is that alls they are an extra tenner? might be just as well buying the genuine thing then...the cost is negligable really.
 
Get the retro fit vw ones, they are £20 from vw dealer no need for postage or waiting for them to arrive and the clip on and work a treat. The dealer will prbably tell you that they wont fit your car but just ignore them. You want the ones to fit the mk3 - mk4 golf.
You got a part number and a price for them? I can order them through work and save me going to the dealers.
