I got a puzzeling limiter thing going on here,
In the UK (on private road obviousley) my M3 will hit the speed limiter at 155mph as it should.
Yesterday on the autobahn I went for the limiter and it just kept going, it got to 179mph and still pulling hard, but I had to back off due to traffic ahead and a bend I wouldn't want to try at that speed. While doing 170mph on the clock afterwards it was showing when I reset the average speed it was doing 167mph.
Are the limiters connected to the satnav so it lifted the limiter in Germany or has it just stopped working :confused

most speedometers are out there is an allowable error of 7% +10 mph that is considered NORMAL!, but other things to take into consideration are tyre sizes etc too.

The limiters are not region specific if your car has a limiter fitted it is limited and that is that. However BMW speed limiters are based off the speed sensor in the diff, not the actual speedometer. So it will kick in in a specific gear at a specific RPM

Everything the same, car and tyres the same only difference is German fuel.
I was wondering as to satnav location as I saw a skyline on Topgear that did this and thought it would explain mine on having a limiter on Sunday.

Seems weird dude, mine tops out at 155 and will not go any higher even tho it still has plenty in the rev range left. Iv been told if you get these mapped there good for 170mph so maybe has a map? But this dont explain why it tops out at 155 over here, it wont have anything to do with the sat nav as this doesnt have any control over your ecu as the skyline does. Confused :hihi

In the UK the other week it topped 155 in 5th then stayed there in 6th, same as my last M3 evo (e36) did.
The other day it was in top and rolling on from 120 ish.

sounds like limiter might have stopped working, go back on the autobahn and try it again :)

only R35 GTR remove speed limiter when gps detects you are at a certain location.
