Yup, it sounds an alarm, telling you that your engine is now full of metal and in need of a complete rebuild; but your IMS has not yet crapped out, but is also on its deathbed........................

I had an IMS Guardian on mine for one year. The plug portion leaked from the middle where the wires came out. Flat 6 provided a new plug and it also only lasted a year before also leaking. I replaced it with a standard plug and disconnected the electrical portion about 2 years ago. Just yesterday I removed all the electric parts from in the dash and put back the switch blank.

Flat 6 discontinued the Guardian without any fanfare since I think the thing never worked the way it should. Good idea, bad product.

Sound like PHS would be a more apropos name... Porsche Hospice Service

Now you're out a motor plus ~ 5 shackles for the PHS device.
