Default Another DME Question

Looking at a 991.2 GT3 that has roughly 180, 15 and 10 ignitions in range 1, 2 and 3, respectively. When I look at range 4, it lists only 1 ignition and none beyond this range. It also states the operating time of the range 4 at 580 min. (car has roughly 10k miles and 450 total hours).

Is a single ignition possible? Also, can I interpret that it occurred at roughly 9.6 hrs (588 min / 60), meaning that 440 hrs have elapsed since?

Appreciate any input at all..

Is this car PDK or Manual (been seeing reports like this on even PDK cars posted recently)?

Are you able to post the DME results?

Also what's the story on the car? It's always good to line up the tests (DME, PPI, brake inspection - whatever you're choosing to do) vs. what you're being told by the seller/dealer.

This one is manual.

Agreed, I just haven't yet lined up any additional or independent inspections. Here is the DME supplied by the dealer. It appears to be a clean car but it comes with a cage so I know it's been tracked. I think it's good to see 0 ignitions above range 4, but the range 4 is what concerns me despite it showing as 1 and only 0.6s total over rev time.

Tricky situation.

On the one hand, the number of stage 3 and 4 overrevs is low and it appears it's been a long time since the range 4 at least. On the other, range 4 generally disqualifies cars from CPO so Porsche takes it seriously. Not sure what they'd do with a result like this.

I guess it depends on how risk tolerant you are and what you plan to do with the car. Seems likely this will be an issue when you go to sell it so if you buy you need to factor that in to the price you pay.

Got it. So then the 1 range 4 ignition is not a fluke? Also, I was under the impression that Porsche would CPO a car as long as enough time elapsed since a range 4 event (I've been reading posts stating something like 200 hrs).

So my understanding is that Porsche has been revising the 'rules' as time has passed. In the past, range 3 and 4 were considered OK for CPO, and range 5 and 6 were not. However as of 2020, range 3 and 4 are also considered problematic regardless of how long ago the over revs were, and compression tests and oil tests are required before CPO. On the flip side, range 5 and 6 can now be considered for CPO if the event occurred > 200 hours ago, assuming it passes compression tests and oil tests.

Given that there were 8 in range 3, I don't know how to interpret the 1 in range 4, but my understanding is that each range is in 2000 RPM intervals for the 1st 3 ranges, so probably the over revs were close to the high end of range 3 and the 1 in range 4 might have been a time average assumption, because 9 over revs in 3 = 3 ignition pulses?

It certainly could be.

From what you can see on here there are varying takes on the DME report. Some are ok with it some maybe not. If you can get to a comfort level with the numbers and you plan to keep the car long term it may not matter at all. However, when you do decide to part with the car in the future you will be dealing with this again. Only that time as the seller.

I would say its a no on a fluke, looks like is spiked up and ticked that range 4. I bought an 07TT that had a normal 1s and 2s and then one ignition in some high range like range 7 or something, no 3-6s, that was a fluke and the dealerships had no issue cpoing it. This would be a good question. If they would cpo, would be less worried. Being the market is crazy tight right now, its a seller's market so its really up to you.

Thanks for all of the replies. So it seems this one can go either way. I'm definitely not looking for a car that was outright babied but at the same time, I also want to have the ability to re-sell down the line without much issue, so will have to think it through.
