I hate my pig but I love my pig, can anyone please help me before I send it for scrap. Over the space of the last 4 years of ownership my car has been in the Porsche dealers for 2 years in total with suspension problems, to cut a long story short this is now sorted and was due to a faulty replacement air bag being fitted. Moving on after 3 months of (almost) trouble free motoring this is what’s happening now and would love some advice as the closest porsche dealers is over 200 miles away from me.
When I picked up the car from Porsche it ran out of petrol before I got to the garage at the end of the road and although I filled it up it the engine warning light remained on I assumed this was just fuel related and drove home with it on and reset it when I got home.
Wind on a few weeks and the engine light came back on and gave me a camshaft position sensor error p0016 so I sent the car to my local Porsche mechanic who changed out the sensor and did a full service on the car including plugs filter oil etc etc. All this time the car has been running fine but as I wanted the sensor light out it was changed. However after changing it out the light came back on almost straight away. The car has been a bit sluggish to start sometimes and sometimes on pulling away from a stop has also been hesitant.
This was about 3-4 weeks ago and now it is worse again, at tickover it’s noisy, it doesn’t like acceleration and is running really rough although if you are going over 50mph it doesn’t have a problem and seems to run fine. The EML is now flashing rather than being a solid light. I attach a video of it running.
Any thoughts would be a help before I decide to get it hauled back across again

Hi Guys, I am a proud owner of a 2010 Porsche Cayenne Base model and I have been having a intermittent Engine hesitation issue. the following is a detailed issue of whats been happening, any suggestions that would help resolve this is appreciated.
About a month ago I was coming back from Roosevelt lake ,AZ which is about 3 hours from Tucson, it was a hot day 113deg, I was already in town and the gas gauge read about 1/8 of a tank and I was starting to move from a light when all of the sudden it felt like the engine stalled and came back on for a second then it did it again and my CEL came on.
I thought maybe my gauge was off and i was running out of fuel so i found the nearest gas station and filled up, I drove home and connected my car to my Icarsoft Computer and it was showing error P2293 Rail Pressure Control, I cleared the error and decided I would drive the car and see if it would happened again, Two months and hundreds of miles of mixed city and highway driving went by without a hitch.
Last week I had to go to LA so I packed up the car (4 passengers and luggage) and headed out. About two hours in on I8 right before Yuma it was 114 degrees outside and I was cruising at about 85 MPH, the gas gauge read about 5/8 of a tank all oil and coolant temps were normal when all of the sudden the hesitation came back, it would run normal then hiccup then run normal, ect.. and the CEL came back on, this went on for about 20 minutes but I was still able to maintain 80-85 MPH.
After 20 minutes of this we decided to pull into a gas station and fill the tank with gas to see if anything would change and wouldn't you know that after filling up and setting off again over the mountain pass towards San Diego the car ran without a hitch, we averaged 77 MPH all the way to LA, but we would stop to fill up whenever the gauge read 5/8. after a couple of hours the CEL turned off on its own.
On our way back to Tucson we decided to fill up in San Diego and not fill up until it started to act up, and to my surprise the car once more ran flawlessly.
We didn't fill up until the gas low warning chime came on in Marana, AZ. The highest temperature this day was 104 deg. We filled the tank and made it home without incident. The next day I connected my car to my Icarsoft computer and it was showing the following error codes: P2293 Rail Pressure control, P0300 Random/multiple cylinder misfire detected, P0301 cylinder 1 misfire detected, P0303 cylinder 3 misfire detected.
Could this be ambient temperature related? Vapor lock at high ambient temps? If it was the fuel pumps you think it would have failed again on the way back, right?
This has to be happening to other people with 2007-2010 Cayenne Base models. Any input will help.
Thanks in Advance.
I’m having a weird ‘fuel thing’ with my 2001 Porsche 911… So, I’ve been thinking it gets terrible gas mileage, compared to my 986 Boxster. I expected slightly less, but, it seems pretty bad. Now, I can’t help but wonder if there’s actually something amiss about it.
When I fill the tank completely—and I mean ‘topping it off’ to get every last drop in, my fuel gauge usually looks like this (see the first picture, 01).
That picture was taken immediately after starting the car after filling up the tank (I was still at the pump). There have been occasions where the needle has gone all the way to just slightly past the 4/4 mark (just like the Boxster always does), but it usually lands below as seen in the photo.
However, today I was down to the warning light coming on telling me I’m low on gas. I stopped to fill it up and it only took about $30 worth. That’s odd, with gas prices here and filling up an almost empty tank, that should have been between $44 and $48 (that's what the Boxster runs). I tried to top it off but it wouldn’t take any more, as if the tank was full.
So, I got in the car and started it, and (just like before) this picture was taken immediately after starting the car after filling up the tank (I was still at the pump) - (see the second picture, 02).
Just barely over half a thank.
Any idea what could be going on with this?
