Let me know how it goes.
I have learned to park by touch, that's what bumpers are for aren't they?
Well, i fitted them and low and behold, they don't work I have learned to park by touch, that's what bumpers are for aren't they?
Instead of a big long beep, i now get silence. I can hear them clicking. One of the 4 clicks a bit quieter than the others but i cant be arsed buying yet another sensor for £25 on an off-chance it might be this one. Basically, fk it.

Sorry to hear that. Your experience kind of mirrored what I was expecting for myself if I had taken that first step to fixing the problem. I ended up thinking pretty much the same way you ended your post, fk it.Instead of a big long beep, i now get silence. I can hear them clicking.

I had a not too dissimilar experience myself.
I Googled the possible causes and someone mentioned it could be due to moisture on a sensor. They also went on to state that jet-washing the area is a no-no, as this could be damaging the sensors.
How much of this is true, I have no idea, but I stopped jet-washing the area and the problem seemed to figure itself out. I, too, was looking on eBay for replacements, but the standard course of response is that you'll likely be buying a duff one.
Worth a shot at least; I found out mine weren't working when a pillar let me know of it's presence.

Be aware that non BMW sensors do not work.
Seems to be the case.I had the 'one long beep' situation, did the click test. Seemed sensors #1 and #3 weren't working. Got a pair from eBay. Installed today. No more 'long beep', all 4 click...but square root of fk all when it comes to actually beeping in reverse.
Should I buy second hand OEM items instead you think helix402?
Not sure why it's being said that non-BMW sensors don't work as I've never had nay issues with these from this reseller:

Used them on a previous E46 320i and 325i as well as x2 E39 530i's
They're covered with a 2 year warranty too

I buy used gen BMW sensors after all the new aftermarket ones I’ve tried have never worked. I had the 'one long beep' situation, did the click test. Seemed sensors #1 and #3 weren't working.

Dan, did you replace all 4 or just a couple? From what I've read (now!) on the forums it appears all 4 sensors need to be the same for the system to work properly.
In pairs as well as all 4; no issues I've had it though where I've been chasing my tail and one duff sensor (old OEM one) took them all out; at the prices as per the listings, it's worth doing all 4 for peace of mind IMO
