VW Polo V hotstart problem - matkom15 - 15-06-2019
Hello
I have some problems with polo V 2009 year 1,4 gasoline CGG engine type with hotstart. Everything works well in the winter when it is -10 degree, but now when it is +30 it wont start for long time. I really have to cranking some time the it starts. Even when I drove home and stay it for some minutes even wont start for long time.
Dealer told me they have to reprogram computer, to lower some gasoline when the engine is hot.
Could I do that by kess/ktag ?
Thank you
Regards

If you get a dump from your ECU I'm sure somebody can help you here, sounds like you just need to lower injection at start conditions
