By the way Service guy was explaining to me - It sounds that the whole thing was clogged with carbon monoxide residue and the EGR became...eeer... crap.

I brought the truck in because the engine check light came on. It was on and off for several months.

I am guessing that the dealer is right about the EGR tube but the cause of the problem it is doubtfull. I never heard anyone here saying that they have a special service every 20k for flushing the injections.

The VX is being repair at the dealer right now. I can't go back there and just be mad without arguments.

Oh, one more thing. The dealer strongly suggested to change the serpentine belt. It is cracked at several places. So the whole thing would cost $75 part and labor.

Thanks,
Michael
