Hi everyone, I'm new to the forum and this is my first post so I apologise for any discrepancies in advance.
I drive a 51 plate, Polo 9N, 1.2 three-cylinder, AZQ engine code with 120k miles on the clock.
Recently my polo has developed a problem when idling which at first appeared to be intermittent although now has become constant.
normally idling at around 8-900 rpm, the rpm would "dip" to around 500 rpm sounding as if the engine was about to stall, at which point the idle would erratically increase to around 1000-1100 rpm and then stabilise again at the norm. This occurs a couple times a minute.
Also, my clutch is soon to be on the way out and the clutch bearing makes a huge racket, although when I press the clutch down, the noise goes away and the idle "dips" seem to be less frequent, could there be any connection between the two?
Furthermore, I've recently changed the throttle body for another from a scrapy and also bought a new temp sensor as I know that they are a common issue.
Any help would be greatly appreciated.
