The idle issues continue. I started a business so the 400e has been parked for almost a year.

Last July it was running great. Took it on a road trip, averaged 9.3 Litres per 100k (25.9 US MPG) which included some... spirited driving.

Thought my troubles were behind me but shortly after that it began to have a hot start issue. Lots of limp mode, etc... anyway, after a long break I'm back to troubleshooting.

Finally got a code reader and this is what I pulled:

• Socket 7 Code 3 Cruise control/idle speed control actuator
• Socket 8 Code 5 Maximum permissible temperature in module box exceeded - Base Module
  
• Socket 8 Code 8 Voltage supply for LH-SFI control module interrupted
• Socket 16 Code 13 Engine coolant temperature sensor, open circuit

Questions:

1. Is the Cruise Control actuator dual purpose? As in it controls the idle as well?
2. This appears to be the part number 0025458632 but it's referred to only as the Cruise Control Servo.
   
3. What does this mean? Is it melted? Base Module: Maximum permissible temperature in module box exceeded.
   
4. Voltage supply for LH-SFI control module interrupted. Does this mean it's not getting power? (car isn't starting at the moment)

Thanks in advance.
