Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order.

Turned out to be both lower valve covers leaking onto the exhaust.

Suggestion
Warm oil after a drive, check with car on the level, wait a few mins - even 5 - before checking via dipstick and dash gauge (but the dipstick level is 100% reliable...)
Leading evidence: 'lower valve covers leaking onto the exhaust' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'lower valve covers leaking onto the exhaust' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Check with car' (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.

Suggestion · Original poster
I think it may have happened just as I lowered the temp setting on the climate control.
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.

Hi all,
I was just driving down the road in my 993 today, suddenly thick acrid smoke began pouring out out of the air vents. I stopped, and had to evacuate the car of my 2 year old sitting in the baby seat, as i thought there was a serious fire. A kind driver even stopped and approached with a fire extinguisher, the smoke was so bad.
It stopped after about 5 mins, and i decided to get the car home - with no futher incidents.
I was driving slowly, and had been for the whole journey, as we were in town. I think it may have happened just as I lowered the temp setting on the climate control. The car sems fine now, but still a bit smelly, maybe just the residual smell from before.
Anyone had any similar experience? any one know what might be going on?
Regards
Bob

If oil gets onto the exhaust through clumsy topping up and/or faulty heat shields, that can cause smoke to come from the vents. But this sounds different and maybe more serious... What colour was the smoke?
I'd get the car seen to soonish...

Thanks for the reply. The smoke was light grey. I'm pretty sure it was burning oil. I've noticed today that the right hand silencer looks oily, could the oil resevior have overflowed? it is reading slightly high on the oil level.

Maybe you've overfilled with oil...? Check out the handbook re procedure... Warm oil after a drive, check with car on the level, wait a few mins - even 5 - before checking via dipstick and dash gauge (but the dipstick level is 100% reliable...)

Thanks for your advice everyone, Turns out it was an oil, as everyone who replied thought. - both cam covers were leaking oil onto the heat exchangers!
all sorted now
cheers bob

I had exactly the same thing happen with my car, I thought it was a fire during a track day. Turned out to be both lower valve covers leaking onto the exhaust.
How much did it cost you to fix?
Migration info. Legacy thread was 43438
I had the same symptoms recently and it was diagnosed as the same problem. Mine cost £400 at an indepedent. This included new cam covers as apparently they are prone to warp and leak again. Cost broke down to approximately half for labour and half for parts.
