Between 4000rpm and 5000rpm i have lost power. When you hit 4000rpm you can feel the acceleration drop, then when you hit 5000rpm its like the turbo has just kicked in. It is an standard MY02 with 9000k miles on the clock, i've booked in for next tuesday, but what is it? MAF sensor??

 

Fuel surge?

 

ROFLMAO!! Any hints SB?

 

After 9 million miles you must expect some engine wear

(10500miles on my MY02, lack of power becoming evident across the whole rev. range)
