Not quite sure what is wrong with this "B" series...

[mwilson]

M2 Freightliner with a "B" series still under warranty coverage......fuel pouring out of the exhaust.....the after treatment system is certainly toast now...
Seth said it was idling away and then the white smoke started coming out of the exhaust...

Will update.....

Stuck float, no doubt

Give it some Seafoam, all better soon.

I’ve seen DEF seep out like that, but fuel?

 

[NIsaacs]

I am guessing there is no aftermarket for that exhaust pipe

 

[mwilson]

I think it just had the injectors replaced so maybe there was a bad one, like really bad??
Will see what they found out...
But the idle did not increase?? Maybe it wouldn’t if just one was pouring fuel out of the tip??
Kinda curious about it..

.fuel pouring out of the exhaust.....the after treatment system

I KNOW WHATS WRONG!!!!!!!

 

[mwilson]

I don’t know if a bad doser would do that or not...

I don’t know if a bad doser would do that or not...

That was my first thought, but I don't have any first hand experience with the late model stuff.

 

[mwilson]

No doser on that set up for fuel, does it with engine timing. I had to go ask....

Reading the work order I see it got a complete set of Cummins Reman injectors (which is what we must use under warranty), a reman DPF cartridge and a reman SCR cartridge.....probably gonna get all that again....

 

[mwilson]

BTW, the original complaint was "Coolant coming out of exhaust" so we at least have a different fluid running out of it...progress.....

 

[mwilson]

And yes, Cummins would have told us to do the injectors and such.....you don't go out on your own when dealing with Cummins Rapidserve Warranty....unless you want to pay for it yourself.....

 

[TFucili]

Any verdict?

 

[mwilson]

Saw it out back yesterday, Will ask if there is any progress this morning...

Yeah me too, had a stalagmite at an exhaust joint big as a grapefruit from dried AdBlue.
Stuck AdBlue Injector, tank was empty within 1000Mi.
