Most Reported On
B2005 is an OBD-II diagnostic trouble code meaning “Invalid Data Record.” A control module has found that the parameter or coding data set stored in its own memory is invalid or corrupt. The module cannot verify its configuration, so it limits or disables its functions until a valid data record is written back. On Audi 4.0T V8 models it is most often seen in the active engine mount (subframe mount) control module J931, where it appears alongside B2010. This code is most commonly reported on 2013-2015 Audi S8 (4.0 TFSI vehicles with reproducible 1000-3000 rpm vibration; diagnose J931 before mount replacement).
