Big turbo I presume?? 395hp is a pretty a 'optimistic' claim for a K04 car..

i know they've mapped a GTI with a GT30 turbo on it to just over 400bhp, so i reckon he's got one of those.

MRC did mention that they could overide the ECU code to tell it to send the right amount of fuel but that still doesnt solve the problem of why its over fueling in the first place....
they are going to change the fuel filter - will get them to have a look at the second PCV and another look at the MAF
then do diagnostics while the car is driven to try and find a faulty sensor.
after that f*ck knows what could be causing the problem unless its just a particuarly sh*t engine

What's your mpg like? Any white smoke on boost? Does it make full boost?

Are you getting any support from the dealer that sold you this car as if it were mine i would be demanding something! Technically they haven't they mis-sold you this vehicle as something it isn't, if im not mistaken. I hope you manage to get it sorted anyway!

mpg isnt great, car is definitely running full boost according to VAGCOM. no white smoke. i did get nearly 100 miles to a 1/4 tank recently wiht a mixture of stop start london driving and motorway which seems about right
