[s-cars] 3071 turbo & Pastore RS2 code question - MORE INFOupdate!

[Mark Strangways]

GO FOR IT :-)

Just do it :-)

But if things go bad, look at those hoses :-)
Seems we always look for the most difficult repair first, never look at the 
simple things.
Ahh, human nature I guess.

Let me know your thoughts on the 3071 please.

Mark
