Have I got PSM fitted or just the switch?

[starline250]

I pressed the PSM button for the first time today and nothing happened. I would guess that the led on the switch should have lit up but nothing. That makes me wonder if theres a fault or if someone has just fitted a dash with the extra switch, it is connected so it all looks in order. Is there anything else I can check to confirm I have the rest of the required bits fitted?

When you press the PSM Off button, it should light up. An indicator on the cluster gage that says "PSM Off" should light up as well. When you first put the key in the ignition and turn it one click (but don't start car) does the cluster gage light come on? If not you may have a bad bulb on the cluster gage. Also, you can check the Options Sticker to determine if your car came equipped with PSM. Should be Options code M222.

Looks like I've got a switch then! No option code 222.

I've just checked all the options fitted to my car and I can't find what the following are 476, 502 & 584. Anyone know, there not on the 986 option list.

M476 - Porsche Stability Management (PSM)

M502 - are you sure it is 502 and not 509 - Fire Extinguisher?

M584 - Storage Box

Thanks for that, so I have got it fitted then.

I'll have to investigate why its not doing anything when I press the button.Anyone know where I should start?

It looks like 502 to me but I could be wrong.

502 is likely a specific option for your country. An OPC there might know.

Check the PSM fuse and also run a Durtametric or Porsche tester to see if there are any PSM fault codes (generic scanners will not work for this).

Thank you, I found the fuse was blown.
