Does anyone know how to reliably trigger PSM? Need to reproduce a fault for warranty

[jfoxny]

I have a problem with my 06 997.1. The PSM control module is faulty. When PSM is activated, by hitting a large bump at speed for example, the car throws a fault. However, when you restart the car, the fault clears. I was able to reproduce the fault and have the dealership scan it while the car was running and they clearly saw that the PSM control module was bad. I have a Platinum (the best - $4000k) Fidelity warranty on the car so I figured, no sweat, they'll cover it for sure. Turns out nothing is ever that simple.

The warranty company will not cover the claim unless THEY can reproduce it. They drove the car for seven miles but the fault did not show up - probably because they were driving on smooth roads. I can reliably get the fault to throw on my drive to work everyday since the road is bad. It seems that the fault only throws when PSM is activated. So now I have to figure out how to reproduce the problem reliably, tell a tech (because they won't test drive it with me - only with a tech) and hope the tech can reproduce the issue with the adjuster in the car.

Does anyone know how to reliably activate PSM so these dopes can see the fault in action? Are there any tricks?

There is a set of railroad tracks near the dealership and I'm thinking if you hit those at speed it should trigger PSM. Going to try that today after I pick-up the car.

Thanks,

Just got back from the dealer and have a little more info. about the fault. Here are the codes that were thrown:

Control Unit, Priority, Fault memo, Status, Description
PSM, 1, C101, ACTIVE, Control unit faulty (No fault symptom available)
PSM, 1, C150, ACTIVE, Communication DME control unit (drive) (No fault symptom available)
PSM, 1, C153, ACTIVE, Communication steering wheel electronics unit (drive) (No fault symptom available)
SEAT MEMORY, 1, C152, ACTIVE, Communication PSM control unit (drive)
DRIVER'S DOOR, 1, C174, PASSIVE, Fault, convertible top control unit (comfort) (Signal implausible)
PASSENGER'S DOOR, 5, C174, PASSIVE, Fault, convertible top control unit (comfort) (Signal implausible)

And the part that needs to be replaced is the AS ABS Hydraulic Unit Pump (997-355-955-06). Does this give anyone any ideas on how to reproduce?

Fault happened on start-up today. So, I guess it's not thrown just when PSM is triggered. Strange.
