I have a 2003 boxter. kilometerage is 100,000.

today i started the vehicle and a large plume of white exhaust appeared. It cleared and did not persist after the vehicle was running. Drive to work - no problems; although check engine warning light appeared ( it is also time for service). Parked. REstarted several hours later - same result. again did not persist when car was running. drove home. parked. turned off engine. immediately restarted. same result - big white plume of exhaust which did not persist while car was running.

i have appointment with porshe service centre this week but was hoping for some clues prior to dropping the vehicle off.

can anyone suggest cause(s) of this sudden issue.

thanks

 

Very possibly an oil air seperator that needs to be replaced. Some smoke at start up is normal, but not a huge cloud.
