Aarrrrgggg..... My bone stock 2006 CRD failed emissions. No check engine light or anything. Tester said I failed the Opacity test. At 60 MPH it was 58%. Needs to be below 35% Thing only has 90K miles. I believe I have the up to date computer firmware.

Any thoughts of where I should start looking? EGR? computer? Grrr....

Any suggestions on where to take it for service in the Broomfield/Boulder area?

You don't often hear Boulder residents complaining about failing inspections. The inspector did know it was a diesel right? In UT dealerships can do inspections so I just brought mine there. I figured if it failed, they'd know how to make it pass. Don't know if this applies to CO though... I didn't know CO had inspections... learned soemthing new today.

Yes, Colorado has Emissions testing along the Front Range (Denver, Boulder, Fort Collins, etc). We have our fair share of Brown Cloud during the winter. Colorado Government did not want to be another CA, so they started it back in 70s.

Looks like I'm headed to the Boulder Jeep Dealer to get it sorted out. Soooo Sad... Still love the Jeep!

58% is pretty disgusting. There would be a black cloud coming from behind the vehicle. Sounds like you have an underboost problem, either from the turbo itself not actuating or a boost leak through the EGR valve, or from the intercooler or hoses. Do you notice it being down on power?

I did not see much drop in power. It is my daughter's first car. Another piece to the puzzle. After the emissions test, when they pulled the jeep out, you could tell the brakes were hot and had the burned smell of overheated brakes on a long down hill. He tried to turn off the ESP but might not have gotten it off. If the brakes were applied to try and compensate for the front wheels not turning on the machine, maybe I had 10x load that was expected.

I'm having Pollard Jeep look into the ESP functionality. When I push the ESP button on the steering column, I don't see any light turn on the dash. Wondering if this is the real problem and I also need new brakes on the rear :cry:

That's a definite problem if the ESP was holding the engine back.

Maybe they were measuring the opacity of your brake pad smoke. :lol: I hope everything turns out ok.

You need to check and get your CRD off the rollers! When the forced mine to do it, it lit up the ABS light and the engine shut off. Mine is a 2005. The CPU thinks you are in a skid and shuts down.

The Cadilliac Northstar, Many BMW's, Corvette's, etc. all have traction control and DO NOT go on the rollers. The CRD should also be on that list.

This sounds correct with the brakes trying to stop the skid, making the engine work harder and thus making lots of black smoke.

I would go fire someone up right now about it.

Darn, that sucks, in NY we do not even need to connect the OBDII to the tester for inspection, only gassers? Can you just take it to the Jeep dealer and let them do the emissions test?

Dealerships don't do emissions here. gasoline vehicle go through the state emissions program at air car colorado testing stations, diesel go through a similar test at privately owned stations.

No emission testing needed here in the Springs :goink: .

Well, life just got a bit more interesting. Turns out I might need a $700 light bulb. Well, the plot thickened. Took it to the dealer. They discovered I had several idiot lights out. ABS, ESP and also the check engine light were out. Offered to replace the bulb. Figured that made sense. The pulled out the instrument cluster only to discover there are no bulbs to replace. To fix it -- I have to replace the $700 Instrument cluster -- 10 days to get the cluster in.

We "believe" the ESP button works. Just no light turns on. I think the emissions tester did not have ESP off which explains the smell of burnt brake. I think the added load to the test help me fail. They can't find any thing else wrong with the Jeep. Uggg... Good thing I love diesels!! Will keep you posted!! $145 to educate the dealer that check engine and ESP lights are not bulbs that can be replaced.

You could have sourced a used cluster and installed that, would have been a heck of a lot cheaper.

I just passed emissions with a stock '05 in Denver this August. I believe my opacity was 2%. I did have the aforementioned problem with the ABS and ESP lights from the rollers, however. A five minute power down fixed it for me, but I'm definitely not going back to an emissions joint that tests on rollers in 2012 if I can find an alternative. If I can help with anything or you have/need suggestions for non-dealer options in your general neck of the woods shoot me a PM.

