warnlicht/lamp in tachometer

[MXMXM]

Mein tachometer ist repariert werden(ist das richtich deutsch?).
Der tacho welle oder ein zahnrad war kaput. Ich habe grossere reifen und ein conversion war notig for de tachometer. It didn't really fit and it broke.
Ok Mercedes fixed it, but a warning light keeps burning a red light with a triangle. also whel al the power is off. i have to take out the nalo key from the battery to get it off.
what is going on?

Beim Tachograf heist das soviel wie keine Tachoscheibe, schlecht verschlossen.
Beim Tacho weiß ich nicht was es bedeutet!
Vielleicht irgendwas mit dem Bremsluftdruck?

I think, the tachgraph isn`t correctly closed or there is no or the wrong "disc" (in German, it`s called "Tachoscheibe" or "Schaublatt", I don`t know the English word) in it

Greetings Ulli

It is a two man tacho, it had only one tachoscheibe in it.

Thanx max
