Good morning mates

Maybe injector(s) not spray good. Had one friend with problem like this.

I don't disagree :) But client is crazy !
He even changed whole working engine 1.9 for this problem... and same result.
Also , a diesel man checked them too ,,
So his last choice was ecu ! I heard people saying this EDC15P+ needs 3 different maps to change to make it work ,,, maybe it's that?

Also , it's weird that only when it's very very hot ,,, then i have long crank and engine sound weird! If you spray some fuel ,,, boom it works !

I did only few edc15 with hot start, but for them helped only this mod.
Maybe some more expierenced VAG specialist will help further :)

Yes it is automatic! Ohhh so no hot start ?
I thought it was because NO DTC and same problem as hot start i've seen in the past :)

Then i will redirect him to a better diesel man i guess :/

Did the injector working properly? How many miles on the clock? Usually symptom like this is injector problem.. If its compression issue of the engine then cold start will also have difficult starting..
