what are the symptons of the pedal box being on its way out?
i have a slight whine when i let off the accelerator and when i put my foot down, you can only hear it at low revs, not very loud at all!!
i was thinking maybe the diff or a belt like the cambelt, the diff went on my Mk4 Polo 6 months or so ago after 122k tho, that was a lot louder and jolty
any suggestions?
Strange Noise....
The safety recall was offered to all Polo GTi owners - you could go into your local VW dealership and ask them to check if it has been done or not by looking it up on their system? If it hasn't been done yet, it's free of charge due to the nature of the work. Mine took a day, I dropped it off at 8am and picked it up at 5pm. It's worth knowing if it's been done or not 
You can try ringing VW Customer Services and ask to be put through to the Recall Department (bit worrying that, having a whole department dealing with recalls!) and I'm sure they will be able to tell you whether it has been done and if not how to arrange for the work to be carried out.
Good luck mate.
