security breach code number 23
that has been flashing at me all day. anyone know what it is or more importantly, what the implications are should it be discovered? if someone has been tampering, i dont want the blame for it 
stop being doggy,take the magnet of the gear box sender,lol, 
is it a seimens, stoneridge or actia?
- if it’s a siemens then you’ve got a sensor authentication error. to cover yourself you best get it checked at your nearest digitach centre asap.
found these on t’internet which lists all of the siemens fault/events codes.
im pretty sure its a siemens and those codes do match the ones i have seen for other things
Yes its a sensor problem ive hade that before
Was it a DAF? Used to get that code a lot, almost every time the engine was started, when we had DAF’s
Probably just needs the sender pairing, 5 minute job at your local tacho station 
yes it was a DAF. 58 plate XF

Exactly the same age and model as the one I used to get the fault code on, must be a DAF thing. It seems to think every time you start the engine that there has been a power interruption to the tacho.
