Hi Guys.
Maybe a question for the experienced mechanics out there or some one who may have had the same problem.
Late 2014 Colorado LTZ 2.8 Turbo, on two occasions has gone into Limp Mode whilst working hard towing a Caravan up a long/steep gradual incline on the Hume Highway.
Once it is stopped and re/started all is well and keeps on towing with no apparent issues.
This happened twice on a long trip and also happened twice or three times a couple of years back.
The rig starts to clime the gradient and shifts back in the gears, the temp goes to about half, and the REV's hit about 3500, it is at this point it loses power and goes to limp mode.
OKI know what it all means and why it is doing it, to save the engine i expect but how dose one remedy the problem, other than those incidences, it never misses a beat and tows it heart out very comfortably.
Holden tells me little and say bring it in and we will charge you $100.00 to tell me what i already expect to be the issue a Over/Under Boost causing Limp Mode and a P0299 Code in the Computer, which happens to be the code for pressure in the turbo charger and/or exhaust pressure.
I had this situation once in my IVECO and it turned out no one had bothered to check the sensor relating to this particular situation when servicing, and never cleaned the sensor, and once that was done it never happened again.
So here we are any suggestions would be much appreciated.
