Warning message with error codes...

[pontypool]

My 2003 Cayenne Turbo has just started giving me messages on the dash for PSM and Air Suspension and having read the codes got these:

1425 Pressure sensor (brakes)

1316 PSM Control Module

What do these two actually mean as the air suspension seems to work perfectly going up and down on the switch without a problem?

Thanks

Thanks for the link but the two codes on my print-out don't seem to appear in the list :(
