I hate to keep asking the same quesitons in differnet places, but Im not getting any response. So, I'll try to reword it and hopefully some folks will chime in.

I doubt Im the first and only person to go and get an inspection done on a 335 with O2 Sims.

- If you have successfully done the inspection please respond here.

I've had 3 failed attempts (2 recorded by NC), one with a map that should have worked. Shiv, bless his soul has been trying to help me out. I appreciate it very much. I have one more map to try.

I dont have the opportunity to screw this up again unfortuantely. Another strike and I am out, stuck with a $250 fine and still wont be able to drive the car.

Lastly, even if you dont need to get your car inspected, and you DO have SIMs. Can you do me a favor and check to see if you get o2 readiness on your vehicle?

Does ANYONE know how to verify "o2 readiness" on their code reader? I have a crappy reader right now, which wont allow me, but I will get a good one tomorrow. I was hoping someone , somewhere has done this as well.

Regardless of if you need an inspection or not, if anyone out there has DPs and Sims can you do me a favor and check your car for o2 readiness?

Once I can verify the O2 system is "Ready" then we're good to go.

You need to get Auterra Dynoscan to verify it....

[M3to335]

Fancy. I doubt any of the guys at work have one of those to borrow. So I suppose a run of the mill scanner wont work?

Do you live in an area requiring an OBD scan?

Yep. They dont do sniffers, instead they use an OBD scan.

I am not sure what else you can do really. The next step, unfortunately, would be to reinstall the stock DPs and get the inspection done....

[kenwelch]

This is a software and cable package that will allow you to turn a PC into a scantool. You can then read the O2 values and readiness moniters for OBD II vehicles. Cost is $249.00 and you provide the laptop or move your desktop to the garage.

There is also an advanced European package (that costs more) and includes BMW specific test capability.

And you have DPs and Sims as well?

I couldn't get my DPs installed because I couldn't get the top nut off of the DP hanger. I still need to try again soon....

I wish I could help you some more man....

Shiv should be able to solve your problem with the new V3 features and new maps....

Yup, thats what Ive got.

Your best bet is to keep working with him and try to find someone with that dynoscan software....

[M3to335]

K. Untill then.

Im still waiting for O2 sim folks to chime in.

I thought you proved you couldn't pass with them?

I doubt anyone else has tried....

[M3to335]

I havent proved anything yet. I could be an isolated case or something goofy is going on. Id like to hear what everyone else is doing.

Hell, Id love to hear back from ANYONE running sims who has checked readiness. Id assume without the proper map, no one would be able to get it to pass. Maybe Im wrong. Who knows.

[Blk07335i]

I've got the sims but fortunately here in Jersey new cars don't need to get inspected until 4 years after the delivery date. By then I will have something else so I'm not too worried about it now. Before I put the sims in the performance was degraded along with the limp modes. Since the sims went in no codes and much improved performance. I would like to know if I could pass out of curiosity.

[M3to335]

If you have a decent scanner, give her a scan and see what happens

[f30er]

I'm so glad I never have to get my car smogged....i'm keepin Ohio plates no matter where I go!!

[M3to335]

UPDATE:

My buddy brought by a better reader today. I drove 50+ miles and plugged it in to see what would happen. I plugged it in and it had 2 "pending codes". P0138, P0158.

o2 sensor circuit high volts (bank 1 sensor 2)
o2 sensor circuit high volts (bank 2 sensor 2)

I'm sure you already know this, but it describes pending codes as;

Also referred to as "continuous monitor codes" and "maturing codes". Pending codes occur when the code has not occurred a specific number of times (depending on the vehicle,) causing the code to mature.

I found it REALLY odd that these codes showed up on this new reader. I say that, because I've checked several times over the last 2 months to see if anything showed up on the c-reader and nada. In fact I checked again today on the old c-reader and still nothing.

So, I plugged back in the new reader and cleared those two codes out. Is it possible that these "pending codes" were creating the readiness issue? Isn't it odd as hell that it didn't show that on the C-reader?!

This thing is supposed to be able to check readiness as well. I'll try that later this evening. Wish me luck.

[e90AW335i]

Keep us updated. Hoping it all works out....

how do I check the rediness?? I'd be glad to help out if I can, I have UR catless DPs..

[M3to335]

asdflkjid, most likely you have BMS sims, which muffle the signal. Those shouldnt allow a readiness signal. But, I'd be really interested (just for the heck of it) to see if you do.

What kind of reader do you have? If you go to the manufacturers website you can pull up the manual and see if it allows you to check inspection or maintanence monitors which are a snopshot of your cars emissions system.

