B2005 on Audi
Invalid Data Record
B2005 on Audi vehicles indicates invalid data record. Au7o has documented this code across 1 Audi model — most commonly on S8. 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.
Common Causes of B2005
- •Corrupt or missing parameter data in the control unit
- •Incomplete or aborted SVM (Software Version Management) coding session
- •Module coded to the wrong part number or variant
- •Control module firmware fault
- •Low system voltage during a previous programming attempt
B2005 on Audi by Model
Audi S8(1 issue)
- 2013-2015 S8 COD Vibration with J931 Basic-Setting Fault - Diagnosis Required2013-2015
Audi TSB 2036392/6 covers 2013-2015 S8 4.0 TFSI vehicles with vibration around 1000 and 3000 rpm and possible B201000 or B200500 in the sub-frame mount controller J931. Work on electrical-system controllers J519/J520 can deactivate J931 active-mount basic settings. The bulletin does not establish that both mounts commonly fail at 60,000-100,000 miles.

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. On Audi specifically, this code is documented across 1 model.
What causes B2005 on Audi vehicles?▼
Common causes on Audi: Corrupt or missing parameter data in the control unit, Incomplete or aborted SVM (Software Version Management) coding session, Module coded to the wrong part number or variant, Control module firmware fault, Low system voltage during a previous programming attempt. Specific causes vary by model and year — see the per-model sections below.
