Hello
I have an 1996 Passat TDI 90 Hp, Euru-spec.
The engine is chipped to 115 Hp(Wetterauer)
The car has done 160" Km`s without any hiccup`s,60" of them after chipping, but lately it has a habit of stopping after startup, especially in wet weather.
This is very annoying, often it takes 5-10 startups before the engine idles without stopping.
There hiccup is most prone to happen if the engine has not reached full operating temperature.
It has never stopped during driving, only during startup.
Changed the fuel filter yesterday, without any difference.
Any suggestions?
