Re: Is there a knock sensor on the vw polo 02 plate if so...
Hi, the knock sensor should be located under your intake manifold on the front (depends how you take a look at it) of your engine block. Its round and black with a screw in the middle.

check near front bumper for a tiny black sensor somewhere near number plate the sensor seems loose or bad connection on wire ,not 100% sure where sensor sits but pretty sure its a bad connection on plug to sensor as it is a common prob on bmw when sensor loose /bad connection show minus 40deg when its hot outside and display plays up vw polos have same prob
from the exhaust manifold you have a pipe going down to the first box(cat converter),the lambda probe(o2 sensor) is between these two.looks like a tube sticking out the side.
100% sure it shows one of your cylinder compression is weak, please do a compression test to isolate the problem and get the head/pistons checked . This is a known problem with VW/Skoda 1.2 3 cylinder mills..
