P0EE2 A/C Refrigerant Distribution Valve B Stuck/Open

P0EE2 says the second refrigerant distribution valve, B, stays open or fails to close. In plug-in hybrids and EVs such shut-off valves route refrigerant either to the cabin evaporator or to a chiller that cools the battery; Egelhof sells solenoid versions with 12 V or 24 V coils for exactly this use. The fault is inferred, since the module sees pressures or temperatures that would not occur with the valve shut. Audi documents it on the A7 55 TFSI e (2021-2023): P0EE200 is stored in thermal management unit J1024, address 00C5, and the MIL comes on. TSB 2071040/1 blames the J1024 software and lists an SVM update from container 4K8909476J/K/L to 4K8909476V; the HV charging cable must be unplugged during flashing. Valve A stuck open is P0EC9.

Likely causes

Thermal management software misjudging the valve (Audi J1024)
Valve seat contaminated or armature stuck open
Weak coil that no longer moves the armature

Symptoms

  • MIL on
  • Weaker cabin or battery cooling
  • Often no noticeable effect beyond the warning
