will leave this one short and sweet. Shes a 2001 face lift 2.5 ts with the bmw engine. 70k miles. She'd sat up for a year before i got it but its done over 2000 miles now. Had a good service, oils, fuel filter, air filter, battery. Anyways on a chilli morning its still a tad hard to start and requires turning ignition on and off a few times then a 10 second grind to get her started and then a nice white cloud of smoke but generally after initial start, and 5 seconds of smoke and chugging its returns to normal and is really driveable There is no management lights on. Anyway im putting new glow plugs in it in the morning along with a refurbed inlet manifold(sand balsted + painted).
Is there anything ive missed? Diesels are alien to me, v6 petrols are more my thing, could it be the diesel verson of the dis/ distributer to blame? or what is it i've missed? most diesel omegas seem to eventually give bother with hot and cold starts my motor has only 70k miles and i want it to start like a brand spank new car.

Glow plugs been changed ?
-
Change the glow plugs (as you have said) and whilst in the engine bay, check/replace the leak off pipes (although they aren't causing this issue). That should see you right :y
-
Glow plugs are the obvious thing to replace in the first instance.
The lift pump if also problematic on these, but generally only problematic if tank is below a quarter...

As said Glow Plugs, you only need to lose a couple and it becomes problematic on cold mornings, also worth checking the GP Relay is doing its job as they can cause issues.
Check voltage out of the Relay, six thicker black wires on top of it feeding each plug, should see +12v still there for a few seconds after the GP Dash light goes out, you can also diss the top plug of the relay connector and measure the resistance of each Glow Plug in turn should be about 1-2 Ohms each. They normally go open circuit if faulty and / or the connector on top of the GP gets cooked.
