Hi guys I hope someone can help that has had a similar issue

i have a 2015 outlander automatic that is perfect most of the time although up some hills and at speed (60mph+) it will completely lose power but not throw up any fault codes at all.

can anyone offer any help??

 

Split intercooler hose is one very likely possibility due to high engine loads, so is a sticking EGR valve. Initially both will have no codes until DPF starts to block up
