Often, simply clearing the fault codes after replacement is sufficient.

According to BMW fault code definitions, D52C44 is generally described as:

Use a tool or the hidden dashboard menu to verify that the voltage is stable (usually between 13.5V and 14.8V while running). Inspect Ground Straps: bmw error-d52c44
