Just a small warning....not long ago I had the recently released software update addressing the "bucking" issue with some diesels installed.Today I took it in for its annual state inspection and when I returned I saw that it sported a rejection sticker.Astounded,I asked the guy how that could be and he said that somebody must have disconnected the battery because the state's computer couldn't get enough data from the car's computer to allow a pass (for the emissions system).He said that the car's computer needs time to recompile enough data for the inspection computer to read.

So it appears that any time the dealer flashes the car's computer it's wise to wait a while before undergoing any kind of state emissions inspection.

 

That's a **** poor reason for failing inspection.

MD would have done a secondary test and passed you.

 

Connecticut???

I live in CT and did emissions tests on two cars last fall (pre-MB). AFAIK it was just a stuff the sensor in the tailpipe test.

 

No emissions tests for diesels in PA.

 

Most states have gone to the OBDII test with a fallback to the sensor in the tailpipe - which they should have done here.

 

Lots of places don't even have equipment to do the tail pipe test any more as the OBD II is so simple to do.

It just is that it should not take that long for the sensors to reset. What takes most time is to get catalytic converter sensors reset again and that usually takes just one road trip to drive. It can take a couple of days for it if not driven a long stint on a highway.

 

These tests are rubbish and I don't think new cars need them . Do you really think that global warming is happening just because of burning oils
These cars meet Euro 5 Norms that are very intense

 

wow! how lame.....I thought you were going to say 'because of side markers' or something! can't believe it!

good luck homey

 

How much info. does the computer need? Days? Weeks? How long did they give you to get it right and be retested?
Another reason to like living in the Boonies on the Upper East side of Texas. No sniff test and no lame extra charges for a sniff test. Got to love living way back in the woods.

South Carolina does not require any kind of safety, emissions or other testing. One reason why so many vehicles have one or no head or tail lights, defective or disconnected mufflers, etc.

 

Northern Virginia requires emissions testing on diesels. I just missed it as I recently moved to Central VA in which no emissions testing is required.
Back to this thread, I thought that I read a posts that a person was having trouble with his OBD II port not connecting with a scanner tool. I think he had to replace the OBD II connector.

I had the same problem last year with my BMW. It's not really a new issue, it happens when the battery is disconnected for a period of time. Normally driving it for 40-50 miles or so is enough to reset the system.

I don't know what it is for your state, but Texas lets you re-test within a week at no additional charge. I drove the car around for the rest of the day, brought it back in the morning, and it passed.

 

+ 1 for New Jersey

 

Absolutely correct! These tests are nothing more than a disguised tax. Exception was the state of Georgia. They exempted new cars. I think for three years if I remember correctly. Not so in NC. Inspecting the emissions of a brand new car manufactured to the latest emission standards is nothing more than an excuse for a tax.

 

Un-possible. OBDII was introduced in 1994 and mandated in 1996. If they only did OBDII then it would mean that they cannot test cars prior to 1996. They can do away with the sniffer in ten years when the 1996s have reached "antique car" status and are exempt from testing.

 

Many (most?) states exempt new cars for the first two or three years.

In MD it is unlikely that the state makes a huge profit on the $14 they charge for a test every two years. Each testing station costs quite a bit of money. Each test takes about 10 minutes so figure each inspector does 5 tests an hour (it takes time to pull in cars, retest etc.) so they pull in about $70 per inspector - hardly enough to pay salary - much less overhead. Even at 6 tests an hour, they are making a whopping $84 an hour.

 

In NC new cars are not exempt. The test is not carried out by state run facilities. The private inspector keeps a portion for their labor to carry out the ten minute inspection. The rest goes to the state. I will not accept that revene going to the state for this purpose is not a tax. A brand new car, meeting all emissions standards is subject to this state inspection. This is nothing other than a tax. Just because it is a small amount of revene does not make it any something other than a tax.

 

Additional information,

According to the state of NC $6.25 of the $30 paid every year is a tax. Oh, and if your windows are tinted the inspection costs an extra 10 bucks. Let's see, $6.25 times 8.5 million vehicles every year, less the 2 million that may be exempt and overlooking the tint tax, about 40 million a year. I agree, not a huge sum of money as far as revenue streams are concerned, but it is clearly a tax. I do not believe that in increases safety or improves air quality.

 

The only way to determine that is to see statistics on how many new cars fail inspection. If that number is non-existent or very small, then you can petition your state legislature to do away with the test for new cars.

 

That is probably correct. My only point is that in our state, it is nothing more than a tax under the guise of public safety and clean air. If new cars were exempt as in many other states I would buy the clean air and safety rational.

 

In MD i think he would be exempt as it's a diesel correct?

 

Correct.
