My car is now sorted. The issue I had was...I had not done the priming correctly, therefore there were lots of air in the fuel line. I did the key On and OFF cycle for over 20 times (as advised by Volvo) and then car started straight away.

If you remove any fuel system line (like a hose or a banjo bolt or high pressure pipe etc), it sucks air in then stops sending fuel to common rail. When you turn the key to ON (ignition on) and if you have air then you could hear fuel flowing in there inside the fuel filter housing under rear passenger seating location. So you have to prime until you hear nothing but whining noise. This is achieved by above method, ON and then OFF
