Any idea why the egr blew. Did you notice a loss in power last time you drove it? I had almost the same kinda thing happen. But mine was cause of precats melting down, which in turn blew up my dpfe sensor and the hoses connecting to the exhaust. After all that it would not start, becuause the exhaust was to plugged up. I would assume you would notice the symtoms leading up to this, so this may not be the case. Just a start though.
