N reg vw polo engine cuts out at junctions when headlights are on

does the temp gauge reach the red area? check eng coolant .Over heating could cause eng to cut out so as not to cause more damage check the cooling system.When travelling slowly or at stand still turn heater to max heat and max speed this will cool eng but is only a temporary solution

KEY NOT RECONISED

Tty a temperature sender unit.

The VW specs for oil is way over-hyped.

Use a Brand Name Full Synthetic 10W40 oil and you'll be OK.

could be wiring that shifts loose. is it only under hard cornering? i had a problem with a vw that made a buzzing sound everytime i cornered hard. it turned out that my oil pump wasnt picking up enough oil under cornering becuase a piece of plastic int he sump was missing.

you need to get the car plugged into diagnostic equipment,it could be anything if you live in kent i could vag.com it for you

on the fuel injection rail there's a little round silver vacume thingy put your tumb on it and push whilst some one starts the car. that is if this happends when you start the car and when you try to press the accelerator the car cuts out. i have a '00 polo and this happened me! hopefully this helps.:-)

clean the throttle body out only four bolts hold it on,you will need to reset basic setting afterwards,quite a common fault

you should have your fuel pump checked out-i think its not supplying your engine with enough fuel to run it.
