Hi all,

I am trying to replace the pressure converters on my 535d. Can anyone please give me some advice on undoing the electrical connectors? They have a black tab and a white clip. I've pushed the black tab down and got the white tab to click into it, which has slightly loosened it but not enough to release it.

I managed to somehow get one undone but I'm stuck undoing one.

Thanks,
Tom
