Phase 1 of the "fix" is a software reflash only. DPF and CAT replacement are part of Phase 2.

Wow, glad I signed in and read this thread today. I was seriously thinking about buying an 09 sportwagen for sale here in Denver. I test drove the car a month ago, it had a CEL, I pulled the code - I don't remember now what the code was, but I read through these pages and thought it seemed like the dpf. The car is still for sale... really cheap... so I keep thinking maybe I should go buy it... now I'm thinking that's a really bad idea. http://www.thesharpestrides.com/vehi...lkswagen-Jetta

That car came up in my searches as well. I couldn't get past the well worn interior. The price has dropped a lot since I was looking just a month ago!

Is there an easy way to tell what phase has been completed? I'll start a new thread for my new car, but have some questions.

Sorry, I screwed up in my original post. OP has 2009 so the replacement DPF is setting that DTC.

2009 gets a new DPF because NOX cat has to be cut off to be replaced. 2010 up to 2014 the NOX cat unbolts to be replaced so does NOT get a DPF.

2015 have new engine and Phase 1 get flash only, Phase 2 is parts replacement.

Oilhammer, is it safe to assume you are equally comfortable working on Merc BlueTecs? I have a 2014 GLK that won't be in warranty for much longer. I have a trusted shop here for stuff like brakes and oil changes, but anything more important (like DPF) I'd like to have a real Pro take care of when needed.

I won't consider myself an MB expert by any stretch, but I am not afraid of them and do my best. Learning more all the time, especially since I bought a Sprinter last year.

Default Still happening.

on 3/6/18 the dealer found the wrong gaskets were used by the technician during the modification. We all thought replacement would solve the problem. I'd noticed regens happening shortly thereafter and all was well. I've been driving the car "as recommended" on some longer trips (50+ miles) and two days ago I was driving to hike in a state park when the CEL came back on! It's only been 550 miles on the odometer. I've noticed the CEL has come on when I do a hard acceleration, like when passing or accelerate on a steep hill.

So, it's no longer my driving habits.

I dug a little more into the cars we have come in with codes like that. More often than not there is an air leak or vacuum hose connection that is causing a marginal condition. ANYTHING that screws up the ECM's control over air flow will cause DPF regen problems.

I'm hoping Jason is on the mark, but unfortunately, undoing the build-up of gunk caused from not running the car for long periods is going to take some time. And in actuality, not completely possible without tearing down the engine and cleaning it all out. But driving it for longer periods of time and perhaps some proven additives to both fuel and oil might help the process.

German tune-ups, although not as popular as the version from the Italians, is still a good way to keep things cleaned up on the interior of a healthy motor.

Thanks Jason, that's something to consider. All the tests that the VW tech line advised the dealership to do today came out perfectly fine (as they have each time). My case has been elevated to a "level 2" and a field technician will be coming to St. Louis on Tuesday 5/1 to review the case and test my car. They're performing a regen today so I can drive the car over the weekend.

I assume that regens can be triggered with VCDS (if necessary) to avoid trips to the dealer....yes?

Another problem is the ECM will set DTC called "Regeneration frequency" that basically says its doing regens TOO MUCH.

A cracked charge air pipe or kinked vacuum hose would be an easy find. But there could be a much harder to find issue like a rolled or damaged seal in one of the many connections, some debris or other reason a leak is happening INTERNALLY, or a sensor sending faulty info that is still trusted by ECM as correct.
