Had this problem on my Alfa 147 52 plate. Got the pipes replaced and
all was well. I did have a dealer warranty on it at the time and the
power steering leaked after owning the car for just over a week
(bought it in 2005). Took it back and had to fight to get it repaired
under warranty, apparantly the dealer covered faults in the power
steering system but that didn't include the pipes! I argued that the
"power steering system" should include everything to do with it and
they caved in. btw the bill was about £250 if I had to pay it.
Anyway, I'm going with everyone else here and it'll be the pipes/
hoses, whatever you want to call them, leaking. Alfa dealer will most
likely charge a couple of hundred quid. Take it to an independent
garage, if you know a good one, for a look if you are not sure how to
do it yourself. Probs cost you less than half than at an alfa dealer!
