Hi All,
Ok so bit of a long story but best to tell all of it and get a fair view from you. Bought the Mrs and Gen 2 987 Boxster around this time last year. The garage replaced all the coolant pipes before we collected but seemingly didn't let it self bleed enough. A week later on her first longer journey the temp went sky high and said low coolant level. She stopped immediately and the garage recovered the car and her.
They drained and re filled the system, kept the car for a week and did about 200 miles to ensure it was fully bled over long and short journeys. The car kept perfect temperature and we got it back.
Then every so often, with absolutely no pattern it gives a big puff of white smoke on start up. It went back in and they replaced the air oil separator and all the pipework too. The parts were bought from local Porsche dealership and we thought all was sorted. Then a week or so later we get another very smokey start up.
After continued random smokey start ups, it went to a Porsche specialist who removed and cleaned out all the inlets from the residual oil. that had been left before the air oil separator was replaced. They advise it could still take a few months for it to burn off and clear completely. However, nearly a year later it still does very smokey start ups on random occasions. Since the clean out the car has done about 4000 miles.
The car holds temperature perfectly all the time, it's not used and ounce of water/coolant or oil in all that time but yet we still get this smoky start up from time to time.
Sometime sit can do it twice in a few days, other times it won't do it for two weeks :frustrated:
I'm now thinking could it be a faulty Coolant Temp sensor or mass air flow sensor??
Is it getting a false reading and putting in too much fuel on start up particularly even driven lightly the car is bad on fuel.
I know everyone says they can give a little puff of smoke on start up, which sometimes it does and no issue with that but this is a lot.
Its the fact there's no pattern making me think is it a sensor?
