U0507 Invalid Data Received From Folding Top Control Module

Check engine lightUsually off

The folding top control module runs the power soft top or retractable hardtop of a convertible: it moves the top through hydraulics or motors, watches latch and position sensors and blocks the sequence when something is in the way. Other units need its status, for example to drop the windows, warn while driving or release the trunk lid. U0507 is logged when that status arrives in an unusable form. BMW shows how much hinges on clean data: in 16,286 convertibles of the 4 Series built 2013–2015, the CVM misread luggage compartment sensors due to software, which could defeat obstruction detection and damage the hydraulics (SI B54 02 17, reprogramming). No maker publishes U0507 itself. U0206 means no contact.

Likely causes

Top control module software error (BMW F33/F83 example)
Damaged wiring to top position or latch sensors in the folding area
Water reaching the module from a leaking top drain

Symptoms

  • Top refuses to open or close or stops midway
  • Top not secure warning while driving
