The value works based on mileage at the time of turn in, not mileage at the time of filing the paperwork, by the way.

So it seems like it is better to delay until shortly before the required "smog" test.
You'll never fail a test without the fix. It's designed to cheat the test.

And you'll get a sticker with reduced emission requirements if you do get the fix.

Lastly, any state that accepts the settlement can NOT deny you registration because of the diesel issue, fix or not.

others have had the DPF crack and leak soot which clogs up the egr and throws codes at 60k or so.
We do know for sure, they crack because they are oval, not round, so they expand differently between the long side and short side. Run it through enough heat cycles and it will crack. Based on what I've seen, I'd estimate the number of TDI DPFs that have made it to 250k to be in the hundreds, while the number of those that have cracked before 200k to be way into the 10's of thousands. All the really low failures I've seen (<50k) have been cars with aftermarket intakes. Throws off the MAF signal and a cracked DPF is the result.

For years I have this suspicion that intercooler moisture might contribute to gradual DPF weakening. You have this lump of water ingested into the engine under hard throttle application, forces through the hot DPF and expel out of the exhaust pipe as huge cloud of steam. Imagine spraying hot water over high temperature ceramics and now repeat this process hundreds of times over the life of the DPF....

Thanks,

That makes sense.

Is there a deadline to get the "fix"? I'd like to wait as long as possible.

Also, what if I don't get the fix? Will I be unable to register/smog my car in the future? I assume I won't get the $5,100 without the fix.

The last day you can register to get the fix under the settlement is 9/1/18, and VW has to perform the modification before 1/1/2019.

You will not fail the smog test if you never get the fix. And yes, you would not collect any money unless you accepted the modification or buyback.

My concern is if a part fails, on my unfixed TDI, that would've been upgraded with the fix, specifically the NOX cat. Even though they don't seem to be a common failure in the CR TDI, that is my concern.

Since there is not a new DPF included with the fix, I'm assuming those parts will be available in the future, and be the same for a fix or unfixed TDI?

VW has issued disclaimers about parts availability in the event that you keep the car and don't get the fix done, but it presumably pertains only to components directly involved in the fix. For example, the original (non-compliant) LNT (NOx catalyst) will be discontinued, as will the original ECU with the original (non-compliant) programming. (The ECU hardware will remain the same, but the software programmed onto it will not be.)

I don't recall ANYone ever having issues with the NOx catalyst on these cars, so it is probably a non-issue in the real world. And even if it does fail, the consequence will be that you are obliged to get the fix installed on the car. Bear in mind that if you wait until after the deadlines listed above, VW will no longer be obligated to pay you anything, even if they have to install the fix hardware and software in order to keep you on the road.

The only thing that I can foresee with the ECU if you don't get the fix done, is that let's suppose a couple years down the road there's some sort of issue that turns up which requires the ECU to be reflashed. The original non-fix software will no longer be supported, so at that time, in order to fix whatever the issue is, they'll be obligated to install the fix hardware and software, and since you neglected until after the program end date, they're not obligated to pay you anything.

Just get it done if you want to keep the car ... That's the whole intent of the way it's set up ... It's not VW's fault if you procrastinate; this is another lever to encourage you to get the fix installed if you want to keep the car.

Quick question.
I have a 2009 jetta tdi that is stock other than the adding the kits from 2micron, the "Contain Flow filter and the Pureflow kit."
Since this modification is in fuel system do you believe I will need to have those removed for "Emission Recall " or don't worry about it since it doesn't involve the emission system.

It shouldn't be a problem in theory, but personally I would remove anything that isn't stock in order to remove any possible excuses.

If the warranty is the same as Gen3 car. The DPF is covered. If your DPF is cracked they should replace it.

Now if they make you pay for the DPF. It is a wash after the settlement money. And now you use loose MPG after the fix and smaller pay back.

Sounds like I will fix my cracked DPF and keep my mileage increase and power from my RC1.

Well dang, I was hoping for a new DPF not just the LNT on my 2011.

Anyone still waiting for the portal to allow for scheduling of your fix?

Schedule Your Appointment

The next step in the process is to schedule your appointment to complete the Approved Emissions Modification. An Emissions Modification for your vehicle is not yet approved by EPA/CARB. Volkswagen will contact you when there is an update on the status of the Emissions Modification for your vehicle.
Been showing it still till 8/14/17

I just finished my paperwork yesterday. I was waiting on the fix announcement to make the final decision between buyback and fix. I'm opting for the fix and the $5000 in my pocket.

See my post, #12 here. I asked about existing problems when I scheduled my appointment.
