Are you sure you have identified the correct part number? Have a look at the drawing here.
Might the problem hose be #10 9129576?
When I experienced a similar issue to you it was #2 on the drawing. This is the inlet pipe for the HBV that connects to a spigot at the rear of the engine in the well of the 'V'. It was split under the hose clip. That hose is 90466222 and Autovaux got it for me for £7.60+vat + delivery about 30 months ago.
Incidentally the leaking coolant nicely doused the coil pack, which gave up the ghost shortly after.
No, unfortunately not. My car does not have a HBV but instead the pipe goes directly from the spigot at the rear of the engine to the bulkhead connector using the hose I identified in the earlier diagram. It has failed at almost the same spot as yours though with a small hole in the pipe just back from the connection to the spigot. I have managed to remove the pipe with difficulty and it just seems a shame to spend considerably more effort replacing it with a repaired hose rather than a new one.
