I dont know Porsche vehicles at all...never had the pleasure of driving a Carrerra....
But ..
First of all...have you driven/compared the vehicle to like vehicles? Is it design intent or is there a problem?
I would first see if the dealer has another vehicle to compare this to.
I would also get the Service manager involved,if necessary the Dealer principal and contact customer service at Porsche.
You pay huge money to drive vehicles today and especially a Porsche...
Has the Dealer service personnel contacted Porsche technical assistance?
All manufacturers have tech asst and they can call for help...sometimes they may not have an answer but it will get the ball rolling...plus,they can look into their data base and see if other similar situations have been called in and what was done to correct them.
Sometimes it can be where there is no known fix at this time,but this makes Engineering aware of the situation and they will work on a fix!
Once a case is called in/made ,it is documented and when the repair is complete,dealers are required to contact them with their findings and corrections..
When a case like this occurs and it cannot be repaired and it is determined there is a problem with the vehicle, they will send out an engineer to work side by side with the dealer tech to find a solution...seen this a few times with GM vehicles......
Keep us posted
Jim
