Reported cause
i've had this warning light come up last week on my 996 TT (and previously the PSM/ABS lights) - diagnostics showed it was the oxygen sensor, which is being replaced next week.

changed lambda as garage recommended,pulled her out of garage left ticking over sounded like was missing from one exhaust sort of uneven tickover and smeel of fuel still, got into car check engine light was on,turned her off and re started revved her and light is out took her for run oil pressure spot on, temp spot on running sweet,minimul soot on exhaust pipe but still more than other side,only seems to smell of fuel when cold,and miss slighlty ?any ideas guys new plugs last service and coil packs in last 12 months.
Leading evidence: 'oxygen sensors' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'oxygen sensors' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Replace lambda as garage' (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.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

Suspected cause
As you say a flashing CEL is usually emissions most likely a sensor, the sooty tail pipe may be due to overfueling on one bank due to what ever issue you have, if it is over fuelling then it will toast your exhaust cat before long so suggest you take it in and get the codes read and rectified ASAP

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.

the other day after about 10 mins driving from cold the check engine light flashed(manuall says emmision controll light) a couple of times and whent off drove for severall hours and didnt show again,noticed that left exhaust seems more sooty than other any ideas ?
If you can then get the codes read then do.
If you carry on driving it and it doesn't appear again and there is no obvious problem with the car then I wouldn't worry about it.
Although it is odd it didn't stay on as it should do until cleared or the ignition has been cycled 7 (i think) times.
MAF :?: :?:
I'm probably wrong but a common problem as I understand.
That & coil packs
Someone will probably be along to correct me shortly :grin: :worship:
yep
hasnt done it since but other day pulled her out of garage and sounded like it was missing,then when warmed up was ok,idle is sometime eratic on tick over but ok after a few seconds is fine,coile packs hav been changed last year,noticed one tail pipe sooty than other ?light havnt come on since.
still same
