Does anyone know what options 0840 and 08S4 mean?

Just received our X5 and I was going through the details on the car and noticed a couple of things I am not familiar with. Does anyone know what the below are?

• High speed synchronisation 0840

• Decoding, variable light distribution 08S4

840 increases the top speed limiter and dictates the tires your vehicle is equipped with. On some other vehicles, it also determines whether or not there is an additional radiator or cooling mechanism.

8S4 disables the variable light distribution functionality, which changes the way low beam lights work in various situations: city, standard, highway. If this functionality were enabled, the beam pattern would adjust for these circumstances, i.e. narrower beam for city and wider beam for highway use. North America specific, unfortunately.

So I presume you can code and activate 08S4 variable light distribution?

A while back there was a thread on Bimmerfest regarding anti-dazzle for LED headlights where some coders believed that they figured out how to activate the feature. You an read it here.

Euro cars have this feature for the LED headlights but for USA it is disabled or the hardware is different.

Is 0840 only for M Sport? My xline has the 20" w/ performance tires, but I can't get it past 130 mph? Dealer told me it would have the increased top speed?

Yep. Option #840 only comes with M sport. On my 135i it was M sport options ZSP or ZMP.

I'm curious if I add 840 to my VO would it increase my top speed to the 155 on the M-sport?
