The engine is in first class condition: 7.5L/100kms, no oil usage, vehicle has done 220,000kms in Southern Africa on good roads.
On first starting in the morning starts relatively easily. Thereafter unpredictable often requiring several attempts.
The battery is new and to the right specs according to a reputable auto electrician.

That's actually pretty normal. It's just the engine warming up. Even my friend with a late model Acura has the same prolem so she warms it up before driving. I've heard experts say that warming up your car is just a waste of gas so I presume that the initial knocks are not to be worried about. Something to email Click and Clack on NPR about but I really don't think it's an issue. When I've had two cars run into the 200,000 mile range it didn't seem to be an issue. I always changed the oil before or at about 4k miles.
Take the car out for a long drive and enjoy it. And don't worry.

Could be several things; MAF ( Mass air Flow) sensor, (Yes you should have one), could be fuel pump on the rail or the filter next to it, could be electronic idle controler, clogged injectors, ect ect, a Volvo dealer can do some simple checks of the actual components and tell you, but have someone else fix it!

do a fuel pressure check it should be around 38-40 psi, if low check fuel pump relay and fuel pump

If the air pump system is setting a fault, then the check valve is probably bad. If it is not addressed, eventually exhaust gases can run back through the air hose to the air filter housing and destroy the MAF sensor, causing these types of problems.
The fuel pump also fails and is a more likely cause of the stalling, and it wont set a code.
