I hate everybody equally.

I had one of those Mk4 Golf TDis and ran it for two years from new. Experience tells me that you're deluding yourself. It doesn't pull at all until it gets to 2500rpm then as usual it's all over by 4000 rpm. How narrow does a power band have to be for the dieselistas?

A 1.9 PD (115/130/150)pulls reasonably from ~1300, a non-PD (90/110) one a bit lower, and the torque peak for both is 1900- and if it was a PD130 they're noted for the particularly surgey lump of torque at 1900ish- it's really noticeable on a good one and makes the car feel quicker than it is (though performance isn't bad for real). You're right about it all being over by 4k though- the later 2.0 16v is better, but at the end of the day diesel only burns so fast, I suppose.

Experience tells me you're either exaggerating about how bad the one you had was, or you actually had one with issues. What model / BHP was it? > It doesn't pull at all until it gets to 2500rpm then as usual it's all over by 4000 rpm. Mine pulls strongly and smoothly from about 1200rpm right up to just past 4k rpm if you nail it - point is you don't need to nail it right through the revs to make progress, unless you want to. In fact not one of the VAG TDIs I've had (and there have been a few now), have lagged like you've described, bar when the usual MAF issue rears its head. > How narrow does a power band have to be for the dieselistas? Given mine is doing an indicated 120mph at around 4k RPM in top and is happy enough to still pull the same gear from 30mph upwards if you can't be arsed to change down, I can see why the power band is 'narrow'. ;-) The Vectra CDTI I had - yes, the box needed to be constantly stirred - perfect example of a modern 'narrow band' - horrid car. I'm not saying it because I tend to favour VAG stuff, but I've tried quite a few other modern diesels (PSA, Ford, Fiat, Vauxhall), and none of them have seemed to get the combination quite as right as the VAGs I've generally had when it comes to power delivery / economy / smoothness... hence why I generally tend to go back to them. -- JackH |
