While driving on the city street for about 10 minutes when a message "fault-fuel gauge" popped up on my instrument cluster. tried to fill the tank at the gas station but then the tank was full however the fuel gauge incorrectly indicating the tank is only 1/2 full.message would intermittently come on while driving. this vehicle was manufactured in june 2014 not recalled nor corrected by porsche manufacturer in their recall of 2014 model. car mileage is only 39,563 and this cars vin was not included on porsche recalls. this particular fault is exactly the same fault as all the 2014 cayenne porsche has previously recalled.carfax report on this model/vin states no recall. it would be dangerous to take this vehicle for a long drive due to inaccuracy in fuel gauge reading as vehicle can dangerously run out of fuel and stalling and increasing risk of accident.
Fuel guage error even when tank is more than half full, fuel gauge error pops up intermittently while driving.
Porsche diesel emission compliant fix: - porsche was required to apply emission fix to 2014 cayenne diesel - diesel emission settlement requirement is the emission fix "..will not result in any noticeable changes to the driving characteristics.." - in jan 2018, emission fix was applied to 2014 cayenne diesel - right after fix, the car showed 2-3 sec lag from the stop. at stop, when gas pedal is pressed, the car does not accelerate for 2-3 sec, then it "jumps" - in may, car was taken to porsche dealership. dealer stated that this lag is normal after fix, even though there was no such lag before fix - porsche dealership installed latest software on the car in may. after that, lag decreased from 2-3sec to 2 sec. but the car still has abnormal lag - it feels unsafe to drive the car, when merging to roundabouts, when merging from the stop - a complaint was filed with porsche cars of america. requirement of no "... noticeable changes to the driving characteristics" was discussed. porsche said that the performance is "as designed" - clearly, when car was purchased in 2014, there was no lag. that's when the car performed as designed. - emission fix noticeably changed car driving characteristics, it made the car feel unsafe. pressing gas pedal from stop does not result in smooth power delivery, it is not clear if the car will drive or not for 2 sec