ESP vehicles often need to be "dyno'ed" or "emission rollered" in 4WD, find a dyno shop that also does emissions

this is one of the reasons why that particular emissions testing method has NOT been adopted to many emissions testing states, the original adopters were short sighted in terms of the future of vehicle safety equiptment

on vehicles that have difficulty having the ESP fully disabled in terms of being dyno'ed, the answer is a 4 wheel dyno and nothing else

hope this is beneficial, just thought I'd throw it in there, last time i went to dyno i ended up sittin there talking to about five guys with 4wd and ESP about the issue

I'd expect those emission machines will either go away, or be entirely adapted to 4 wheel roller

That makes sense, the load was giving the CRD a good work out. I would not take it back to that place that smoked the brakes, you should even document this in case you have problems down the road, you might want them to compensate you?

I am even more thankful that Pennsylvania has no emmision testing for Diesel powered vehicles. they don't even hook up to the computer or anything. I'm not even sure if they look for a CEL. I still has to pass the anual safety inspection where they check the brakes, tires, lights, mirrors, suspension and exaust systems.

Now if it was gas powered they do have to pass emissons. Pre 1996 has to pass visual inspection of emmissions parts and gas cap test. 1996 and newer have the same plus are connected to OBDII computer diagnostics machine.

I'm not convinced that the cluster lights are your real problem. The cluster has ca. 9 replaceable illumination bulbs that work in conjunction with the headlights and a number of LEDs that illuminate the various message or warning indicators in the panel. I would be more than extremely surprised at multiple LED BULB failures as these bulbs generallly are good forever hence you might want to look for causes other than just multiple bad bulbs. The system does run a bulb test at start up that should light all those LEDs for about 3 seconds, does that work? If not what bulbs work vs. do not and what do the failed bulbs have in common? For example on stoutdog's 1993 Dodge an apparent circuit board bulb problem was actually traced to a loose plug in to the board connection. Alternatively you might have a common ground problem but I don't really "do" electrics all that well. I also note that the service manual while it says LED bulb failures are "serviced" by replacing the whole EMIC the manual also says the bulbs are soldered to the panel which makes me wonder if a decent electrical supply store might have replacement bulbs that a good hand with a soldering gun could do a replacement for any bulbs that are really dead.

FYI there is another thread on the forum about problems with roller testing these vehicles in Arizona that you might want to check out.

After reading papaindigo post I wonder if they use SMD Led to light CEL indicator in the panel, they "suppose" to last forever but they don't survive very long if you apply higher voltage, you need somekind of voltage regulator control. In this case we got individual signal apply to every indicator so we need to drop voltage from 12V to arround 1.5V (I estimate)
If you got lots of burn signal indicator in your instrument cluster you probably got a problem in the voltage regulation circuit too so just replacing the SMD led will not resolve the problem...need to see before what we dealing with! Make me regret my old 75 GMC pickup bulb wire instrument cluster design....So much space to change bulb :mrgreen:

We got no emission control up here so I'm "Out of my league" and realy watching this post to learn in case those mesure apply to us soon..

To bad in CO there are only certain places that you can get a diesel emission tested.

If you have a AWD vehicle or a vehicle that comes from the factory with 34" or larger tires(H2 and Ford Raptor) you never will have to do the test,they just pass you as they can not put 34"+ tires or a AWD vehicle on the dyno.

scooter,

I am also in the Denver metro emission testing area and all of my other vehicles have gone thru the process. For those not familiar, the Denver testing is enforced at vehicle registration renewal and specified intervals and is not required every year.

While the language in the emission testing program is rather vague pertaining to diesels, I read it to require testing. However, my 05 CRD has "emission exempt vehicle" sticker on the windshield that was there when I bought it new. I completed my 5th year vehicle registration renewal in March 2010 without a testing requirement. Thus, I appear to be completely out of the program.

Did you assume you had to pass testing, or did you get a testing notice with you registration renewal?
