Rattle with air con

[mph999]

Hey Guys,

Any ideas on this ... (2008 1.8 MK3)

Intermittent, but with the air con, there is a rattle, almost sounds a bit like a diesel. Noise disappears as the compressor kicks in and out.

It's most noticeable if you listen low down just behind the drivers side front wheel.

I've had a stethoscope on :

Alternator
Tensioner
Idle pully
Powersteering pump
Water pump
Compressor
Engine Block
Exhaust

Nothing noticeable on any of these - even when it's not doing it I'd have expected one of these to be a bit noisy

Vid shows issue best example about 20 sec in, compressor kicks in at 23 sec

Thanks in advance
