Ah, I was thinking that is incredibly impressive mpg for a 90 ???Yes indeed.

Thats a good start, MPG depends on so much you cant compare, I drive with no air con (broken), mainly motorway at 70-85MPH fairly flat with one hill, every day out and back 70 miles in total and get 59.9mpg average, but my car has been recently serviced all through with new ish 17 tyres. Its a tdi 90 with 140k and new turbo to boot. cant seem to get any higher unless i go 64mph everywhere. I get about 46-48 at 80mphFirst proper run today of over 100 miles - I just ticked over to 55mpg briefly, which I’m fairly pleased with considering I have a lot of issues with the car, not least buckled 17” alloys and a leaking flexi (more gushing than leaking?). Looking forward to putting 15 or 16’s on, a remap and some aero mods to increase mpg. Of course the accuracy of the DIS may not be the best……
Maybe because less revs are needed to achieve the same speed?According to the A2 brochures the 90,s should be a smidge more economical than the 75,s. ?
Youll get there in the end. Cold starting could be a few things, glow plugs battery fuel filter, leak back from injectors etc. You'll have to check each one at a time. If your running turbo cleaner try and 'load' the turbo and low revs this will move the vanes open and closed more without too much soot which you get if you rev it lots. The soot is what you want to avoid. Revving high for long time is good for injector cleaning though I found.The only real issue I’m having with it is cold starting, takes 2 - 3 turns of the key and some gas to get it going but not everyday, maybe injectors are still a bit clogged. Confident the head gasket is ok, I gave it a good blast for about 25 minutes at 80 - 85mph (on my private runway) this morning and floored it briefly in 4th on an incline to over 3500rpm, so hopefully it makes a difference. Really smooth at those speeds too, no wobble or shaking at all. By the end of the journey MPG had dropped by 2.5, which to me is not bad at all.
60mpg is the gold standard for me. Need to calculate actual consumption when fuel is low again.
I remember reading that too but definitely not true in reality though ?According to the A2 brochures the 90,s should be a smidge more economical than the 75,s. ?
I get around 60mpg in both my TDi90s cruising at 67-70mph.
DIS consistently tells me I’m averaging low 50s in both cars however, strangely
I did roughly 40 miles today and the mpg barely moved from 52. Maybe 0.2 deviation across the entire journey. I always assumed it was the whole trip journey that mpg was calculated on, so that’s an eye opener for me. Is there a better way to calculate real average mpg, other than just taking note of where the needle is at fill up, how many gallons you put in and resetting the trip?IIRC my manual says that the DIS average MPG is for the last 35 miles.
