NEED HELP Cold Start issue on my 2004 2.5 TDI

I have just bought a T5 2.5 tdi 2004 it’s got 218k miles full service history had a new camshaft and water pump at 190k and serviced at 212k miles last. When I bought it I drove it 5 hours home with no problems it started first time and pulls well in all gears. Over the last few weeks I have been going to start it from cold but it takes at least 10 secs sometimes to start once it started it runs fine with no smoke mad will start the first turn of the key when warm. Has anybody had a similar problem with theirs?
Advice would be much appreciated thanks in advance.

It would be worth elimating the glow plugs, battery, starter and main starter motor earth first. On the 2.5 it's easiest to use diagnostics to identify any faulty glow plugs because physical access is a problem. If you are sure the engine cranking speed is perfect try parking with the front downhill or adding a non-return valve as miloslo says. If that helps, it proves only that it is a fuel problem.
