http://www.myturbodiesel.com/1000q/glow-plug-recall-pd-tdi.htm This summarizes and clarifies what, why, and what to do about post glow plug recall cold start temperatures. It applies only to 2004-2006 VW TDI. While I wouldn't start it, this seems like it would be a decent class action suit since it's easily understandable, many people are affected (probably almost everyone who lives in a cold area who had the glow plug recall done), damages are easily documented, and it's a big FUBAR on VW's part. My best guess is that they decided a a rushed recall vs. a few damaged engines from glow plugs was the lesser of evils. I'll start an informal poll for those who have pumpe duse engines only (2004-2006). You can select multiple options since some of you may own multiple TDI.
