3 known faults with sources
Engines: Eléctrico (Electric)
MEB platform 12 V battery and softwareElectrics and software
- Engine / equipment
- MEB platform EVs: VW ID.3, ID.4, ID.5, ID.7 and ID.Buzz, Skoda Enyaq and Elroq, Cupra Born and Tavascan, Audi Q4 e-tron
- Period mentioned
- 2020–2026
- Symptoms
- The car will not start or wake up after standing even though the traction battery is charged; 12 V battery warnings; screens that freeze or go black; charging sessions that will not start or cut out.
- Possible cause described
- The 12 V auxiliary battery frequently suffers deep discharge, and low voltage in turn causes starting and charging faults. Early software versions (1.x and 2.x) had many bugs; the ICAS1 control unit manages comfort and energy.
- Check for the garage
- Check the 12 V battery condition and the quiescent current draw, and confirm at the dealer that the car has the latest software. With ODIS: high-voltage battery (8B), high-voltage electronics (8C), charger (8E) and ICAS1 (C7).
- Cost cited in the source
- 12 V battery or update: approx. €0–370 (converted from dollars)A rough figure from the original database, not an up-to-date quote.

The ID.3 will not get ready to drive: flat 12 V battery and false warnings from the first softwareElectrical and electronic systems
- Engine / equipment
- Early Volkswagen ID.3 electric (software before version 2.0)
- Period mentioned
- 2020–2021
- Symptoms
- The car will not get “ready to drive” even with the main battery charged, because the auxiliary 12 V battery is flat. The first software also showed warnings with no real fault: an intermittent airbag light, a false electric-drive fault message, charging that does not start at some chargers or a temperature gauge that does not work.
- Possible cause described
- The 12 V battery discharge was one of the most frequent complaints on early ID.3s (according to L'argus, in 2020 54% of ADAC call-outs to these cars were for it). Volkswagen fixed it with software updates 2.0 (December 2020) and 2.1 (fitted in production from 22/2/2021), together with the other false warnings; to move to version 3.0 the car first needed 2.4, which required replacing the 12 V battery with a new model. In ADAC's long-term test, a 2021 ID.3 failed to start at 158,000 km because of the 12 V battery, and Volkswagen said a software update would have prevented it.
- Check for the garage
- Measure and test the 12 V battery and ask Volkswagen which software version the car has; if it is not up to date, ask for the update (it may require replacing the 12 V battery). If warnings appear with no clear fault, check the software first before replacing parts.
- Cost cited in the source
- The update, at the dealer; a new 12 V battery cost €456 in the ADAC test.A rough figure from the original database, not an up-to-date quote.

Yellow electrical system message and less range from cells that self-discharge (2021–2023 ID.4)High-voltage battery
- Engine / equipment
- Volkswagen ID.4 electric
- Period mentioned
- 2021–2023 (US model years)
- Symptoms
- The yellow electrical system fault message appears with code P0BBD00 and the range can be lower or keep dropping.
- Possible cause described
- Some high-voltage battery cells self-discharge too much because of a production fault, which reduces capacity and range. VW improved battery production from week 46 of 2024, and the workshop replaces the affected cell module (bulletin 93-24-01).
- Check for the garage
- Ask the workshop to read the battery control module (address 008C) and apply bulletin 93-24-01 if code P0BBD00 appears with one of the listed symptom codes.
- Cost cited in the source
- No verified estimate; ask the garage for a quote.A rough figure from the original database, not an up-to-date quote.
