How to remove the exhaust valve electrical connector RS4 B9.5?

[gav28uk]

I need a bit of help/guidance on how to remove the electrical exhaust valve connector on my Audi RS4 b9.5. Due to the location as it's up above the rear silencer, I'm blind to the connector, so can't see what I am doing. Everything being done by touch! 🤯 For the life of me I can't get the connector off. I can see the grey tab and presume this is the retaining clip...what's the magic trick to get it to release? I've tried pushing the connector in whilst trying to push down on the grey tab, no joy, it won't budge.
Anybody able to help...please?

Here's an image to show you what I mean. Remember I can't see this connector, I'm below it!

OK so I've sorted it! :-) So in case anybody else encounters this issue, my solution was to insert a small flat head screwdriver on the opposite side of the grey tab to "lift" it slightly, this released the lock and allowed my to remove the adapter. Job done :-) See the yellow circle attached.
