6R Polo starting problems on hot days

Post by georgie »

I'm trying to figure out this problem on my wife's 1.4 polo. Sometimes, when the car parks out in the sun for long periods of time, it will struggle to start at first swing.

It start and has a very low idle (+/- 400rpm) and then cuts out. After a few more attempts it starts as normal.

This has only happened about 3 to 4 times, but now her colleague has the same issue, but hers occurs more frequently, around 2 to 3 times per week. She says her husband used her car for 2 weeks straight and parks underground at work and he never had starting problems. As soon as she parks outside on very hot days then she struggles to start.

Is this a common thing on these cars? What could the heat be affecting?

The car seems to swing fine. Could it be a fueling issue? Why only when parked out in the sun though :???:

Does anyone know where the fuel pump relay sits on these cars?

Found this useful link if anyone else has problems with relays on these cars.

The fuel pump relay seems like a common issue on earlier vivos/polos. Will replace and see if that resolves.
