-What can cause rough idle and throttle hesitation? O2 sensors? Catalytic converter? Oil separator? And no fault code except faulty oil pressure gauge + check engine light.

-What can cause bouncing oil temp gauge, faulty ground? Oil pressure gauge was just replaced

 

I would say your best bet is to scan it and go from there. The only thing I've seen like that on a Panamera was a bad high-pressure fuel pump causing rough idle and throttle hesitation.

 

Dealer is saying its the faulty oil pressure sensor, but that is bs right?

 

It seems like a stretch, but it's possible that the rough idle is due to the demand-controlled oil pump repeatedly switching between high and low pressure due to a faulty pressure sensor.

 

I was hoping it would have, but they installed a new one allready.

 

What year is your car ? Was it covered under warranty ?

 

2010. Yes the car was towed due to oil pressure monitoring failure code.

 

So did the dealership give you a reason for the failure ?

 

I also have a 2010 turbo with a bit of a ruff idle.

but not fault codes

 

They fixed the faulty oil pressure sensor and after they did this, my oil temperature sensor has now started jumping up and down. They have contacted Germany, but no answer yet. Frustrating.

After the turbo recall, my car has now otherwise performed better than before, hesitation seems gone. Although have only had the car for a few days. Im guessing my turbos were failing

 

Please post if you find out something. My car seems better after the ti-al turbo recall, but the cold weather is only starting so will see if it starts again. My rough idle was worse when cold.
