Hot starting problems W203 -C270CDI

[Pas]

Hi folks.. first post, but have "lurked" on learned a lot!

Have a w203 C270CDI first reg 03/03. Starting from cold ok, but when hot wont start, turns over ok, but will not even try.
Main dealer diagnostics say injector down and losing pressure when stood.
Being a simple soul, I thought replacement injector and perhaps a seal or two! Wrong! - "Sorry sir... 5 new injectors, new seals, new pipes = £1100.00 plus fitting"
Cant seem to get a definitive why, just that the original set up has now been modified, with originals no longer avaiable.
Anybody with any information care to enlighten me before I part with my wifes next years clothing allowance??

How many miles?
Not sure why they have to replace all 5. And btw the MB price for the injectors is a huge mark up on the price from Bosch direct.
I would get another opinion from a good MB indi.

It seems strange that it will start from cold as that would allow longer for air to leak in.
It needs an injector leakdown test performed.

Battery and starting motor must be in very good shape.
This, 5-cylinder engine need exceptional high revs, before program even starts to spray.
This could be warm engine harm.

Battery and starting motor ...

I was wrong.
If there is enough rail pressure, fuelling starts immediately.
