What year is the car, can you carry out a paper clip test to see if there are any fault codes stored?
Could be MAF, could be temp 2 sensor, could be lambda sensor.

You cant do the paperclip test on Vec C's mate.

The brakepedal version of the paperclip test then.

Well I've just replaced the mass air flow sensor on my golf v5 , and it's like a different car.
No uneven idle anymore , with smooth power delivery , and goes alot better as well.
If you think about it , the maf sensor is the first point where the ecu and management system electronically controls the running of your car , so if there is the slightest problem there , it will magnify further along the lines , overfuelling and so on.
So I'd say change it , you have nothing to lose , only make things better hopefully.

My car is 53 plate.. It is still under warranty (via nissan dealrship) so if the mass air flow sensr is faulty will it store a fault code ??

What is the paper clip test ????

its when you put a paper clip in the dia port and the dash flashes a number of times and gives you the number of the fault
