As said morons!
Heatshields are a standard fault on Mk3's - Just take it off, they aint needed.
Brake fluid - well it is said that it deteriates over the years, well I havent changed mine since I bought the car which is now nearly 9 years ago.
Rear pads - can you manage to take a wheel off? Hope so as you'll be buggered if you ever get a punture!
Have a look yourself, with wheel off as you will be able to see how much of the pads are left. 2mm or less then yes probably will need changing soon. If more than 2mm forget it.
