Hi there.
Your Country: New Zealand
Year: 1997
Engine variant: 1.8 GDi
Transmission: Tiptronic
2WD/4WD: 4WD
Fuel used: 96 octane
Approx km/tank: avg 350 town / 450 country
Tires: 215x45x75r
Intake: Standard
Exhaust: Standard
Mods: Catalytic converter removed after 122,000kms (no real difference except breaths a little easier)
I also have the Legnum 1.8 GDI. Doing long trips I calculated that fuel consumption would vary from 10ishL/100KM through to 13ishL/100KM. No rhyme nor reason why the variation except perhaps petrol age and brand.
My car was missing like it was running out of gas. I put foot down, and car would splutter. Take foot off the gas and would run nice. Problem disappeared after a few minutes and had no problems until months later when it did it again. Went away again, and finally happened again but real bad. I only just made it to the garage without it konking out. Could only press microscopically on the gas pedal, barely moving, without it spluttering and stalling.
Turned out that the high-pressure fuel pump was screwed. $2000!!!! I am so glad I bought a 3 year warranty, as the excess was a mere $75!
Car still CHEWS the gas. I get about 350km's per tank around town. Going up hills or towing, this car cannot do. Very little difference in acceleration occurs from when foot is 1/4 pressed through to fully pressed. I wonder if driving with wooden block under the pedal would make it cheaper to run, seeing it makes no difference in power nailing the gas pedal.
Oh yeah, it runs far better when no passengers, and on cold nights.
