i get both of these....related to PSM system?

I have no idea, but did find the following:
The orange. circle with triangle and exclamation point light is for the Porsche Stability Management systems. PSM contains the functions ABS (anti-lock brake system), ASR (anti-slip regulation), MSR (engine drag torque control) and ABD (automatic brake differential), as well as “precharging of the brake system”, and “brake assist”
So the warning light can be for any of the above systems and their components.
The 4wd fault light can be tripping due to a fault in the PSM systems. I would suspect either one of the 4 wheel speed sensors or in the engine drag torque control.
You will need a shop that specializes in Porsche scan all the above systems to determine the area of concern and then do any associated testing needed for the fault codes that they retrieve.
Good luck!

Not sure if the 2009's have it but on my 2016 the A with the circular arrow is the auto start feature. You know that damn feature that turns the engine off when you are at a stop light. I personally hate it. So do you have a corresponding button with the same symbol? Mine is below the shifter in front of the console box. Of course, I'm sure your mechanic would have caught that. Good luck.
Moved to the correct forum. @stelvio1200 - a 2009 doesn't have auto-start-stop. The fault here is in the PSM system, and as was noted above, the most likely failure is one of the speed sensors at one of the wheels. These are a known weak point. Porsche will want $130 each or so for them. The Chinese ones from eBay for $12.99 work just fine (DAMHIK.. I just do..) OP - you'll need a Porsche specific code reader to confirm it's a speed sensor, or a mechanic who has a Porsche specific code reader. A Foxwell NT530 will work.
