Hi and welcome Everyone,its my first post. Forgive any errors if present.
Have a wee problem with T5...
Operating status-Group 028 Accelerator pedal position sensor in BNZ engine when on Idle "1000" where 1 its a signal from G185 ( Idle switch ON, when G79 operating from 0.1-100% it changes to "0" ). Now..
Randomly, operating status changes to "1010" where the other "1" correspond to "Increase Idle speed", and engine ECU does that.

My question is : what may trigger this state, which components and where I can find info about it ?

My observation:
- Alternator operating like it should, no problem with loads etc, when operating status is 1000 and all electrical components active/under load nothing happening, no change to status
- When engine its started first time in the morning and not turned off/operating for x time, this issue not appearing. But just turn off and restart the engine ( at any point after first start ) after 30 sec or sooner status go to 1010 and Idle rises...sometimes status 1010 kicks in immediately after start.
- No A/C
- Atmospheric pressure working correctly ( been compared with other vehicle ) at sea level.
- Altitude status its not operating when 1010 its active
- EGR and DPF system its disabled in ECU (remapped )
- when move of with 1010 status and driving for a while ( random times ) Idle back to normal and status is 1000

Running out of ideas what causing this state...
