The following preconditions act as switch-off inhibitors and prevent the engine from shutting down:

• Engine adaptation (e.g. cylinder adjustment)
• Regeneration of the diesel particulate filter
• Carbon canister needs purging
• Insufficient knock resistance of fuel
• Engine fault
• Engine coolant temperature
  • below a defined value (depending on engine version approx. 20 ‐ 60 °C)
  • above a defined value (depending on engine version approx. 100 ‐ 130 °C)
• Automatic transmission not ready
• Gearbox adaptation active
• Drive position “S”, “M”, “N”, “R”
• Driving surface incline too great
• Assist system active (Active Cruise Control, Parking Assist, Hill Descent Control)
• Stop-and-go driving
• Last MSA stop was too long
• Air conditioning requirements:
  • MAX AC button pressed
  • Defrost button pressed (request to defrost the windscreen)
  • high blower speed and low blower temperature, compressor button pressed
  • high blower speed and air distribution directed to windscreen, compressor actuated
• Ambient temperature ≤ 3 °C
• Engine speed > 1200 rpm
• Battery condition:
  • State of charge too low
  • Measured battery state of charge not plausible
  • Battery temperature too high (approx. 50 °C)
  • Starting voltage drop from previous ASSF start too low
• Vehicle rolling

Thank you for the extensive list. A lot of checks as soon as I lift my foot of the brake! I also switched off the Auto Hold thinking this also made a difference to the stop-start however it's. not a listed item.
