Hi there I am a new member and looking for some help with my partners automatic Polo.
The car will start from cold but will cut out after a few yards if you come to a stop, it is ok if you sit and let it idle for a couple of minutes and once warm is fine.
We have had a new water pump, cylinder head gasket, HT leads, distributor and cap, new plugs,oil and air filters, new fan assembly,battery, thermostat throttle control body, temp control sensor and the sensor that tells it how much fuel to give when cold.
The other odd thing is if you drive for say more than ten miles and turn the heater to cold then the temp gauge starts to rise but turn it to halfway it goes back down if you come to a stop the temp gauge it will also go back down to halfway point

I would welcome any advice as it is becoming frustrating.
