I'm in the process of purchasing a 2012 Turbo S and not sure if a PPI or DME would be useful with this car being a PDK... I'm having a body shop inspect the car for past paint and accident history but will a PPI be needed since its still under warranty and the will the DME be useful on a PDK?

 

Just a hypothetical.

Previous owner takes car to track. Uses OEM brake fluid.

After several hours at the track, the aluminum heat shield melts and the internals of the calipers fry. Brake fluid squirts around the seals and burns off when it hit the backing plate on the pads. Brake pads are caking and cracking. Rotors are glazing.

Previous owner trades in car. Your car is under warranty, but often times track damage may not be covered. Not sure your dealership would cover this type of damage under warranty, and you won't know about it without doing some sort of inspection.

For the cost of the vehicle, a proper inspection (even under warranty) is helpful.

 

Nice hypothetical.

 

Point taken. PPI will be done and mind as well get the DME readout.

 

DME not needed with PDK. The computer keeps people from doing damage.

An inspection would be good for peace of mind if nothing else. Even with a CPO car - I've seen a car with aftermarket suspension parts and a small dent get CPO'd. Not sure how, but I made the dealer buy it back.

 

i think dealer will cover the damage under warranty since you didn't know about it.

 

So with PDK one can't over rev or mis shift causing engine damage?

 

It's a lot harder to do. But I still wonder what would happen if you're in first gear going down a steep hill and you never shift...

 

Correct. Not even if you try.

 

DME scans tell you much more than over revs. If you are paying for a PPI, get a DME scan or run Durametric. It can give you a hint if the car has been flashed. Also tells you operating hours. You can calculate average speed that the car has been driven by the odometer on the speedometer and the operating hours. It will give you a hint if the odometer has been tampered with or has spent time at a track.

You can also use PIWIS2 to see the date stamp on the memory of the control modules - have they been tampered with.

I think that depends on the dealership. I think there are plenty of members here who have had very good "good faith" repairs, and others that have been taken advantage of due to ignorance.

 

Does the DME log 'Launch Control' activity?

Porsche also will CPO a car that has been in an accident. I've seen multiple cases of this when looking at the PUSA website and searching for cars. I assume they are minor fender benders but you never know without full disclosure.
