I used to have a BMW 2002, which needed a phosphate free coolant. Seeing as they both are steel block / aluminum head engines, I assume it's the same for a B230.

C. Why does my vehicle owner’s manual recommend a phosphate free antifreeze?
Some European car manufacturers recommend that phosphate free antifreeze be used in their vehicles. The reason is that the water in Europe has an extremely high mineral content. If you mixed an antifreeze containing phosphates, which are part of the corrosion inhibitor package, with the water they have in Europe, the phosphates in the antifreeze may “drop out” and form deposits in your cooling system that can lead to corrosion. However, this is not a major concern in North America, since our water is lower in mineral content, or softer, than European water.If you are interested in a phosphate-free antifreeze, Old World Industries offers PEAK? Global LifeTime™ Antifreeze and SIERRA?, the Safer Antifreeze.

Obviously, it's the corrosion inhibitors that are the problem with european based vehicles.
Ugh, never try to read that far into a post on this board. There's all types here... from eat and sleep volvo breath to hard core volvogasm. But you get the best of all worlds - folks here know more than the people that designed the things in sweden. The best q/a support you'll find anywhere, with no sarcasm, and little humor - just straight up the best advice you'll find.
Welcome.
