Polo Gti recent high fuel consumption!!!

[kevvie]

Funny, I was thinking exactly the same this week. Normally a trip home from work averages 8-9l/100km, the past week it has been 10-11. Don't know if it is related to the humidity, but I was wondering. Car is due for a service in a couple of weeks, so will be keeping an eye on it.

Of course if you have consumers like AC on you are putting more load on the engine, goes without saying. If its over the top consumption then have the live data read in cruise conditions, not stop start stuff, and watch the injector pulse width and lambda figures

Jeeeesus man haha! I get about 440-450km (55L tank) usually & that's with K04 and a round trip to work of about 11km per day (10 mins each way) which is hardly good for engine wear or consumption either! You must be sitting in neutral on the freeway for an hour or you have a REALLY heavy foot!!

What about recent hot weather we've all been going through and heat sink etc?

far out Chuck....300 to 360 per tank is not very good.
having said that, get caught in traffic on a 40 deg day with a/c on and it will drink plenty.
my little trip computer (2) is showing between 8.6L to 8.8L/100km. so on a 45L tank thats just a bees d*ck over 500km per tank.

i do enjoy a bit of 2nd & 3rd gear boost but i should still be cracking the 400km per tank mark surely? AC hasn't been working overtime as im concsious of my crappy fuel consumption

My last mod was a cat back exhaust system from Methams...since then the fuel consumption has been terrible to say the least

Any hints as to what to look at when in for next service?

Jmac: "have the live data read in cruise conditions, not stop start stuff, and watch the injector pulse width and lambda figures" - is this something that can be adjusted quite easily?

I struggle for 385km to a tank in drive-to-work conditions.

I enjoy a bit of lead-foot action at times, but even highway stuff only gets me around 450 at best!

How much are you guys filling up each time you visit the tank? I can squeeze in 45-47 litres each time...by pressing that little round black button next to the filler hole once the nozzle clicks, it expels all the pressure in the tank leaving more room for actual petrol. I get over 600km regularly - I do like to give it some as well (averaging about 7.3-7.5l/100 atm). When coming up to a set of lights, I like to revmatch downwards and coast to a stop which really helps me save petrol and keep my momentum in case it turns green!

The only little black round button I see is the one that locks the gas flap.
Do have a movable sort of nipple-shaped protruberance just inside the filler opening, could that be it?

Yeah, you'll hear a hissing sound when you depress it while filling.
