Also for peace of mind replace the bolts that hold down each coil. (I wish I could give a price for this but the parts guy just handed me 8 free so I don't have an invoice with pricing)....

 

Thanks, first renewing also the spark plugs as soon I receive them and then see what happens.

At this moment my iCarsoft gives the following codes:
(Translated from Dutch)

002087: Current sportmode, sending, defective
C120A1: Error in unit central differential
00208A: Current sportmode defective

Ps. This problem was caused just after pulling up in Sport mode

Sport mode defective us mist likely because misfires were detected so car forced out of sport mode and placed into reduced power mode. Very confident the new spark plugs will repair this.
you seem to have an error due to differential. If you haven't replaced front and rear diff oil, now is perfect time for sure, then clear error. See if it returns.

 

Plus if you have mot done maintenance on car, replace pdk fluid (about 400 bucks if diy, couple thousand if done at dealer).
also replace air filter (remove front bumper to do it...cost about 60 if diy, about 600 done at dealer).
also, good time to replace brake fluid..
also good time to replace power steering fluid..
I have diy on each on this forum..
these are important maintenance on any car..
If you plan to keep car for while,, do those too..
Make sure your engine coolant topped up too,, and tested..
If old,, replace that fluid too..

The above will save you thousands in repairs.

 

Yes the following maintenance was planned for next weekend but then this happened:
- Air filter
- Interior filter
- Oil + oil filter
​​​​​- Brake fluid
- Front + rear differential oil
​​​​​​- Spark plugs + coils

- I will add the coolant fluid & power steering fluid

I already have saved all of your DIY’s 😎

 

Update: a week ago I send the video to an Porsche specialist and he was very confident the camshaft adjuster bolts were broken and long story short the repair should have cost me somewhere between €8-€10k. I was stunned by this bad news… he said first check the compression each cilinder and of one one side the compression is 0, the camshaft is standing still and the valves are bent…

But my good friend and car mechanic was just here and first there is no mechanical saunds hearable in the engine due to broken bolts and compression on all cilinders is perfect.
Just placed the new spark plugs and coils but still not running fine.

So what’s next to check? Another specialist said it could be the HPFP and he can measure the pump if it is faulty or not. In my research I also found out that it could be an defective fuel pressure sensor?
I think I have to call the second specialist to check my car with his PIWIS.

 

PIWIS scan is a great idea. It will help you find the problem...

 

ok, with spark plugs gap is clear, just wondering what tuners say about how often to replace spark plugs ? I mean that probably on tuned car should be more
often
Official Panamera Turbo Maintenance Schedule says: replace spark plugs every 30,000 miles (45,000 km) or every 4 years - this sounds to me way to long interval,
on my tuned Turbo S spark plugs were normally worn out and had to be replaced after 20,000 km

And regarding ignition coils - is there any estimated life time for them ? I assume that if to replace spark plugs on time, before they start failing then ignition
coils should last forever, correct ?

 

 

Follow torque guidelines for both bolt. My diys have these listed somewhere for shock ir valve cover work, etc. Once you see rubber crack, replacement needed. Should not be spinning as torque and bolt fit will prevent that.
about 100 bucks for new replacement.

 

replacement. Tour plug coils, life differs. From my experience ut is the plugs that go first.
only problem porsche coils have is that they tended to crack. Once you see a coil with a crack it its body, replace as it affects impedance internally.
I was going to do experiment (never did) where I replace plugs only, to see how car behaves assuming no cracks. Just replaced it all, extra 60 bucks for new oem plugs.

 

no doubts regarding cracks, but I don't see any cracks, and of course bigger rubber is made to be solid, I mean in one piece with plastic part, but the one I
marked in red, I think it has to turn inside plastic housing, like upper control arms bushings, for example ... Otherwise I don't understand the purpose of
this damper...It should absorb 'movement' of the engine

 

It does not turn. The UCA bushings also do not turn.

 

was your car still running with such shape coil packs ?? I had 3 messages: Engine Check, Transmission Fault and PSM Failure on message screen and bunch of
faults when connected diagnostic, car engine was shaking like hell, reason was 2 coil packs like on your picture.

 

That's one big *** crack.
The pack is done. This changes the impedance, moisture gets into the coil. Not good at all.
Check all the other coils.
When I replace coils, I do them all, or you will find yourself in the engine often, looking and replacing one at a time.
