My mate bought a 2008 3.2 DI-D swb, 144 000 km on the clock, very impressed with the car until the first tank was empty at about 440km, we took the paj to brooklynn mitsu and they had it for about 2 days, they told us nothing wrong with the paj fuel consumption looks good all fine.
Week later 430 km tank emty

We took the paj to midrand mitsu, 4 hours later the guy phoned back and said the paj took toooo long to shift gears and thats the main reason for his problem they changed gearshift settings at no cost,you can feel quicker gearshifts now. it has now been 2 weeks later the paj went to mosselbay and back, the best consumption on one tank @ 125km/h 490 km, my paj @ 125km/h 750 km.

He phoned freek at mitspro explained the problem to freek, freek gave him the advice to make sure that when he drives, he must take the revs up to 2500rpm before the car shifts gears, he also explained to him that the gearbox will adapt to his driving style because presently the paj shifts at 2000rpm and when shifting on that rpms the paj will be heavy on juice. now i took the paj for 1 tank dubble cheked the rpms and the gearbox to shift @ 2500rpm, Still no change in consumption.
I know my 2004 swb 3.2 is a manual, but can a auto 3.2 DI-D swb give a consumption like this!

Can anyone help regarding this problem?
