BMW fault code 001D
Heating/air conditioning
Water valve left
Module version: Heating/air conditioning (IHKR3)
Which BMWs have this version depends on the engine and equipment, so we don't list them here; AutoLingo for BMW reads which version your car has.
Reading and clearing it
Fault code 001D is a BMW code, stored in the car's heating/air conditioning, not a generic OBD2 code (P0xxx): a generic OBD2 reader only reaches the engine's emissions faults, so it won't show it. AutoLingo for BMW reads it with BMW's own diagnostic protocols, in plain English, with the details the module stored about it, and clears it after a repair. If a fault comes right back after it's cleared, the problem is still there.
The heating/air conditioning is on: 5 Series (E34), 3 Series (E36), Z3 (E36/7)
