Dreaded Rev Ranges

[nickd01]

I had my car appraised by a dealer today, and they plugged in the gadget that reads rev ranges.

Basically, it had 65,000+ rev ranges in zone 1 and a lot in the other zones (I didn't see what) I think they said it has a few in the higher range (5 I think) but that happened 800 hours ago. Basically it's been thrashed and they refused to bid on it - disappointing but fair enough.

I don't rag my car, it sits idle during the week and when it's used it's often with the family so traffic light GP's are out! I've had it five years, never tracked etc. etc.

Either way, is there any chance the readings are wrong? It used to be a warrantied car by Porsche (over 3 years ago now) and 9Excellence did a compression test a couple of years ago an it was fine. I only do about 4,000 miles a year.

I'm just a bit concerned as I really try and take care of it and want to sell it 'in good faith' to whoever it is.

It needs a service, so I'll get a printout of the readings from whoever does the service, but I just want to understand how significant this all might be.

Thanks

Thanks, I'll get the readings and go from there.

Tom,

I know you don't talk rubbish so it is a given that is retracted given the new information.

Talk soon.

Apologies Ken - my initial post wasn't very clear leading you to your statement about the dealer. Didn't mean to mislead - I should have written something like "There were quite a few readings in the higher rev ranges (Range 5 I believe) that happened 800 hours ago"

Either way, I wasn't clear. Sorry.

In the interests of transparency it was ourselves, 911virgin, that looked at the car. Nick and I met briefly, a colleague inspected the car and discussed his findings and the ECU report with me before we made the decision that the car was probably not for us. I would agree with Ken in suggesting that the maxed out ignitions in RR1 are not reason enough to reject a car. They give a feel for how the car has been driven but given the limiter is set to prevent damage being done, in the eyes of the manufacturer a car with 65556 ignitions recorded at the limiter is seen to have been driven within tolerance despite this representing more than 3 minutes of accumulated red line activity. Had the data logger recorded 5 ignitions in RR2 (missed gear down change) I would consider it to be erroneous. Assuming we were happy with everything else this would not necessarily prevent us from buying the car. In this instance, however, the RR 2 activity was closer to 500 ignitions representing a genuine over rev event of some significance. If required I'm more than happy to explain why this prevents our acquisition of a car and of course more than happy to provide advise and further interpretation if required.
Sorry we weren't able to buy the car Nick. I appreciate you making the effort to bring it to us.

No worries at all Tom; as you say you can only go on what the tester is showing you and you do have a duty of care to your customers on both sides. As I mentioned, the readings really surprised me so I'd simply like to understand the significance of them a bit better to decide what the best thing to do with the car is if I did want to continue trying to sell it.
