Warranty and Rev Range

Just had an extended warranty renewal rejected because of a RR4.

It so say happened 40 hrs ago but I have no recollection of this happening and I think I would probably have remembered this.

What I want to know is can I work out how many miles ago this was?....... Is it as simple as average speed on car's computer x 40 ?

Thanks.
 
Your suggestion is a good rule of thumb but depending on your mileage you might be able to recall 40 hours back.

Do you have a manual gearbox?

Your wording suggests only one overrev, is that right?

I was told I had some overrevs 76 hours previously and when I checked I found they were AT 76 hours (out of 350 total operating hours). If they have not given you the print-out you should have them provide it in case they have made the same error. The point being that they normally disregard overrevs more than 200 hours ago.
 
Hi Ralph,

Yes the car is manual and there was I think one occurrence.

Have not yet got the printout, but I will.

The next dilemma is do I pay for all the oil and leak tests on top of the cost of the warranty ?
 
Range 4 is 7400-7900. As an over rev is counted as one spark in that range I would have thought it impossible to have just one?
 
A related question I have been wondering about if that's ok? I have a 997 GTS PDK can I over rev that say by clicking down too many gears in manual mode by accident ? I would expect the software to reject the downshift (an audi DSG box does but that and will shift up at rev max which the PDK won't I.e. It overrides manual to prevent damage) Anyone know ? Thanks Rob
 
Hi Rob,
PDK won't let you downshift to out-of-range engine revs so you're safe.
For the same reason, Porsche have requested PC's ignore any recorded PDK over-revs.

Regards,

Clive.
 
Clive,

But PDK will allow the engine to overrev whilst in manual control, if you don't change up before the limiter. You get a "stuttering" from the engine - I know this from the time the Goodwood Chief Instructor took my GTS out to show me best lines and came out of the chicane and was late getting into third.

The disregard as I last understood it (in writing) was up to a few Range 3, which Porsche regard as artifacts of the software.

Surely the stuttering is the engine cut out to prevent over revs on the upshifts and the software will not allow the change down on the downshifts unless it is within the rev range, hence the fact that you 'can't' over rev a pdk.
 
Peter,

I think it is a soft ignition cut-out that does not cut out exactly at just below Range 1 lower rev point. My PDK GTS had over revs in 1, 2 and 3.

I can exactly relate an increase in the overrevs to the Goodwood incident I reported as I connect a Durametric tester after every track day and log the results, sad I know but...
 
Had my GTS checked for over revs as 6 months old when I bought from OPC it's PDK- and it has band 1 and 2 over revs at that time that OPC were happy to dismiss as previous posts
I do wonder about the max band on a PDK as I once foolishly tried launch control in manual rather than SA and missed the change up from 1st- the needle went around a rather long way[&o] and I 'be not been brave enough to have another check done
As an aside when I traded in my manual carrera S for the GTS from the OPC I bought it from they told me the S had had a band 4 but the hours showed that was before I bought it - I had run that car for2 years with a full approved warranty.

Interesting point, be interesting to see what comes up when mine is tested [:eek:]
 
Thanks for info re PDK somewhat reassuring but sounds like it's still possible to over rev in some ranges. Bought mine from an OPC with a two year warranty - asked about over revs and they said they didn't bother to check PDK cars. Maybe I should have insisted :)
 
Bet they will check if you want extended warranty...

I sold my GTS with overrevs and a lot of track miles on centre locks and no questions or issues on either - I sold it just before it fell outside its 3 year warranty. On its replacement Cayman, I got an overrevs report, 111 point check record (useless really if you see what they check), geo report and full spec down to id numbers of all modules and commissioning dates. Having said that one can worry too much but for me it is better to know up front than find out afterwards. I bought the GTS blind (not from my excellent local OPC) and discovered stuff later which somewhat soured the experience of a really great car.
 
Yes I bet they will! Hopefully will be ok though if I decide to extend - year and a half left to decide.

 
One of my PDK cars is all clear, but the other has range 1 & 2 overrevs. They are not the ones that cause problems though.
 
This is the over revs data I received today.

Think I would of known hitting RR5 in the last 40hrs. Total shock to me !!!

See what you make of it.

Showed someone who said it doesn't look right.

Range 1 398
Range 2 56
Range 3 11
Range 4 11
Range 5 3
Range 6 0

It's not possible to "over-rev" the engine with PDK transmission as the ECU is programmed to prevent it. Secondary protection is also offered in the form of a built rev limiter that cuts ignition. This is the stuttering noise you have heard.

Centres have been advised to ignore any over-range rev reports as these are not significant in the context of engine condition.

Regards,

Clive.
