I have not heard quite that description before. Could be your pads are giving you some sort of wear warning.

The GPS is not associated with that however.

I think we need a better explanation, can you tell us in YOUR launguage and see if we can get a better feel

i start my engine begin to drive and there is some automatic brake on the front wheel (like if the abs activated ) then the abs light on the computer say abs default intervention after that the PSM light go on too

and after that the gps is freeze at the last position before the too light go on

if i stop and restart the engine the gps is ok until the too light come back

all the other fonction of the pcm are ok

tank you for your help

my porsche dealer think it s an abs pcm sensor on a wheel ( after first thinking it was a battery default )

i think he doesn t know

tank you for your help

Your OPC/dealer needs to put a PIWIS tester on the car run diagnostics.

With the symptoms you are having I am sure it will find a fault or two.

Now, it is 2013, and the same problem happens.

So, finally , what did the dealer changed ?

I drive also 2004 cayenne. and it's fine until recently.

After few minutes use, it automatically applys brake when u stop traffic light, and if you press pedal to go, it'll brake u again, and keep u slow, or not moving (the psm light will on, when it auto brake u)
