Sounds more like the PSE pump.
What model/year is it?

Hi GH
Not sure if the R171 has the same issues with water getting into the PSE pump in the boot - the R170 certainly does - this CAN be dried out.
Worth doing a google search to see if the R171 suffers the same problem.

If you mean the alarm as in bad guys breaking into the car, the problem is most likely the siren unit. Common fault as the onboard battery fails. It's behind the wheel arch liner. Locate & remove/replace (about £80 from dealer) and nothing to do with PSE pump (can't see how/where that fits into your original post)

On the R230 SL it's behind the front liner on the nearside, but may be different on yours. Let it go off & listen for it!

To get the liner off isn't hard - jack it up, wheel off, there is a succession of screws, bolts & clips - all pretty obvious.

The siren unit is round, about 10cm in diameter - wiring unclips. You might be best to disconnect only & if the symptoms go away, get a new unit (plug & play) then do the swap - just in case it's something else.
