Help needed, fast. My brother is close to completing a deal on a really nice C2S and has just received the following DME Range Report. The car is perfect, all records, 16K miles and comes (from a Porsche dealer) with a full 2 year, up to 100K CPO warranty.

Here are the details:

Total hours as of 10/29/13: 443,8h

Range 1 Overspeed Op Hours: 344.5h, # of Ignitions >max: 7157
Range 2 Overspeed Op Hours: 288.7h, # of Ignitions >max: 1625
Range 3 Overspeed Op Hours: 288.7h, # of Ignitions >max: 271
Range 4 Overspeed Op Hours: 288.7h, # of Ignitions >max: 178
Range 5 Overspeed Op Hours: 288.7h, # of Ignitions >max: 125
Range 6 Overspeed Op Hours: 0.000h, # of Ignitions >max: 0

As can be seen it has 1 occurrence that took it into ranges 2-5 at 288 hours. That is almost 200 hours ago. He and i have 2 questions.

First, how concerning is this report as to the health of the engine, and its prospects for long life, and, secondly, would the presence of these revs impact any future claim for engine work even though the car was inspected and certified for CPO with these revs already in its history.

What assurance (other than trust me) can he receive from the dealer or PCNA that this report (absent any future over revs past Range 3) would not have an adverse effect on future engine claims during the term of the CPO warranty.

Any and all response and guidance based on actual experience would be MUCH appreciated. TIA from both Frank and me.

 

well it s CPO d even with the over revs... so Porsche owns that...
There are two camps. 1. stay away from the car 2. they are OK with that DME, like you said , it was awhile ago. A major failure would be most likely have occurred at the time of the over revs..
6 spd or auto?
Ft Meyers Porsche by any chance?

 

I don't think the dealer nor PCNA would go as far as giving a written "assurance" or guarantee that they won't be biased in the future should something catastrophic happen with the car. I'm just really conservative when it comes to "trusting" car dealers.

All that being said, it does look like it was one missed shift (betting this is a 6sp). I'm the risk averse type when it comes to expensive luxury items. So I'd be in the camp of passing on any car that has any overrevs range 4 or higher.

 

Does anyone have a definition of these ranges?

look thru this.

 

Thanks guys for the feedback so far. He is on travel till this evening and wants to decide (and consumate) by the end of month. But, caution is the byword on something this binary. And yes it is a 6 speed MT.

Here is a copy of the range values for various DME Porsches. Range 5 goes up to 9500 rpm.



Three (3) ignitions are equal to one crankhaft revolution.

 

On another thought, SZVGT3, you must track your car a lot, yes? What does your DME look like? If you had 4-5 overrevs, bet you don't worry much about it if your car has been fine the whole time.

 

Scoper, yes I have done many DE's and Club Races in a variety of fine P-Cars from a 69 911S 2.2L, to 73 RS, to 92 Cup Car to a 2004 GT3. That said, I have never suffered a serious over rev and have NEVER had the misfortune of a full clutch release (or anything close) on a destructive downshift or misplaced upshift. Either lucky or good; I'll go for a little of both.

The car in my sig and avatar is brand new to me (2 weeks) and has no events in Ranges 4-6 and only 13 ignitions in Range 3 from its previous owners. I am aware of PCNA's focus on the DME events and don't want my brother to get caught short during his ownership or in an eventual re-sale after warranty.

So I guess my answer is that on my vehicles where I know my habits (and faults), it is a bit less of a concern, than on an unknown car where the total history is not as well known.

 

I'm new to pcars and as a new used car buyer I'll add some comment in the arena I know namely buying used cars from dealers. That DME report would be a show stopper. There are many good pcars for sale from many sources. If peace of mind is something this report would comprimise than walk away.

 

Maybe...maybe not. The car is CPO'd by the dealership but PCNA surely has a say in big warranty claims such as an IMS failure. As I recall it there was a thread some years ago either here or on Rennlist about an engine replacement on a CPO car that was refused by PCNA. The argument was that the car should never have been CPO'd in the first place due to its history and the dealership had to bear the cost of the engine replacement for certifying what shouldn't have been certified. The dealership of course had a different opinion and you can probably guess what ensued.

 

PCNA advertises CPO warrenty as the same level as the new car warrenty.
So I think you are right in a way because PCNA can deny a claim on a new car too.

On behalf of brother Frank and me, a big THANKS to all who responded here. Frank has made his decision and he is going to pass. Car, dealer, dialog was all on the up and up, but he just didn't feel compelled to go for this particular one at this time.

He'd be giving up a gorgeous 2008 Special Edition (1 of 250) Boxster S (GT3 orange/black) in flawless shape with 8K miles, plus a wad of cash and just felt he needed to pass.

So, the search for the "right" 997 Coupe continues. He is looking at 2006+ C2S or C4S, 6spd, with almost "mandatory" options of PASM, Sport Chrono, sports seats, AeroKit, and PSE. Any leads are appreciated!

 

Just saw a 6speed member yesterday thinking of putting his low mileage C4s with x-51 pwr kit up for sale. I'd be all over that one.

White Rock, they are both great cars. He has already looked at the east coast car, and i"m pushing him to "go west". We'll see what happens.

Thanks for the lead, keep 'em coming.
