Hi.
I hope I'm not insulting you and I may be being stupid here, but aren't they supposed to turn off when the engine starts? Does it work at any time? Mine only works with the ignition on and the engine off.
Bad news through- I changed the sensor on mine last year- on a A610 its fan belt off, A/c compressor loosened, work in cramped conditions job- and you'll need a very small, thin open ended spanner as it is so close to the block that the access is very limited and ring spanners and sockets cannot fit.
Lastly don't make my mistake- the bolts holding the A/C compressor are slightly different lengths, get it wrong and it will rub through the insulation on the oil pressure switch and give you an intermittant oil pressure warning (in my case after 10 miles of driving when the bolt heated up). Took ages to find that.
Have fun!
