Engine goes into limp mode when running at 110 kph

[pcook29]

Hi all,
I can drive all day at 100 kph.
When I speed up to 110kph, the car will after 5 ks suddenly lose most of its power.
It will still drive but have no grunt.
It is a 2012 mn triton 2.5 turbo diesel, with 60,000 km on the clock.
The power will return if I slow down to 60ks.
Any ideas?
Thanks
Pete

Just noticed oil of some sort leaking from the pipe going into the rear of the egr cooler.
Could this be a problem?

[coughy]

no mate i would be getting the scv checked and probly the rail limiter looked in to as it could be a lack of fuel thing
ohhh have you changed the fuel filter??? use genuine it better than after market
if fuel filter is full of crap it would be doing that

Thanks for the advice.
Dealer reflashed the ecu.
They forgot to check the oil leaks.
They quickly rushed it back to the workshop and degreased the engine.
Have to take it back in a week.
