2008 1.9 tdi bluemotion or GT Tdi

[dodds-gttdi]

I drive a 2004 GT TDI with 90,000+ miles on the clock. I am finding at the minute I am getting somewhere between 480 and 550 miles to a tank, daily use, without trying to be frugal. The record miles to one tank was a smidgen over 600 meaning an average of 55mpg. Normal day driving sees me anywhere from 45-52mpg.  

Neil86, have you any major mods on your car? I think my car drives marginally better with the remap (slightly more frugal) and much much better when using my 16" Alloys (winters). Replica wheels will see fuel efficiency dive down, as will poor servicing, blocked EGR valve, fithy air filter, old oil, etc. Do you know when you car was last serviced? Lastly, when I lowered my car I noticed an increase in mpg too.

I service it myself genuine vag parts every 10k long life quantum oil. Although I wasn't happy with the quality of the genuine air filter not as good as the mahl one I had previously.

Major mods eibach coilovers noticed better fuel economy with them set low.

18x8.5 wheels bowt it never been remapped.

Not had egr off as I wasn't sure if disconnecting it and putting it back on would throw up a fault code or if there's any seals.

What would put me off a TDI (from any manufacturer) is the inevitable wearing out of the fuel system. Every person I've known with a VAG 2.0 TDI (140 or 170) has had a fuel delivery issue (pump / injectors) of some sort. Likewise common rail diesels from other marques - I had 4 injectors go on my last diesel, likewise with my sister's car, a colleague spoke to me today and said his Merc 320CDI is playing up, and another colleague had a couple of new injectors on his 220CDI a month ago. In the past year when someone has mentioned a problem with their car to me, if it's been a diesel it's been high hundreds maybe thousands, or if it's a petrol it's been a coil or sensor at only tens of pounds.

Anecdotal? Yes. The good thing about using more fuel with a petrol is you can plan for it, but for some people the surprise cost of a couple of injectors / fuel pump is quite hard to stomach.

I'd quite like a fast diesel as an every day car, if it delivered good fuel economy with solid reliability. From past experience though, I just can't be bothered with the surprise costs and unreliability.

Getting back on topic - my experience of a 170 GTD and a 105PD is that the GT is far more driver orientated, but the 1.9 was easier to get good mpg from, unsurprisingly.

i have had no fuel issues with mine--just bloody turbos

Iv got the 140 and it seems to drive ok. Not got the kick I want but regularly returns 55mpg

Seems to miss a little bit on startup. So I may have problems with fuel system :( only just bought it too

I get 40+mpg on the way to work, 35mpg on the way home(lots of traffic) and as much as 55mpg on a really good M/Way run, if I drive like a granny.

...and don't forget, Tax and Insurance is cheaper in a diesel too.
