Hallo to all. I See a lot of requests for Hot Start repair in VAG Group (Audi VW Seat Skoda) vehicles.
It is common know that VAG group 1.9TDI PD engines have typical error. They are starting good in could state, but when the engine temperature is over 80?C the engine is starting very poor. It need some time to start.
The problem is in Coolant temperature dependent injection starting maps. The engine is not injecting any fuel when the coolant temp is high and RPM-s are not high enough.
Second problem is faulty camshaft sensor. The symptoms are the same just when you put modified software in the ECU there is no change, and the car is still staring poor. But this is detectable via diagnosis.
So I think is the best to put all those problems in one place
When you girls are posting your dumps, please give some typical amount of information too.
Fox example:
VW Touran 2004 1.9TDI BXE 105PS EDC16U1
I will try to help, ones at day, and I believe that also the other DK members will love to help with solving your files.
