One more time.

1. Downshift is the incorrect term - you are getting more confused as this thread continues
2. RPM limiter has nothing to do with this - you really need to go to a driving school

 

Are you sure your friend didn't mis-shift it entering the freeway? Accelerate hard on the ramp, shift from 3rd to 2nd or from 2nd to 1st when he meant to upshift?

 

Is it possible to over rev a PDK? Will the transmission always shift below the rev limit? Or will the Rev limited always protect and when would this occur or not?

 

[quote=liquidrpm;3419772] I started this thread because I drove my car rarely and babied it when I drove it, and I am upset I've only driven my car 11,000 miles since I purchased it in 2008 and am told I have to pay $20,000 to repair damage done to the engine.


This Thread is a load of ____. The portion of the quote above says it all: we all own these cars as soon as their off the lot. The pcar ran well at some point therefore the OP's responsibility is clear.

Who else should pay ? You break you pay is what I've always been told.

 

You're welcome, and looking at those quotes, I would definitely go for the pulley first, if only to give the shop a chance to look at things more closely.

To the OP.... I think you have to assume that someone over revved the engine if the Porsche system produces that information in a read-out. No way will you remember all the driving and all the shifting you and your friend - drivers did. Accept that as the bottom line and move forward. You have been given some first-class advice in this thread... go and work on it and hope for the best. Keep us posted.

 

Read the entire post and in trying to stay objective, I must say that it is hard to argue DME recording of the RPM data. I do not believe that an argument of how gentle the car has been driven is sufficient to negate what the data is telling. It is also hard to believe that there would be a conspiracy plot by the dealer to alter the data in order to avoid telling Porsche the true reason for failure.

As evidence is showing the car was over revved hard. Whether it was under your operation or your friend’s the facts are what they are. Letting a friend borrow a MT car is always a gamble. I only let my very close friends drive my S, and they baby it more than I do, plus they all had MT vehicles before so I am very familiar with their driving habits.

It would be very sad if it was someone else who intentionally or not abused your vehicle when you took so much care and effort to drive it gently, but you wouldn’t be the first person I heard this happening to. Some people will just jump into a sports car and think they are a race car driver without having any such knowledge or experience. As clearly shown, it only takes one mistake to cause serious damage. Good luck to you as I’m sure this can’t be easy to deal with.

 

Wow, can't believe the thread's not locked yet! So, under the 30 buys Porsche and only drives Grandma to church. Let's "friend" drive it often, so it appears. Friend is driving it while car dies. Tries to dispute serious overrevs recorded on DME that can't possibly lie - revs done during his ownership. Admits he doesn't do all the driving. Band aid the crank, trade it on a Toyota and hope for the best. I traded my P car at a BMW dealership and they metered the paint, but they certainly didn't run the DME. They will run a Carfax though, so better dump it quick before the record goes on there.
This was an entertaining thread.

Someone thinks the rev limiter will protect you from overreving the engine needs to buy an automatic. Any manual can be "money shifted".

 

Thanks for posting the worst DME I've ever seen posted. The motor is toasted right after not one over rev event, but two. Since the time wasn't the same up the entire range, looks like two separate very recent events. Even if the car was running, no one would buy it if they ever pulled the DME.

 

1. This thread should not be locked. In fact it would be criminal to close it.
Its by far the most interesting thread since I've been on this forum.

2. To the OP. I want to believe you, you certainly sound rational. But, you can understand why you are in this situation. No matter what you say, you pretty much can't win this one. The report speaks for itself (fake or real)

3. If you are 100% convinced that you did not cause this damage, I would fix the pulley, and then trade the car at a different Porsche dealership. That's assuming they would not pull the report. If I was convinced that was Porsche's fault, I would not feel remorseful or like a dirt-bag by giving them back what I would consider a POS.

Good Luck.

 

Man I this all has been an interesting read, actually quite comical...

Sorry liquid when you write about your driving style and what your personal style is like I develope a mental picture of you in my mind. You seem like you know less about cars than your average chick...

My opinion as a person that knows engines very well is; if you turned it off very quickly after the temp alarm went off I would do just the crank fix and see what you end up with... Potential to save you thousands for only the cost of maybe a couple grand more.

Even if it does turn out OK you just never know the long term effects. If you do not end up having to replace the motor I would sell it soon.

 

Lots doesnt add up:

12000 miles in 3 years is 4000/year. You stated much less driven per yer.

You say you don't know how to downshift. That could be source of error simply because you don't know what you are doing. You have driven 100000 miles on MT but don't ever downshift? What?

Likely missed up shift. You might not have known.

How long ago did your bud drive the car without you? Do the math. Maybe he beat the **** out of it. But in the end SOMEONE beat it again very recently. So either you did them both, your bud did one and you did one or someone drives your car without you knowing. End result is, DME shows over revs and it is your car. You lose.

You can't expect the dealer to somehow side with you and not side with the DME. How many times do you think that someone told them they did not mis shift when faced with a 20k repair? You might not have but someone did and it's your car. So you eat it in the end.

Sorry for your inevitable expenses. PEACE.

 

Nope... well, maybe if you punch it while in neutral...

PDK won't let you manually downshift into a lower gear if it would cause the engine to overrev. Your car will just ignore your "downshift" command.

 

liquidrpm,

Is there any chance you could edit this with something on the order of a readers digest version of where this stands today? It might be worthwhile including it at the bottom of your first post.

 

I'm no expert but is this even possible? My speed at 5,000 rpm while in first gear is 30 mph. That means you would have to jam it from a higher gear into first gear at almost 60 mph.
