VCDS Readiness for Inspection, NY

[lswing]

So here's a screenshot. I've got a current SAI leak that pops up and I clear the CEL. From my reading, this reset/clearing faults is causing some of these to show as failed until I drive X amount of miles. Also, I get this failed communication box after 5-10 seconds. Looks like NY state is lenient on some things, even giving a one year exemption if needed. I'll check with the shop about fixing the SAI if they can get to it, or maybe just looping the line to trick the computer as commonly discussed, the last shop left something loose but it all works otherwise. Thoughts on this before I visit the shop? Thanks! No other codes when scanning besides my SAI leak caused by some previous repairs.

I had that SAI issue about 5 years ago, ended up replacing the 1/4 rubber tubing for that side of the system and that was the fix. There are two valves toward the back of the engine and the tubing can get pulled off (torn) when the air box is taken off. I had that pleasure after a service visit at Audi. Easy to fix.


Resetting system to "Readiness" for inspection takes a varied speed and distance thing and you can find the specifics on line. You drive so far for so many miles per hour then increase speed, etc. It's more than just driving for 10 minutes on the highway. LOL

In PA, I'm allowed 1 failure as long as there is no CEL.

I'm pretty sure that incompletes are ok, too.

There's some discussion of this issue in my recent thread about removing and coding out SAI. You can use the VCDS to set the readiness bits, outlined somewhat here:

You can use the VCDS to set the readiness bits

Does that mean you can manually set the readiness indicators from incomplete to ready in order to pass an emissions test? Assuming there isn't something that will immediately set a CEL after a reset. That seems too easy.

You can set readiness with VCDS google how to do it

So even if the car has for example, evap emissions leaks, a weak cat, misfires, etc. that turn the CEL on after a few miles, you can drive to the inspection station and in the parking lot, erase the codes and set readiness so it will pass? COOL. This works on any Audi VW with OBD2?

No. Ross-Tech has certain 'routines' for some engines/platforms to get the readiness set that is an approximate equivalent of driving the car the the needed time and distance to complete readiness.

I'm pretty sure that the C5 4.2 cars are not in their library.

Don't be misled by this. It's not a way to artificially set readiness on items that can't be made ready. If your components are bad or missing, then they will never be ready. It's just a way to set readiness without driving a lot of miles.

I posted a scan at http://www.rs6.com/showthread.php/32313-FS-2003-RS6-needs-trans-work-plus-a-2010-VW-GTI-for-one-price in thread #3 which shows 3 engine and 2 transmission codes along with the MIL on, yet Readiness is all 0's meaning it would pass. How is that possible?

because the codes don't have to do with the different systems needing to be in readiness for an emissions check.

The 8 digits are:
Exhaust Gas Recirculation
Oxygen Sensor Heating
Oxygen Sensor
Air Conditioning

Secondary Air Injection
Evaporative Emissions
Catalyst Heating
Catalytic Converter(s)

The codes you posted had to do with:

3 Engine:
Exhaust Gas Temperature Sensor
Vehicle Speed Sensor
MIL Request Signal

2 Transmission:
Gear 3 Incorrect Ratio (Intermittent)
Gear Ratio Monitoring set MIL

OK. Good to know it would pass emissions if needed.

It's possible to pass emissions and fail the safety and functional inspection.

My inspector would most likely not even perform an OBD emissions check if the MIL is on. Normally, you need to pass the other safety/functional related tests before they do the emissions check.

Yep, read that through, just looking for some confirmation. Thanks, I'll give the readiness settings a run through to save the driving around and see if it works out, will report. Basically I just need to fix the SAI leak, maybe in a few weeks, and stop clearing codes. In the meantime I need to pass inspection to register the car in NY.

I'll try and confirm, thanks.

I've done it on my RS6 but like Steve says it only approximates the driving cycle and speeds things up. It does not allow you to reset something that does not exist or is bad

Got it. So even thought I clear the code for the SAI, seems like ECU still knows it's bad on startup, and that will remain. The clearing of the CEL is triggering these other readiness items to trigger as reset also, so I will just update them for now...need to get the SAI hoses fixed anyhow.

Just by driving you mean, does not appear to work with VCDS using computer only.

I think this is the case, does not seem to work following Ross-Tech instructions, unless I missed something.

Any more info from anyone?

[lswing]

Never mind, SAI leaking hose fixed by the shop it appears. Time to drive a few hundred miles and get the readiness parameters reset.
