Any chance you have a part number? I just talked to the only volvo dealer in town and he couldn't find it on his computer? I will take the old hose in tomorrow and show him.

But a part number would be awesome!!!

 

HALLELUIAH - I think I found it, certainly looks like the right hose.

02 2002 Volvo S40 Idle Control Valve Hose - Fuel Injection - APA/URO Parts, Genuine - PartsGeek

 

That link shows they only have one in stock. Must be a popular item.
RockAuto also has it for a few bucks cheaper.... $6.05

 

Success. Installed the new hose, cleaned the IAC - it wasn't that dirty, but since I pretty much had to take it off to put the hose back on, I hosed it down with carb cleaner.

Anyway, started right up and idled just fine. Took it for a short drive and all is well, drove it to work today, all is well.

If only I have seen the busted hose in the first place!
