Regarding the "Readiness" stuff ...

http://www.e90post.com/forums/showthread.php?t=603569

Is this nonsense really necessary?!?! You have to follow this specific drive cycle pattern to even get the vehicle to attempt to trigger the OBD "readiness" tests?

I'm certain I haven't done this specific driving pattern since the latest remap came back. I'm not even sure how to duplicate this exact driving pattern in a safe manner on the roads around here.

I learned something new today. Here in PA diesel autos are exempt from emissions testing. We are only required to do the annual safety check. (brakes, tires, horn, lights, etc)

So from my understanding, for Pennsylvania, I can still pass state inspection even with the check engine light on.

However, the readiness monitors are indeed what PA uses to enforce emissions testing for the gassers. It wouldn't suprise me if this changes for diesels as their volumes increase.

Amigos I came a DPF manufactured in france I will post pics tomorrow

This thread has a bunch of useful info regarding bmw specifics to setting the obd "readiness". Sounds like a lot of fussing around with some people in certain locations having difficult times finding places to drive where they can duplicate the needed "cycles"...

As an aside, i wonder which other states also only have safety inspection for diesels. Mark tells us PA. I also offer my home state TX. I thought i recalled TDI saying Iowa also wasn't emission testing diesels.
Running list, PA, TX, IA

+GA, no inspection for diesel

No emission inspection of gas or diesel vehicles in Iowa ...

Here is a breakdown of the requirements in California:

For "Smog Counties" (Basically counties that are in/near major population centers- SF/LA/Sac/etc.):

• Bi-annual inspections are required.
• Diesel power engine passenger cars and trucks do NOT qualify for the 4-year new-car SMOG check exemption program that gasoline vehicles have.
• The inspection process does not utilize a dynamometer (rolling road) test. A simple snap-throttle test is used. Excess smoke will cause a fail of the test.
• Currently no OBD readiness checks are performed. (I suspect this will change in the future just like the diesel exemption a few years back.)
• Currently the technician looks for a check-engine light only.

For all other CA counties void of human life:

• No bi-annual inspection required.
• Only inspection required upon transfer of ownership.
• Inspection process is as above.

My experience has shown that the technicians are very lazy on the visual inspection. I think that any mods made that don't cause a check engine light and don't look obvious- you'll be fine. However, when CA changes the OBD readiness check requirement, we will be SOL.

Readiness is required for diesels in NY. BMW wasn't able to inspect my car (335d) due to certain monitors still not is ready mode, after they reflashed the DDE. It needed to go thru the drive cycles.

My take on this drive cycles: just driving the car around 2-3 days will set everything in ready mode. It is not necessary to follow the drive cycle procedure as published by BMW. I learned this the hard way on my 135i.

[135i_vs_]

To add a little more on the readiness, it prevents someone from fooling the inspection process by resetting the check engine light a block away before getting the car inspected.

I need to register my car in a different state. Got some friends in Wy and Fl.

Interesting. I've been reading of lots of people who have a different experience than yours. Many of them having to make special attempts to duplicate the specifics of that published cycle so they can pass their inspections.

Although it does appear some owners report not having to do the cycles in the specific order, or even during the same drive cycle. I can say that I purposely avoid doing the first and last segments of that test as its a waste of resources and time, so some of those items would never trigger a readiness state. And my normal driving routine would also not trigger the middle two segments either.

I may try to do a purposeful 2 rounds of the specific test cycles to see what happens with the readiness situation.

I found this link for CA counties. Apparently San Bernardino and Riverside are not listed. Got relatives there

There goes my DPF

Whe are OFF topic amigos open another trhead on this issue ok.

[TDIwyse]

I was thinking the issues of potentially failing emission inspection would be relevant to a "DPF Delete" thread? And the EGR stuff was all related to the DPF modifications ... But I'll stop updating if its not of interest to those reading this thread.

[Puerto Rican 335d]

Thanks for info TDi but the thread has gone from DPF delete to emissions loop holes and we need to stick to this DPF send me a txt at 787.459.4518 so you can post for me some pics I got from ebay since Im at work, a DPF made by GT Performance of france ok

[Puerto Rican 335d]

TDi this what I got out of Facebook

https://www.facebook.com/pages/Perfo...64991100275848

I kept scrolling down in face book and came up with their website

While this may have gotten off topic from a dpf delete, I am very interested to see TDIs regular updates and data logs for his EGR 'mods'. I hope to see more updates either here or in a different thread as I'm sure many of us have interest. Thanks!

[crazyinp]

TDI please keep posting updates. For most of us DPF Delete is only an option if we can pass emissions. Both of those are related.

[dixy2k]

It's all related to the restricted emissions which messes up the ride.
EGR delete, DPF delete, every little bit of info helps.

Emissions tests are also related to the DPF delete as for some people it may offer advance knowledge to pull the trigger or not.

+1.

No one is doing DPF delete and/or EGR delete without coding.
I don't think anyone wants a coded DDE that won't pass annual inspection (safety and emissions).

Let us know if you get all the monitors in ready mode. Also, you can mention this to the tuner (Ecotune), they should know about this.

Just to finish up this loose end... The EGR cooler is completely gone now. Pic shows things just after replacing connection (lost a little more coolant). Road tested for leaks and checked coolant behavior. Everything looks good. ~5 pounds off the front of the car.
