it can't be the lambda probes... or shouldn't be - they're narrow band & do nothing as soon as you're driving about. they're for MOT emissions only. (zero load)
new plugs (the right type), air filter, well serviced, fuel filter.
All the above assumes that the MAF & MAP are working correctly.
On our Ibiza cruising on the motorway we could get 350-380 miles / tank. a lot of it depends on driving style

MAF's don't always work from new. well worth logging.
Also check for leaks or kinks in your pipework

Right i know this is an old thread
but am averageing 20mpg and am driving like a granny..Theres no boost leaks and the FPR is fine...
I do have a De-cat tho...But it was like this before i had it put on tho....

Any codes? What are your mods?
Have you done a brim to brim calculation? Personally i dont trust MPG displays in cars.

your decat will always smell slightly. There is no more cat on it, hence the fact you fail MOT without one.
It can increase you mpg slightly having this, but if I remeber correctly regular consumption should be around 35mpg? So then 20 is very low.
service will do it good: spark plugs and fuel filter is something which should be really changed regularly.

On a motorway run last night i was getting about 33mpg ish. Car is standard apart from a Green panel filter and was serviced 1k ago.
As Mork says, I regularly get 350miles out of a tank. That is driving 85% motorway @ 80mph and 15% pottering around town.
On a long run and sensible speeds the 1.8T is quite a good little engine, I quite comfortably get 36mpg average out of it.
Driving it fast and hard I get something nearer 26-28mpg so...
Don't thrash it everywhere!
