Reported cause
The root cause is hard to decide from a light, so you will need someone with some gadgets to check it.
Leading evidence: 'hard' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'hard' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Check light' (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.

The check light was a faulty Mass air flow meter, fixed under warranty.

A five minute check will reveal the cause of the problem.
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.

Out of the blue the check light has appeared !
Anybody know if it will reset itself, or is it a dealer job ?
Car has running absolutely fine. The book says emmisions, but I can't see or hear anything wrong.
The CEL will come on with an emissions related fault, and has to be cleared by a code reader/scanner. Unless you fix the fault, however, it is likely to come on again. Where are you located? I might be able to help.
Hi Richard,
I live in Swanley Village in Kent.
I just thought it was strange for it to appear out of the blue... I would have expect loss of performance or poor running etc
I most likely will call Lindbrook on Monday and also have a 36k service. The car is on warranty and has had all of it's Services at Porsche Mid Sussex, but some of their personnel depress me.
I looked at your web site, and thought that if you were in Bracknell I am just down the road.
The CEL comes on for some faults that you would not notice when driving. For instance, if the car was slightly over or underfuelling you might not notice it, but the computer is sensitive enough to pick it up. If your warranty covers it, then take it to the dealer. A five minute check will reveal the cause of the problem.
arrh ... there are 2 of us , one Bracknell and Swanley, but I am often over your way.
Would I very high speed run cause this ? let say I was at Brands Hatch on the main straight they renamed M2
Possibly.
The car has a sensor before and after the catalytic converters.
There are 2 cats, one for each bank, so four sensors.
If the cats were damaged, or any of the sensors failed, or even had a loose wire, then the light would come on.
The harder you drive it, the more likley it is to show that there is some problem with the exhaust gases.
The root cause is hard to decide from a light, so you will need someone with some gadgets to check it. Could be cheap, or not so cheap. A loose wire is the lowest cost option.
Andy
What Stuart says is absolutely correct. I have got the gadgets, and if you want to pop in when you are over this way I'd be happy to run them for you. I'll email you with my number.
I took the car to Porsche Tonbridge.
I had booked it for the 36k mile oil service and the check light.
Was told no service required as the service interval is 12k miles OR annually.. So since I had only completed 6k, the service will be due in Dec.
The check light was a faulty Mass air flow meter, fixed under warranty.
