Howdy folks,
It's been nearly a month since this work was done, but I wanted to apprise everyone of a DPF issue I experienced, in case it helps someone else with a similar issue.
I took my car into the dealership after the Check Engine Light illuminated (NOT the DPF light). Upon scanning the car and conferring with VW Technical, the dealer was instructed to replace essentially the entire exhaust between the turbo and rearmost muffler.
Upon picking up the car and pressing for an explanation, the shop foreman gave the following rundown.
The CEL was caused by a clogged EGR filter. This was due to a flaw in the DPF. VW was aware of this problem with some other early CR diesels, and had made running changes to the DPF and ALL the catalysts. So the parts were all replaced with the newer versions, including the newer-style two-piece DPF/cat assembly. In addition, the ECU was reflashed with revised software that will change the cycling of the regen function in some way.
Again, this was all done under warranty, and I've noticed no difference in the car's behavior. I've called VW and had them note this in my file, should the problem recur in another 30K miles. Hopefully it won't recur, but if it does I am so far impressed with VW's responsiveness in my car's two warranty claims (see my sunroof leak issue in another thread).
When I get the chance I hope to get under the car and take some snapshots for the benefit of the forum.
Meantime, here's the list of parts replaced in this operation:
(2) 1K0-253-115-T GASKET
(3) 1K0-253-725 CLIP
(1) 1K0-253-725-E CLIP
(1) 1K0-253-120 TUBE
(1) 03G-131-547-H GASKET
(2) N-101-560-09 BOLT
(4) 1K0-253-115-AE GASKET
(2) 1K0-253-725-B CLIP
(1) 1K0-131-649 BRACKET
(1) 1K0-254-401-R CATALYST
(1) 1K0-254-706-LX EXHAUST PIPE
(1) 1K0-254-401-T CATALYST
(1) 1K0-253-725-B CLIP
(I think below is the DPF part number
1K0-253-120
Here's the writeup from the original diagnostic:
"Diesel particulate filter failure causing EGR filter to clog up. VSD, GFF, follow test plan all OK. Contact tech support, ck basic settings 78 and 241, tech support suggests particulate filter failure causing EGR filter failure, must replace both per tech support. Replace SO parts as required, erase faults, generate readiness. Unable to continue test plan as comp. w/plan was updated and GFF data log erased."
Hope the rest of my time with the car will be as utterly trouble-free as the first 36k were prior to this issue and the sunroof, both handled without hesitation under warranty by VW!