It views things such as;
Misfire Monitor
Fuel System Monitor
Comprehensive Components Monitor
Catalyst Monitor (check this one)
Heated Catalyst Monitor
Evaporative System Monitor
Secondary Air System Monitor
Air Cond Ref Monitor
O2 sensor Monitor (check this one)
O2 Heater Monitor
EGR Monitor

It will show either READY or INCOMPLETE (or maybe yours says not-ready).

It is not odd if this is your "C-reader"
http://www.bba-reman.com/content.asp...an_fault_reset

It will not read pending codes or check readiness monitors.
Here is a location that has information about "Readiness Flags" and OBD II Emissions testing.
http://www.obdii.com/articles/OBDII_...s_Testing.html

This may help also....per BMW training:

Also you need to complete a specific drive cycle to "clear" the O2 monitor.
Example of a Drive Cycle for Completing all OBD II Relevant Checks
1. Engine cold start, idling, approximately 3 minutes. Evaluated:
2. Constant driving at 20 to 30 MPH, approximately 4 minutes. Evaluated:
3. Constant driving at 40 to 60 MPH, approximately 15 minutes (sufficient vehicle coast
ing phases included). Evaluated:
4. Engine idling, approximately 5 minutes. Evaluated:
NOTE: The diagnostic sequence illustrated above will be interrupted if:
• Secondary Air System
• Evaporative Leak Detection (LDP Equipped Vehicles)
• Oxygen Sensors - Achieved “Closed Loop” Operation
• Oxygen Sensors - Response Time and Switching Time (Control Frequency)
• Catalytic Converter Efficiency
• Oxygen Sensors - Response Time and Switching Time (Control Frequency)
• Tank-Leak Diagnosis (DM TL Equipped Vehicles after KL 15 is switched OFF)
Vehicle
Speed
Time
• The engine speed exceeds 3000 RPM. • Large fluctuations in the accelerator pedal position.
• The driving speed exceeds 60 MPH.

Within the BMW system the illumination of the Malfunction Indicator Light is performed in accordance with the regulations set forth in CARB mail-out 1968.1 and as demonstrated via the Federal Test Procedure (FTP).

1. A fault code is stored within the ECM upon the first occurrence of a fault in the system
being checked.
2. The "Malfunction Indicator Light” will not be illuminated until the completion of the second
consecutive "customer driving cycle" where the previously faulted system is again
monitored and a fault is still present or a catalyst damaging fault has occurred.
3. If the second drive cycle was not complete and the specific function was not checked
as shown in the example, the ECM counts the third drive cycle as the “next consecutive“
drive cycle. The "Malfunction Indicator Light” is illuminated if the function is checked
and the fault is still present.
4. If there is an intermittent fault present and does not cause a fault to be set through multiple
drive cycles, two complete consecutive drive cycles with the fault present are
required for the "Malfunction Indicator Light” to be illuminated.
5. Once the "Malfunction Indicator Light” is illuminated it will remain illuminated unless the
specific function has been checked without fault through three complete consecutive
drive cycles.
6. The fault code will also be cleared from memory automatically if the specific function is
checked through 40 consecutive drive cycles without the fault being detected or with the
use of either the DIS, MODIC or Scan tool.
NOTE: In order to clear a catalyst damaging fault (see Misfire Detection) from memory, the
condition must be evaluated for 80 consecutive cycles without the fault reoccurring.
With the use of a universal scan tool, connected to the "OBD" DLC an SAE standardized
DTC can be obtained, along with the condition associated with the illumination of the
"Malfunction Indicator Light”. Using the DISplus or MODIC, a fault code and the conditions
associated with its setting can be obtained prior to the illumination of the "Malfunction
Indicator Light”.

Hope this was helpful.

[M3to335]

Yeah, thats the POS reader. Do you think that the pending codes (which has probably been in there since before the SIMs were installed) could cause the lack of readiness?

The emissions guy told me what you were saying below. But Im confused as hell.

Also you need to complete a specific drive cycle to "clear" the O2 monitor.
Example of a Drive Cycle for Completing all OBD II Relevant Checks
1. Engine cold start, idling, approximately 3 minutes. Evaluated:
2. Constant driving at 20 to 30 MPH, approximately 4 minutes. Evaluated:

• The engine speed exceeds 3000 RPM. • Large fluctuations in the accelerator pedal position.
• The driving speed exceeds 60 MPH.

Do I have to drive through step 1-->4 back to back to back during the same trip? The chances of that happening exactly like that are next to impossible.

Also, Im I reading it correctly where it says the diagnostic sequence will be interupted if any of those items in blue occur? I cant over fluctuate the pedal, drive over 3k, drive over 60 etc etc? Please tell me Im reading this wrong

Yeah I have the BMS o2 simms.. I was told that these would pass emissions, I don't currently own a reader but I took it to autozone after I installed them and they didnt find any codes..
