Ok so for the last four months constant engine light, stealershit put a new DPF, two days later an engine light, stealershit put on a new EGR, picked it up last friday (Jan.21st),today no Jake Brake.... can anyone give me a heads up on what the problem might be ??? I would like to have a little edj-ya-mication to head off the stealshits bullshit excuses! thanks for any info

 

pull the codes and post up please

 

Sounds like your turbo has taken a dump..... quite common on early stock 6.7's

 

exhaust brake, not Jake brake just passing it on from what Ive been told in the past

 

Actually its a turbine brake

 

no codes I just noticed the difference between how it downshifts now compared to how it used to shift. It use to hit real hard before,now you can't tell the difference if its on or off shifts the same

 

there is an on off switch in the starscan settings, have the dealer check there first (will not throw any codes)
