474C - Exhaust fluid error
>> this one is an old one as the dealer serviced this - so likely just not cleared after service? probably not a problem.
  • 4B6A - Nox sensor before denox cat - Plausibility
  • 4C7C - Reducing agent metering valve, activation
  • 46B4 - NOX Sensor before denox cat plausability nox

Anything in this list that could prevent the PM Filter monitor to set?

TY!

All of those are downstream in the exhaust from the DPF. So I would guess that they have no effect on the DPF stuff.

I would guess that, for whatever reason, no regeneration has yet occurred. My 335d does one about every tank (500 miles or so). You might try to force a regen with carly and see what happens to the pm filter.

My guess is you need NOX Sensors replaced. Should be covered under extended warranty.

TPMS Light On

Hey guys,
Does anyone here knows if I could pass smog with my TPMS warning light on ?
I donít have any SES light on at all but only the TPMS light keeps blinking and gives me warning sound. The dealer advised to rotate my tires and possibly replaced the sensor.
I just want to know if I could pass smog and if the TPMS light would prevent me to pass ?
This might be a silly question. Thanks

It has been a while since I had to smog a car in CA (not since '92), but I do not remember the inspector getting in the vehicle to notice any of the warnings. If they do, perhaps they will fail for safety issues, but the TPMS in the tires has nothing to do with your emissions systems.
