Suspected cause
You should verify if there is a high engine oil comsumption, the engine oil type (eventually change it and the oil filter and put on new Castrol oil) or check the quality of the petrol you use (even if I do not think is due to the petrol as you asid it only smokes at startup).
Leading evidence: 'petrol as you asid it only smokes at startup)' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'petrol as you asid it only smokes at startup)' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Check oil level' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

3 weeks ago I brought a 02 996 c4s coupe from main dealer but have noticed quite alot of smoke pouring out when starting it wether warm or cold and also it can happen when i am high up in the rev range, it only does this occasionally. I was worried as I thought this could be the start of something serios so i contacted my dealer who arranged for the car to be taken in . the next day they told me it is a very common that 996's smoke and that they could find nothing wrong with the car even though it bellowed out smoke from a cold start when they came round to pick it up am I being lied to and has any one else had this problem!!!

I do have a 2001 996 C2 cabrio, even if mine has the 3.4 L engine and I assume your have the 3.6 L engine, its does not smoke at all.
Of course in the very cold days you may see a little of steam but not smoke.
So depens of the type of smoke (burn oil smoke can be recognised by the smell) but if the smoke is a lot could be a problem with the engine.
You should verify if there is a high engine oil comsumption, the engine oil type (eventually change it and the oil filter and put on new Castrol oil) or check the quality of the petrol you use (even if I do not think is due to the petrol as you asid it only smokes at startup). Anyways you should first try to identify the type of smoke or ask for a second opinion.

Hi Simon,
I've heard of this problem occuring on the turbo version, where it's caused by oil contamination of the air intakes. Over filling the engine oil causes the problem.
It's easily solved by cleaning out the oil of the air intakes.
Have you checked the oil level?

Mine definatly does not smoke. When looking from mine I did come across a tired 996 c4 that smoked on start up when the guy evetually started/thrashed it. Walked away.
It is not smoking all the time, which I would say it better news than if it did. I don't think any modern car should smoke (oil smoke which is blue'ish) as it would not pass emmisions mot testing.
Which dealer did you take it to ? Get a second opinion from another Porsche specialist.

Mine smokes from time to time when I start it, doesn't seem to be a regular problem and once the car has fired up there appears to be no more at any other time :?
