Passat B5FL 1.9TDI AVF EDC15P Hot start fix

[Cjnek]

Hi,
I would like to ask if there is a possibility to increase even more the fuel for the start?
The car has a starting problem as it is warm. Can you increase the amount of fuel even more?

Still problem with hot start.
Firstly it was problem with receding fuel (problem with cold start - air of the fuel system).
Vacuum pump was replaced and now when engine is cold car start perfectly, when its warm - dramatic.

Coolant temp sensor - checked
Installed return valve on fuel hose.
IQ correction on a particular cylinder Group 013: -0,28mg -0,16mg 0,89mg -0,42mg - OK
BIP: 35 -5 25 6 (the first cylinder is a bit out of hand)
The pump in the tank - audible
Seals on injectors replaced 1year ago (no more fuel in oil)
Fuel filter - changed
Synchro angle (on vcds) - 1.7-2.2KW in the norm, though it could have been better

Any ideas?
Regards
