E46 330D parking sensors - One long beep
Discussion
Yesterday evening my parking sensors worked as they should, hooting more frequently as I reversed up the drive towards the car already on there.
Today I was shoe-horning the car into a space up the hill in Clifton, Bristol. The parking sensors just emitted one long beeeeeeeep for about 5 seconds and then stopped working.
I turned the car off, got out, cleaned the sensors with a water bottle and a rag, got back in, turned it back on...
Once again I turned it on, plopped it into reverse and the 5 second beeeep came and then nothing else, regardless of how close I got to the van behind.
Any ideas what could be wrong guys?

Thanks for all th advice.
I have listened to the sensors and all of them tick at the same volume. Furthermore, they work very early in the morning once or twice and then resume the single 5-second hoot followed by not working.
Any ideas as to what it could be now all of the sensors (using the listenig test) seem to be ok?
Would it be prudent to buy one and replace each existing one with the new'un until the faulty one is identified?

Thanks for all this help guys. I have no need to move the car today. I am being a jubilee sloth and fantasising about putting modern, reliable diesel engines into old classic barges. Also been brushing the dog 
and quaffing tes like there is no tomorrow.
The sensors worked beautifully last night both at the beginning (as I reversed towards an Audi A8L and an Evoque) and when I got home (reversing up the hyper steep drive at mine - nicknamed "the lifeboat house" as the drive is like a launch ramp).
kind thanks,

The plot thickens.
The sensors seem to have healed themselves. I cleaned the bugger the other day but paid no special attention to the sensors. I can now describe this problem as sporadic I think.
Will see if it does it again today - usually don't work after a long, warm day (which we are in no danger of experiencing today)or a considerable drive. However after an hour on the road today they were fine.
