I won't be buying anymore Miller's. Got enough for one more tank I think. Ive event tried the double shot of putting 4 lots in one tank and still no miracle
As for the CC-1 map, it's great. Much more torque, car really pulls now and pulls all the way to 5k. As standard it wasn't worth going past 4k, that's all changed with CC-1. MPG wise it's definitely not any worse. Problem is it's now even more tempting to boot it a little more often but I have seen 60.8mpg average on my 35 mile trip to work which is a mixture of A/B roads and town traffic (Newcastle). To be honest though I reset Trip 2 every tank and over the course of a tank i'm getting 48mpg which is 2 up from before the remap.
Engine was mapped with about 6700 miles on the clock so quite tight still. Hitting 9k now and MPG going up nicely. Only thing I have noticed is a bit of DMF resonance if you tried to boot it below 2k in the wrong gear as a whole load of torque comes in. Drop down one and problem gone. No clutch slip what so ever so far *touch wood*.
Thats where you fill tank but on older mkI leons and ibizas i think you could squeeze in some more using a vent button, fills the expansion space in the tank.
doesn't sound a good idea to me
Me too, have done it since day one with the Ibiza, and with the Passat, never had any leakages.I fill mine to the brim all year around and i've never had a spill or expansion problem
I too tried the double-dose - I too found it made sweet F.A difference! At least there is only enough left for a final tankfull....
Am seriously considering a remap, but so much choice I am a bit unsure where to go for one.
What sort of power/torque do you see with the CC remap? Don't want a clutch-frying remap so it looks at if no more than 300 ft-lbs is on order.
Oh decisions decisions!
So long as your cap is air tight and won't leak, its fine to fill to the brim.
Diesel won't expand like petrol will as they have different flashpoints. Diesel needs alot more heat to get warm enough to evaporate off (+55 degrees) where as petrol evaporates off at very low temps (-43) so needs room for expansion.
Thats why diesel is deemed to be safer, and also why you very rarely smell diesel when you pull up to a filling station (unless someone has spilt it) but you can smell petrol.

Thats the easiest way to find outThanks for the explanation.
i suppose you wouldn't know your cap wasn't airtight until you swung it round a left hander and diesel sloshed all owa t' place !!,

My remapped Mk4 Ibiza TDI 130 averages 520 miles per tank, over the last 3 tanks that's an average of 48.5 mpg (trip computer reports average of 50.4, so not a million miles out).
Can be arsed reading back through the thread to see if it's been mentioned, but ages back we had a "Mk4 Ibiza most miles to a tank" challenge and IIRC the record was close to 700....

Its unlikely that the cap wouldn't be an airtight seal as manufacturers don't like buying new engines for you because their badly fitting fuel cap let water in.
I'm pretty sure that you would be safe to do this, but if you do notice any leaks then obviously don't put so much in next time.
thas too late now wi warning, filled right up t top (72ltr), swung round said lefthander, diesel spewed all owa t' place, motorbikikalist following slid on it, he went for a burton, shouting "hoy yer ******" as he went arse over tit, I shouted back, "hoy, don't blame me, blame 'daveyonthemove'"
