It's a 2009 Panda 1.2 Dynamic Eco.
The idle speed has always been rather erratic when I turn on the air con, but it seems to be getting worse now.
With the air con off, the idle usually sits about 1200 RPM according to the rev counter. When I turn the air con on, and drive around for a bit, the idle speed becomes wildly erratic. I have seen it drop as low as 800 RPM, and today it went as high as 2200 RPM while sitting at traffic lights with the gearbox in neutral. This speed isn't consistent - it may gradually get faster and faster, then it will suddenly drop down again.
Is this a fault, or just a quirk of the car?
