I hate my Pig!! Runnng like a bag of hammers

[Graeme Tate]

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

Please tell the exact year and model of the car. Also, all fault (error) codes.

The car is a facelift 2007-2008 cayenne S, the only fault code it is showing Is P0016 camshaft crankshaft correlation error

Check the crankshaft sensor. Sensor End should be clean and not damaged. Check the resistance also. 

Other correlation issues turned out to be timing chain issues, stretching, jumping a tooth, tensioners snapped/collapsed etc etc. 

More diagnostics required........

If the fuel was the root cause, dirt in tank, filter clogged now ?? How that relates to p0016 idk ??
