Hi Guys, sme weeks ago i changed my vanos seals on the inlet cam of my e39.
all was fine have much smoother exceleration and more top end power and driveability
as it should when vanos is working correctly.
But in the last couple of weeks my fuel consumption had risen up greatly, black exhaust and
very rich smelling when ticking over and standing by the car.

air flow meter is all ok, The car drive,s all ok with good power, but have a VERY active liters per 100kms gauge
always on maximum with very easy excelerating.

Any ideas Guys
