VCDS/VAGCom help in berkshire

hi

could anyone help, i have a 1.9tdi 2001 octarvia (ALH engine) with 200.000 miles on the clock.

I have a big problem with cold starting which takes 30s to start with the engine cranking over and pumping out lots of white smoke.

its not lossing coolent,

Once the car has started then it will start on the button all day long.

i have tryed cleaning the ERG valve, replaced glow plugs, replaced glowplug relay, checked glowplug power , replaced CTS (coolent temp sensor) , replaced MAF sensor , turbo was striped and cleaned (sticking turbo vains).

The cambelt was changed about 10000 miles ago but it was done by a vw chap that only timmed the pump to the timming marks, i have had someone tell me that i need to get fuel pump timming checked on a computer to see if it not retarded.

cheers
