Gotta love Tdi economy

[Evaded Motorsport]

In the Polo according to the trip computer upto Maryborough from Brisbane I was averaging 4.1l/100km. Most I have ever had from a tank though was 910km although I do have a bit of a led foot.

Do the ventectomy mod and you will get >1200km at that consumption.

(Or you can just use the expansion tank vent button manually.)

the venectomy is a fantastic mod you can squeeze a wee bit more than an extra 15L into your tank!

VERY HANDY!

Ventectomy?

I tried looking at the links but any images are not there. Anyone explain what the process is?

I haven't been game to run past 0km remaining on the computer. Never got more than 53L in so far. Anyone know how much the tank+expansion chamber actually holds? (how much further one could go in an emergency before running dry. I did run my first petrol car bone dry (carried a spare fuel can) to establish actual capacity. I understand it is not so good to run diesels dry but I thought I read somewhere that VW diesels have self-priming pumps.

Many moons ago getting a Greyhound bus from Brisbane to Melbourne, we got to Tugun and ran out of diesel 50yards over the road from the Shell station. (Someone forgot to fill up.) But we had to wait 3 hours for a mechanic to come to prime the injectors.

i wouldn't recommend running the TDI dry (or any other car for that matter)

i'm not sure how much it actually holds, I just know it a substantial amount (for such a small mod)

Pics are there for me. I think you may have to join TDIclub to see the pics. Highly recommended to do that - loads of great information.

Okay, found them.

Not something I would do. All fuel expands, diesel as well. It would be naive to say it doesn't carry some risk.

Have read *extensively* about thermal coefficient of expansion of diesel fuel via the TDI club and other references. Even petrol has negligible coefficient of expansion. Pressure is unchanged in the same conditions. There is no increased risk. Feel free to do your own research....

i wish i had a diesel

last one i got in at work the needle was a bit bellow 3/4 and it said 780kms left in the tank . . . my mouth droped
