Emissions
2010 Volkswagen Jetta TDI 2.0L (CJAA) 6-spd (02E)—3VWPL7AJ9AM687514
Emissions Test Required Monitors Not Set

No recent repairs. 46,000 miles. No Monitors run after 14,000 miles since VW dealer reflash (except continous). This car needed to pass emissions test to get tags. After several hours researching Alldata, VW, the evil network, online forums, I could not find a concise plain English drive cycle. BTW This vehicle does not support shop bay monitor reset. I gather that no VW/Audi diesels support that function. I took the VW document and made it into plain English (the best I could), & here it is. I have driven it 95 miles on the dyno so far. I have not repaired anything. Now I have 2 not complete so I smogged it and on to the next car. I did perform a standing regen at 1 point.

And the last step is 45 minutes? Really?

DYNO? I'm new to this forum, but i was curious if this was one of the affected "recalled" scandal tdis.... please read this as this segment just JUMPED Out at me... "Volkswagen has admitted that it equipped the control software for its 2.0-liter TDI diesel vehicles with a "defeat device" that detected when the car was undergoing emissions testing and significantly changed the operations of its…

The TFM's have a special procedure that that they use to run the diesels. Your procedure looks about right, except the dyno. You will need to see all 4 wheel speed sensors register near the same speed.

Yes this is an affected "clean diesel". It has had the update/reflash from VWOA. That was their fix for the defeat .

Sounds like the fix didn't take.

If it doesn't test,it doesn't fail.

Don't forget about the steering angle sensor movement.

Mark, One of the issues with the Dieselgate was the SAS does not move when on the dyno. So, if you are on the dyno you are running an emission test not running monitors/driving the vehicle. I was never told if this was taken out of the new software for running the monitors, but the TFM - field engineers, always talked about the driving of the vehicles had to be precise. I am looking for the…

As i understand from reading the above the car must be driven. Unless the chassis dyno drives all the wheels and you input some steering it may not run the monitors. But why didn't it run in 14K miles? Makes no sense. I'll go back an re-read the OP. Which monitors are incomplete?

Not sure if this has been resolved but here is a procedure to set readiness. static​.​nhtsa​.​gov/odi/tsbs/2015…​.​pdf does state that a regen has to be imported once per drive cycle and can be enabled through scan tool

That link is about a coolant leak? I referenced VW Audi TSB material to attempt to describe a drive cycle.

Hi Bob, My Bad for the late response. What I got was a Porsche doc in which I was told worked across the VW/Audi/Porsche line. I have enclosed a picture of the first page. Thank you for the validation of the drive cycle procedure.

Hi Steve, I had not seen the Porsche version, but I assume that the procedure/cycle is the same as Audi (V6 is an Audi engine) listed above. I like the highlighted stuff, very amusing to those of us who were/are fated to set readiness all the time. I had a specific "track" set up in my rural area of Michigan that I could run the cycle without interruption and set all readiness ~95% of the time…
