FLAME ME!
The ceramic honeycomb inside my diesel particulate filter is crumbling. A helpful local expert TDI mechanic used his boroscope to confirm that the ceramic is crumbling.
According to another TDI mechanic, the crumbling of the ceramic filter was due to the filter experiencing heat over its tolerance spec. This occurred due to a hole forming in one of the exhaust tubes, which itself melted due to a crack forming in the flexible metal EGR tube, which melted the exhaust tube (and my airbox as well.)
(Talk about bad luck!)
I know that the EGR system and the air intake and exhaust systems all need to be cleaned.
What would you think of this repair of the DPF?
I disconnect a couple of exhaust tubes etc. from the DPF canister.
I cut open an access hole in the top of the DPF canister using my dremel or a metal snips.
I use a vacuum tube and a pick to slowly break apart the ceramic and I vacuum out the ceramic. I use a cheap $11.00 Ebay boroscope for my Android phone to inspect my progress.
I predict that I only need to tear away a cylindrical "tunnel" in the ceramic to allow the exhaust to exit the DPF unimpeded. One reason why the TDI ECU is throwing a code is due to the incorrect pressure exiting the DPF.
I will use 45% silver solder to weld the access hole I cut in the DPF canister. Have you had any success using 45% silver for VW stainless steel?
I will get the 2009 VW TDI Jetta tuned.
While I am at it, I will probably get remove the EGR as well, as it ultimately precipitated the over heating of the DPF.
(I only drive this TDI on Pitcairn Island, so I am not concerned about anything. Maybe an angry albatross or 2. If the albatross get too fiesty I can always wear an albatross around my neck!)
What do you think? Any suggestions? AND PLEASE FLAME ME!!! Thanks. Your flames make me miss my family and being mercilessly teased by my 3 older brothers!
