You need to ask at your local station.

Here, it says for cars through 2000, we are allowed TWO unset monitors, and for 2001+ cars, only ONE unset monitor. However, the catalyst monitor cannot be one of the unset ones.

BUT... even though they never actually told us this, I've found out that the diesels, no matter what year, cannot have ANY unset monitors. Which has become a nuisance sometimes, as I have had to drive some cars, more often 2009+ TDIs, quite a bit. I often have to drive them home overnight to make sure they get a good run out the highway, and in some cases I have had to do this twice.

I'm sorry that I can't be helpful. All I can say is that readiness is the devil. On some cars its worse than others. 1000 miles should have been enough, but if you read up on what driving sequences it takes to reset certain monitors of certain vehicles it is totally insane.

Yes, you are right. It's as if I need to rent out the Bonneville Salt Flats to do this driving cycle. Part of the cycle instructs the driver to decelerate from 55-20, on top gear. For a manual car, the engine's ultimately going to die. Worse, the last part of the driving cycle instructs the driver to decel from 55-0; yes, I will get onto the MassPike and go 55, get honked at, and then just slow to 0 on the shoulder, no sweat.

Is this driving cycle supposed to be completely followed in order?

Would ambient temperature have an effect on readiness as well?

As I have said in the past hook up the Vag Com and do a DPF drive reset. This will force most of the EGR readiness tests and most of the MA emissions readiness that are tested.

Unfortunately, I am one without Vag Com. I have (so far) not needed to use it, as most of the CELs were able to be found and resolved from searching this forum.

Dr Volks, I see you are south of Quincy. Maybe one day I might have to take a trip to your shop and request your assistance on this. Thing is, I have had the car go through TWO DPF regenerations already, so it doesn't make sense why the monitors still aren't ready.
