This car has had bad starting for some months now seems to be getting worse,when engine hot or cold needs cranking for an age before starting but seems to run fine after that.Only code present is p1570 ecu blocked which i do not think significant.I have had experience with leak checking ordinary common rail injectors can you do any leak off checks with the pd engine?
apparently you can buy seal kits for the injectors from audi but i am wondering what is involved in removing and reffiting injectors?
Any help with this one much appreciated.

Found this in data

idle smooth running valve inj quantity-
cyl 1 mg/s 0.52
cyl 2 mg/s-0.65
cyl 3 mg/s 0.07
is that minus figure on cyl 2 significant?

thanks
graham.
