I pull off and it sounds like somethings in the passengers side door/rear passengers door, it "pops"......

Anyone got any idea why?

I had a creak from this area not so long ago, sometimes I suppose you could say it was a 'popping' sound.

Get a passenger to hold the passenger door open slightly when you're 'pulling off' (oooh matron), and if that stops the noise, you might need to adjust the door striker slightly.

Cheers for the reply, will try that with my mate tommorow.

How do I adjust the door striker though? What even is that?

Yep, the noise disappears when doors open!

Does anyone know how to adjust the door strikers?

Bump as I would also like to know!

On the b pillar there's the latch the door closes on. You can adjust that a few mm up down and side to side
