The MK6 Fuel Consumption (Most / Least per Tank) Thread

[stockt12]

That's awesome! You'd be doing plenty of highway to get the GTI into the 700's?

Yeh, a LOT of highway kms to and from work mate.

This is what I've been getting out of my 118 tsi - total average of 6.0 l/100km since I bought it and now getting mid to high 5's most of the time.

TSI 118 Fuel Consumption Increase

Guys

My fuel consumption which has averaged about 7 lit/100 km has suddenly shot up to above 9 lit/100 km. My driving conditions have not changed, mostly highway driving. I recall there has been some discussion on fuel consumption on TSI 118's but I can't locate it. This increase happened sometime after the last service at 60,000 km. The clutch plates were also replaced then because of the DSG shudder during that service. I have not felt the DSG shudder since the clutch plate replacement, although the car feels a little underpowered sometimes. I am taking the car in for 75,000 km service tomorrow. Anyone having issues with increase in fuel consumption? Any advice?

Regards

Mabye ask VW when you take it in for its service tomorrow if they uploaded a new software file onto the engine at the last service?

The 118TSI's initially ran far too lean (not enough fuel = engine runs very hot and can cause engine failures) when they were first released in the MK6 shape and VW has released upgraded software several times to make the engine run richer (use more fuel = engine runs cooler and is safer for the engine). If your software was upgraded at your 60k service, then this may well be the reason why your car is now using another litre or two more fuel per 100km.

Re: TSI 118 Fuel Consumption Increase

Just a quick question - of vw uploads a new firmware to the engine; will it affect the Polar FIS+ that was just in the group buy?

Thanks for the tip, Lucas.

Out of interest, have you changed your tyres recently?

I have averaged 7.2 l/100 km but when i switched to michelin pilot sports 3 it is now averaging 7.8l/100km. Disappointing, but i love the cornering ability and wet weather confidence!

Though that doesnt explain the hefty increase in thirst.

I wonder if they havent installed something correctly like a spark plug, new air filter. My car felt peppy again after the 60,000km service.

No. The FIS+ works by interfacing with the car's CAN gateway on the CANBUS. Updates to engine/transmission/etc module software won't affect this.

Ive hit 950 kms, five times consecutively, before fuelling. Dat diesel.

I find i get a ~ 1l/100km lower reading if im doing 120 , when comparing with 105

Cheers mate.

Econo run back from Cooma a few weeks ago 5.9l/100km, not bad for a stage 2 GTI

The only thing I am a bit worried about is the fact that the Turbo only kicks in around 3500rpm and I rarely shift that high (mainly around 2-2.5k) it just doesn't need it...It has me wondering if it is bad that the turbo gets so little use.

Turbo doesn't just switch on at 3,500rpm. It is boosting all the time just not at full limit. So it is always spinning with very mild boost at even very low rpm. If you want to know how, then the first 30 to 60 seconds on the 160PS engine after a cold start is turbo only mode. The supercharger boost is not used although the clutch engages.

Sounds like you should have bought an na rather than a turbo

But of a shame really

Even at idle the turbo is spinning...although its not actually generating boost pressure, its still "working" as such even if you never revved it above 2-2.5k RPM.

does any1 have any updates on fuel consumption on the 147tsi highline...ive just put a deposit down on one and hope to pick it up by end of March!
