Help With A Couple Of Things

[BELLER]

I HAVE JUST BOUGHT 1992 525 TOURING GREAT CAR BUT HAVE A FEW THINGS I WOULD LIKE INFO ON IF ANY ONE CAN HELP
1: SUSPESION LEVELLING LIGHT COMES ON AFTER 5 MILES ( HAVE CHECKED LEVEL)
2:WHAT SORT OF FUEL ECONOMY SHOULD I EXPECT
3:WHITE SMOKE WHEN START UP GOES AFTER COUPLE OF MILES (DOESNT APPEAR TO USE ANY WATER TO SPEAK OF AND OIL APPEARS OK (I HAVE DONE 1000 MILES AND HASNT GOT ANY WORSE) IS THIS THE NORM
4:NEED A NEW BACK LIGHT

1. never heard of a suspension levelling indicator, but then again i have a 1990 e34 so it could be a newer feature.

2. My car gives me approximately 10litres/100 km's. again that depends on a number of factors.

3. could be water evaporating??

4. back light?? can you be more specific??
