2002 525d Touring Rear Center PDC

[Versicarius]

The rear center left parking sensor has gone on my 525d, it is the only one out of all 8 not ticking. Took it to a garage and they were charging £130 for the part + fitting + VAT, so I thought I'd just buy a £10 one off Amazon and do it myself. However I am not sure whether I need the one where the plug is straight or at a 90 degree angle and I would rather not take the entire rear bumper off and use up some new rivets putting it back on just to find out what shape sensor I need, so I was wondering if there was any other way to tell? These are the 2 types of sensors I mean. Thanks.

I would think realoem.com would be a good way to get the info.
