another member if the flatspot community. try replacing your maf sensor,if not then your n75 valve

Hi you mean the revised d diverter value , i,m sure if the maf sensor was faulty it would show a fault via vagcom...

What is your mileage?

Have you got any other modifications?

Think it may be worth going somewhere where they can do some logs and see if it's boost related, or whether other parameters are out. Might cut out a lot of cost and guesswork.
