I just got a 6.4 ... 55k miles truck rocks, but i discovered coolant leak on top of the egr , the hose that supplies the valve with coolant is leaking at inlet and outlet, (one from cooler to egr) , and i have lost about an inch of coolant in the last few days. HELP I need to fix it before it turns in to an issue
As if that was not enough

i got a new MIL P0607 CONCTROL MODULE PERFORMANCE... So i took it to the dealer..
Dealer flashed it.
and two days later BAM

LIGHT is back .. seems if i erase it, i can drive all day and it wont turn on, it only comes on right on start.. like every 2 or 3 starts or after sitting all day.
Replaced the batteries , Dealer does not know Whutdfuks up they are blaming it on my mini max ... called H$S and they assured me it was not the tuner.
IM ripping my hair out with this dreaded light!
Any help would be great
Thanks in advance!
