Thanks for taking the time and helping me.

I ran the leak off text 29,000 down to 24,400 in 60 sec --4900 loss just failing. Ill pressure it up and check for leaks this weekend.

I will do a complete egr tune up. I allready changed the DPF and reset it. I also cleaned. + tested doser.

Knowledge is power, and sharing is caring thanks!
