Car is 1.9 tdi 130 bhp ASZ Engine , noticed this week a pipe that runs across front of engine bay under Radiators , has corrosiion on the metal connector , think its the air con pipe long length going from 1 side to the other and it has a large metal crimp connector in middle . Need to confirm part number and if is the A/C pipe is it a job for the experts . Thanks Will try to upload picture

are you sure it is not a power steering line?

I'd just spray it with waxoyl and leave it

ac disconnection is something for the experts - quite dangerous if you get it wrong

Didnt bodge or someone have this issue a while back, think its a banjo fitting which can corrode.

That is what I did with my rusty looking pipe connections.
