Thanks guys, I cans ee the front section pipe has some corrosion on it (not leaking ) - I think as I don't have an undertray the water has done its damage. I will try and wirebrush off and grease it up. I will have a look at the other 2 sections to see how bad they are.
I changed the power steering pipes on my old polo 2 - 3 years back and the pipes came in to sections and VW charged me £250 for it

Sorry this questions is a bit off topic - I am going to change my petrol tank on Friday - Anyone know if it is a big pain to do it. I will have someone to give me hand.
Thanks guys...much appricated.
