Anyone else have issues with emissions test station computers not communicating with your car via the OBDII connector? I, and my mechanic can read my E38 just fine but the emission station's computer fails to connect.

Yes, I've tried multiple emission stations.

Yup! Me. E46 M3 2001.

They had to dyno it instead of the OBD.

have your mechanic check bmw for software updates. bmw has had to update some versions of its software to talk to generic emissions stations.

Look into recall campaign no. 06E-A03, BMW Voluntary Emissions Recall Campaign to Reprogram DME for OBD Communication.

Affected cars- 2000 to 2004 M Roadster/coupe, M3 Coupe/Convertible, Z8, and M5

Hmm... very strange - now that you mention it - the only difference between my Emissions inspection this vs. the last time was that I actually DID get the 06E-A03 recall performed on the machine.

So it DID work BEFORE the recall was performed and DID NOT work AFTER the recall...

Very Strange!

I had a discussion with the State today and the answer seems to be that some computers take a long time to fully reset so the VA system will communicate with them. The answer they gave me was basically "drive it for a while, then take it in and see if it passes, if it fails, drive it some more":mad:

No one can say how long it takes, or if there's any way to test the communications other than go to an emissions station, pay $28 and hook it up.:mad::mad::mad:
There are no longer any provisions for an alternative tailpipe test.:mad::mad::mad::mad:

What a crappy system:icon_evil

That sucks! Boy did I get lucky!

I guess you should probably take it into a dealer and make sure they take care of it one way or the other.

Is your car still covered by the emissions warranty from BMW?
No BMW is crappy not the emission inspection.

What you may want to do is disconnect the negative terminal of your battery overnight then reconnect and see if maybe this resets everything.

The following doc shows the OBDII driving profile. It should be applicable for your car.

No, the funny thing is the car was purchased by someone in North Carolina in late August and passed North Carolina emissions (through the OBDII) just fine. I bought the car earlier this month, and it won't communicate with the VA computer. My Indy's system can read it just fine, just not the State machine.:confused:

Emissions warranty is tranferrable and runs 8years and 80k miles. Dont remember for sure.

I tried to find out if the law changed between 10/1 and this month - and I couldn't come up with anything.

Sorry to be referring to Google cache rather than the actual DEQ site ( its broken!)

I got mine done at Elden Street Service Center I THINK. Not exactly sure its the one right next to the Shell. And they did it for me without the OBD communication.

ALSO At the risk of being sued for defamation - what I have here is just pure speculation - I have been told that apparently the Shell guy just passes cars as is - and has had to shutdown and restart multiple times.

I can give you more details on the location if you are interested.

I am sure you already have - but do try other inspection stations to see if they will do it without OBD.

Again disconnect negative battery cable and let it sit over night. Hopefully you have the radio and any alarm codes. Reattach cable and drive for few days and try test again

I don't know what OBD stand for in your message & subsequent replies. However, I have owned a 1998 540 since 2002 & my wife has a 2003 330 and we have never had a problem with emmission inspections. I take both cars to Pinecest Shell (formerly Texaco) in Alexandria. They are close to the Intersection of Braddock Rd. & Rt. 236 (Little River Turnpike). Their phone number is 703-750-2991. You might give them a try if you haven't already found another garage.

A service station or dealer performing the emission test years ago could cheat on the test. Now its a little more difficult since the results on sned directly to the DMV.

The guy I knew who would pass any car for a case left where I get my car inspected in Alexandria. I still go there because no one knows about them and there is maybe on car ahead me in line at noon on the last day of the month.

You might want to try another forum where some techs hang out for advice.

Still no luck:icon_conf. Fuses are good, Autologic and Peake tools communicate just fine. It just won't talk to the State machine.

Guess it's time to take it to the dealer.:wallet:

Seriously disconnect the negative terminal of the battery and let it sit for a few hours. Reconnect drive for 2 days and see if you still have the same problem. Nothing to lose as long as you have the radio code.

Yes, I've tried multiple emission stations.

Yes, I have a Z3 that has been at the dealership for 2 weeks trying to resolve this same issue. I will let you know how it turns out.

I have an 04 530i and I'm having the same issues, when I try to do the emissions the VA system says that the O2 and exhaust diagnostic monitor is not ready yet.I have driven the car for close to 150 miles but no luck yet!!

I took mine into the dealer and they had no trouble reading it through the OBDII port. Of course they showed no faults or errors. They did a complete reprogram of the DME and added several SW updates. Now I just need to run 3 drive cycles and put a couple of hundred miles on it.

I took mine to the Herndon auto care and my car passed the emissions with no problems. I tried doing it at the Shell gas station which is right in front of it but they couldn't do it for the past week and finally I got it done at Herndon Auto Care.

Finally got the problem figured out - It's the Virginia DEQ analyzer's fault!:eek:

There are two types of analyzers in use in Northern Virginia, The ESP unit and the SPX unit. The ESP unit has several software issues trying to communicate with higher end cars. Specifically, if you have an M3 or M5, Z3, Z8, or E38 750, or if you have had the recall campaign no. 06E-A03, BMW Voluntary Emissions Recall Campaign to Reprogram DME for OBD Communication done on your vehicle you need to be sure and use a test station that uses an SPX analyzer.

Ask before you let them hook you up!
