I have a 61 plate Passat CC 2.0 and have a slight tapping noise from the fuel pump so every time when I accelerate its lumpy then goes away and sounds like my engines pinking.

First posts normally go in introductions else you could get a free fix and we never see you again!!!

Your car spec says 0, only what I've added from this post, minus engine type.

If you says its pinking I would guess its a petrol engine.

Fuel pumps in the fuel tank do make a buzzing sound but that won't cause pinking. Pinking is uncontrolled combustion maybe you have a faulty knock sensor.

You need to get your motor scanned (preferably with VAG-COM\VCDS) for any error codes logged in the ecu and post them, that will save a lot of guessing and check systems out.

Post moved to correct section as OP can't read sub form titles. ;)
