Yet another DME readout
Guys -
Doing due diligence on an 09 TT, still under factory warranty (32 months to go), but DME readout has a few hits in range 4.
Number of ignitions - Range 1 - 19566 - 258.3 h
Number of ignitions - Range 2 - 4948 - 258.3 h
Number of ignitions - Range 3 - 783 - 254.0 h
Number of ignitions - Range 4 - 62 - 245.3 h
Number of ignitions - Range 5 - 0
Number of ignitions - Range 6 - 0
Operating hours counter: 260.1
Looks like it may have been driven hard recently, maybe test drive? Car is loaded and rest of PPI was perfect. Thoughts/concerns/advice appreciated.

The bad thing is that the range 4 incident happened only 15 hours ago however the ignition attempts are only 62.
Porsche centres are instructed that in the event of overrev events in ranges 4 – 6, especially if those happened less than 50 hours ago, to contact the Technical hotline before starting repairs or granting a pre-owned car warranty in order to find out how to proceed and agree on warranty entitlements.
My advice is, clear this issue with them, if you have a warranty that Porsche will not cause you problems with this over rev report in case of a future claim, then proceed.

I agree with the wise moderator.
I am quite surprised that this took place so few hours ago. I do wonder if it was a test drive or a "weekend long" loaner.
What does the dealer have to say about it?
At the end of the day, if you can find a car without such issues, then walk away. Only if this a special color combo or a good price relative to what you are looking for, go ahead with investigating the next step. But if it is a silver car on average price, just walk away, not worth the hassle...
Good luck.

For future reference of rev ranges for 997.1 Turbo together with a classification of the expected engine damage.
Over rev events are documented as follows in the VAL (Vehicle Analysis Log):
Rev range 1: 6,740 -1 ... to 6,940 -1
⇒ Maximum permitted engine speed exceeded; engine damage possible.
Rev range 2: 6,940 -1 ... to 7,140 -1
⇒ Maximum permitted engine speed exceeded; engine damage possible.
Rev range 3: 7,140 -1 ... to 7,340 -1
⇒ Maximum permitted engine speed exceeded; engine damage probable.
Rev range 4: 7,340 -1 ... to 7,840 -1
⇒ Maximum permitted engine speed clearly exceeded; engine damage probable.
Rev range 5: 7,840 -1 ... to 8,940 -1
⇒ Maximum permitted engine speed very clearly exceeded; engine damage very probable.
Rev range 6: over 8,940 -1
⇒ Engine damage has generally occurred.

I agree with your assessment it has been driven hard recently. That's really unfortunate. THe previous owner may have been meticulous yet in the hands of the dealer it appears to have suffered. If you decide against it, you might alert the GM at the dealer why. I might also be wary of taking your new car there for service should it suffer a similar fate.
It could of course happened on a solo test drive. The way I look at it, if I am the GM at the dealer I would like to know either way that this happened to one of my cars so I can track down and 'visit' with the appropiate person.
I am about a year from my search but I think I am not pursuing range 5 cars regardless of warranty.

Thx for the responses - everyone's knowledge on this board is much appreciated. I spoke with two very reputable shops (one a porsche master tech at a dealer) and they said not to worry with so few at range 4. Responses were similar to some of those I reviewed on the GT3 forum:
- We know that if there were any factory issues, we'd be very aware of them by now
- These cars were meant to be driven and the ones that were not babied have better seated rings, less issues, etc. (not trying to start a debate on this last comment - just relaying the message).
Dianic - color and option combo is very hard to find - looked for months (with cash in hand)
JB 911 - Based on my knowledge of current dealer, definitely didn't happen there. I don't want to start assuming what happened since it would only be a guess.
Once again, thank you. I'll make my decision, and depending on outcome, may be posting pics here in the near future.

As 911slow posted:
Rev range 4: 7,340 -1 ... to 7,840 -1
⇒ Maximum permitted engine speed clearly exceeded; engine damage probable.
There is no qualification to the effect that engine damage probable only if overrevs occurred > 15 hours of operating time ago.
The engine has seen significant overev events. There's a reason Porsche detects those and logs them.
I'd give the car a miss.
Sincerely,
Macster.

And to answer someones question, No. PDK will not overrev and will protect the engine first. This is a manual vehicle.
