Check engine light stays on
Josephine replied to Derek Pallet's topic in 986 Series (Boxster, Boxster S)
Thanks you so far, but... My UK bloke knows what he’s doing, has the unit you mention, it shows “P2096 - Post Catalyst Fuel Trim System Too Lean Bank 1”, he has shown me the clean blank graphs, assures me emissions are normal, changed 1 sensor, and still the lamp comes back. The code still leaves even the experts guessing because it says no more. So I could be forking out £60 an hour on a wild goose chase. He hasn’t charged me yet, as it was under a 3 month dealer warranty So...How critical is the sensor, seeing as today I was getting 37mpg at 70mph during a 200 mile drive? Thanks again, -

Hi, just joined 13.07.2019. My (very first Porsche) Boxster 986 (2003) 79,000 miles, 5th owner). keeps lighting up its engine check lamp. It’s been checked, one dodgy sensor was replaced, but the warning returned. I have not yet come across a decisive fix for this common problem, despite hours of reading forums. I suspect i could be running through a maze of smoke and mirrors here. All codes seem ambiguous. Does petrol octane have an effect? The lamp disappeared briefly when I gave it some 98 brew, but it still lit up again after 50 miles. Has anyone found a solid answer? What if I have the sensors disconnected. I hate driving with warning lights blazing, and the solution cannot be found, but further engine problems do not seem a real threat. My engine performance seems ok, even when the light is lit.
