Just moved over to BMW after owning 6 Mercs in a row.
Have bought an 06 520D touring 109 thou on the clock only two owners from new full service history but have a couple of concerns.

First problem is the MPG reading is only up to 32,1 after doing 400 miles and crept up very slowly surely not right i thought they should average about 39 mpg.
Second thing is it has the little triangle and fault messages one is BMW SOS not working another is right side number plate light which is working fine ? and last is right hand brake light which i think is the second one so that might be out.

Also looks like the nav dvd drive is not working keeps saying insert disc.

Any help will be nice.regards Dave
