Spoke to a friend tonight he also have the new Navara. His consumption dropped to 7.3km/l while on holiday.
You most properly have blocked Cats.
You will know there is some little knoppie you need to push, Find a nice private road. Bliksem that Navara as hard as you can while pressing that knoppie.
Hi Grips,
Eerstens baie dankie vir die advies. Ek het net 'n dpf knoppie en volgens my verstaan is die dpf en cat afsonderlike items, maar tog verbind aan mekaar.
Ek het die manual gaan lees, en volgens Nissan gebeur die regeneration process automaties as ek vir 'n seker afstand vinniger as 80km/h ry op die oop pad. Ek kan die knoppie druk om die proses manually te doen, maar die boekie seg niks oor dit druk en ry nie. Die boekie praat net oor die bakkie stilhou, die knoppie druk en wag todat die proses klaar is.
Ek moet ook noem dat die dpf waarskuwingsliggie nog nie aangekom het nie.
Dink jy dis veilig om die knoppie te druk en die kar te bliksem op die oop pad? Of moet ek maar net sewe soorte kak uit hom ry vir so 60km sonder om die knoppie te druk?
As die handboek sê hy moet stilstaan as jy die knoppie druk doen so. Maar blykbaar werk hard bliksem ook goed. Seker maar soos `n stout kind as hy nie wil hoor nie moet hy voel
Ek het nou net die kar so 20km uit die dorp uit gaan ry - hard. Daar is beslis 'n klein krag verskil. Normaalweg sal die naald die 190kph merk maak, maar maak nou skaars die 180kph - met baie soebat daarby. Ek is so vinnig verby van die wambos hulle het seker gedink die SADF is weer terug met 'n moerse spoed.
Sal die bakkie se dpf vanmiddag druk en die proses laat loop, dan die kar volmaak en kyk of dit beter lyk.
Weereens dankie vir die advies.

in a turbo engine intake temperatures are massively affected by ambient temperatures, even when intercooled. In fact, generally speaking even more so when intercooled as the difference is higher.
first is boyle's law - briefly, volume , temperature and pressure are all interdependent and constant - so , as volume decreases either temperature or pressure or both must increase in proportion.
when you start with a higher temperature less dense gas you actually have to compress more - hence you transfer more heat to compress yo the same pressure.
in addition your exhaust is not cooling as well in a higher temp environment so more heat is transferred to the inlet side because of the proximity on a turbo.
if you have an intercooler it's running exponentially worse - in other words if ambient temp doubles , cooling ability is reduced by a factor (say 4 times)
Which all means that 10 degrees increase in ambient translates into far more at the charging point - say 20 or 30 degrees more.
that means EGT and every other temperature going through the roof, which in turn means performance drops, which means you need to burn more juice to keep to the same performance.
so yes.... high ambients do tend to reduce efficiency thus increase consumption dramatically on turbo engines....
Went to Swakopmund three weeks ago. Between Henties and Swakop the car went as limp. Took it to Nissan, apparently the boost sensor failed. Replaced it and the power was back, although not as much as I used to have. Again, consumption was lower than usual.
Got back home, took it to the local Nissan and complained about the same symptoms - which was met with "are you sure? It seems fine to us".
I must be a moron then.
On Saturday I noticed the parking brake (which was adjusted at the last service) got up to about 4 clicks. I am lucky to get it up to 5 clikcs if I use two hands. Noticed in the book that the standard adjustment is between 6 - 8 clicks - so I adjusted it accordingly.
I have not yet noticed a difference, but it is early times. Can this have an effect on the consumption and power? Surely it has to?
