Where to start. Sorry for the long post!
Hoping someone can give some advice on normal Porsche procedure and also the likely cause of my problem
Picked up our 997.1 on Monday evening and everything seemed well until Wednesday evening.
After filling up with approx. 20litre of fuel, already had half a tank, about 15 miles i had problems with the revs, it would not rev about approx. 4200 rpm... this was followed by the check engine light. I thought maybe it was just a phantom limp home mode due to the heavy rain(wishful thinking). I pulled into to a petrol station switched the car off and restarted it. No check engine light and everything is running smoothly again, then attempt to accelerate and the same thing happens, very noticeable misfire at approx. 4200rpm massive hesitation i let off and the check engine light comes on.
I call the recovery people who advice unless the check engine light is flashing it is OK to drive back home and they will recover the car in the morning. So that is exactly what i do. RAC/Porsche turn up early morning do some checks and tell me i have codes p0300,p0301,p0302,p0303 and that they would recovery it to my local Porsche. Great i think.
Next day i get a call advising the warranty might be void due to an over rev in range 4. Which apparently is a missed shift. I know categorically i have not missed a shift, i let them know that i have hit the limiter on the way up a few times in 2nd gear but not not missed a shift. According to OPC the only way a Range 4 would come up is if i have downshifted into the wrong gear. I 100% know this hasn't happened. I have driven approx. 260 miles since owning the car of which 200 miles have been relatively gentle motorway miles.
So i am really confused at this point, racking my brain trying to remember if this may have happened without me realising. Check through the forums it would appear a range 4-6 would be a noticeable miss shift. I call them back, but they are saying they have spoken to the head tech and he said the data is 100% accurate and that in order to find out if my warranty is valid i would need to pay for compression/leak down test. They cant give me an exactly time it happened only that it happened after the ran the checks before handover??. Fortunately after speaking to the OPC i bought it from, they agreed to cover the cost for this.
They haven't even given me an indication on what the issues are as they are not prepared to do anything until Porsche check the leak-down and over rev. The OPC i bought it from think that the timing may have slipped based on the information i gave over the phone.
Because all of this was done on Friday, they could not get an answer from Porsche UK. I assume it will be Monday/Tuesday.
My questions are;
How reliable is the over rev data and how do i know it wasn't done before i collected the car? I know that it went to be 'detailed' before i collected it.
With the fact the car runs perfectly fine under 4200rpm, could it simply be a sensor issue cam/air etc?
Has anyone had a similar issue?
How likely is it porsche will refuse a warranty on a car that has been run for 260 miles since purchased from OPC?
The car is OPC bought with 2 years warranty, 45k miles, 55 plate.
