207 hdi pulley noise

Hi
My 2010 207 1.6hdi (50k) has an occasional chirp that seems to come from the crank pulley area at tick over. I bought a cheap new replacement pulley mail order which I fitted but the noise is still there. To eliminate I removed the aux belt, the noise was still there so I then remove the pulley and started the engine, all quiet.
Question is, either the new pulley is as bad as the original (which doesn’t look bad) or could it be something else, definitely doesn’t do it with the crank pulley off though ?

Just to update, the noise which is more like a tinney vibration is present with the crank pulley off, do suspect it’s timing belt related. Mines the 90 bhp, are any special tool required pin the pump and camshaft, if drill bits what diameter?
Thanks

It’s probably all the pulleys. You can get a timing belt kit that contains all the pulleys too. You’ll find when they’ve been replaced that it will usually sound as new again. I had all mine done with the timing belt and it stopped all the noises.
