Faulty parking sensor solution.

Thought this may help a few members who have a faulty PDC sensor. No guarantees it'll work for everyone but did for me.
Car came back from the garage this week after some work and they had given it a thorough clean which it needed. Unfortunately from previous experience I know how power washing can have a detrimental effect on the PDC sensors. I remember having to have at least one replaced on a couple of my old ones and they were about £240 fitted from BMW so no small change for a simple part.
On selecting reverse the very long beep, turn engine off keep it in reverse and check the ticking/clicking of the sensors. My right central rear sensor was not ticking, no signs of life. I was almost certain this is due to water ingress from being washed at the garage.
Got my Dewalt hot air gun, high speed air and 120 degree setting. Kept it about 4 inches away from the sensor and dried it thoroughly for 2 mins checking the surrounding was only getting warm.
Check for clicking again and we have signs of life! Clicking like all the other ones. However when I select reverse still a long beep.
Plugged in the diagnostic cable with INPA and "short circuit PDC sensor/sporadic", erase memory and all is well. PDC working as well as previously.
Before you fork out for new sensors, might be an easy 15 minute fix for someone.
