N80 Purge Valve location?
- Thread starter Dannheath
- Start date
that’s all the hope i need,
i’ve spend so much already replacing the fuel pump, fuel filter, starter
So, why don't you locate the engine coolant temperature sensor and replace it with a genuine new VW Group one.
very weird
note that the first start after replacing is still normal to fail as the previous valve let gasoline vapour inside the intake manifold with engine not running making the fuel mixture too rich, but not after that
have you seen this sensor causing starting problems in this engine?
The engine coolant temperature sensor output is used to set or influence the engine starting mixture, so if that reads a low and wrong temperature, then the engine will be getting supplied with too much fuel while being started, that can cause starting problems - the same can happen if this sensor is reading a really high temperature when the outside ambient temperature is a lot lower.
I think that it is still true that even now, the "fly by wire" accelerator pedal position sensor, when Full Open Throttle position is detected, will, when the engine is not yet running, shut down fuelling and so that allows fresh air to be drawn through the engine and so eventually allow a "flooded" engine, to start.
