I have a sooted up tail pipe now,only difference is the recall change in the ECM the dealership did ,is this normal?

 

there should'nt be any soot at all if stock!

 

I've had at least two techs at different dealerships tell me that SOME soot is normal. The most recent was a few days ago when I was getting my turbo cleaned at a dealer in Tucson. I wouldn't say my tailpipe is heavily sooted, but there is a very light coat and has been for as long as I can remember.

I'm not particularly worried about it. The truck regens normally and there is no visible smoke coming out if the exhaust. I guess it could be said that the DPF traps most of the soot but a small amount gets through over time.

(BTW, I had the J35 recall performed last summer but I was having some soot in the tailpipe before that. I believe the J35 recall adds more regens, which may account for the extra soot. Just my opinion.)

 

In july I had a turbo replaced and they flashed it. Now it runs like a pud. Just got back from another dealer for another turbo(2k since july, and I've had it to a dealer inbetween that didn't do a thing. ) still making a huge whining noise. and I can leave a good trail of smoke! Goes back on Wednesday. By the way. Love the truck. The turbo is due to the replacement being faulty. Anyone in minneapolis drive a 08 6.7 I can go for a ride in? Just to verify new drivability?
