Kindly note I bought a second hand BMW from dealer. For few days fuel consumption was okay around 6.5 ~7.4 but in a morning few minute after run vehicle I receive check motor alarm number p2096.
Acceleration is fine, there is not any trace of black smoke or wrong smell from exhaust, shifting gear is okay without any delay in engine RPM, easy start engine in cold weather too. However check-light and code erased and not coming back again but fuel consumption is increased to 10 litters and some time is 9 and in beginning of cold start is around 12 litter according car display and not meet 7 litter any more in light gear condition on flat road with gear number 4. I read and see all possibility via internet and YouTube and record OBD II data as follow :
In stall engine RPM : 700~720
ETC (‘C): 85 / IAT(‘C): 42 / AAT(‘C): 11
SHRTFT: -3.1~ -3.9 / LONGFT: 10.9 / O2 : 0.415 / MAF:2.28 / T.P:12.5
But when pushing break pedal several time in stall condition parameter become as follow :
ETC (‘C): 78 / IAT(‘C): 44 / AAT(‘C): 18
SHRTFT: -3.0~ +7.0 / LONGFT: 10.9 / O2: 0.735~0.775 / MAF:2.28 / T.P: 12.5
have the same problem?
