Porsche 2008 Cayenne S Shaking VIOLENTLY

[ozkenny]

I start the engine, and the engine warmed up.

Car starts to shake vigorously, and check engine light pops on. Car was on park.

 

I quickly turn off engine, and restart it, and the check engine light is gone and the car seems fine but not perfect.

What could have been the reason? 

Is this serious and would cost a lot of money??

Read the fault codes ...........

Then Check coils for cracks first if no codes found.

After that the list is longer and more involved especially if you don't have a code and it's intermittent. Good luck.
