How to check a used VW ID.4 battery: size, recalls, warranty and health (UK)

Published 2026-11-07 · Last updated 2026-11-07 · based on 25 sourced ID.4 data points and 31 sources

The ID.4 is one of the most common used electric SUVs in the UK. It shares the MEB platform with the ID.3, Enyaq and CUPRA Born, and it has a large published test dataset. This dedicated guide covers how to tell which battery a car has (including the newer 58 and 79 kWh packs), the 2026 UK battery recalls and the temporary 80% charge cap, Volkswagen's 8-year warranty, and how to compare a test result with AVILOO's data from 24,445 tested ID.4s. For the hatchback sister, see the ID.3 battery check guide.

All figures with method and date: used ID.4 battery data. Going to a viewing? Make a printable list of questions for the seller. MEB sisters: ID.3 · Škoda Enyaq · CUPRA Born.

1. Identify the battery

EV Database UK listings, checked 2026-11-07. Each size was sold in several model years; the table shows one listing per distinct usable size / chemistry. Early and mid-life cars are on a 400 V NMC pack; the MY27 Pure switches to LFP. Trim names changed over the years, so go by the battery size on the V5C, the advert or the service book, not the badge.

• Compare a test result only with the same pack. Most of our single-car UK certificates are 52 or 77 kWh.
• The ID.4 shares its packs and platform with the Škoda Enyaq and, for the hatchback, the ID.3.

2. Check the battery recalls

When we checked DVSA's recall file downloaded on 2026-10-31, it listed two high-voltage battery recalls that include the ID.4 (DVSA):

Volkswagen UK runs these as safety recall campaigns 93MV and 93MF for ID.3, ID.4 and ID.7 cars whose batteries came from one supplier between 2022 and 2025. It says charging above 80% may cause overheating and a fire risk, so it is temporarily capping affected cars at 80%, in most cases over the air; the car has to be online, with privacy settings off and the ignition on for at least five minutes, for the cap to arrive. Volkswagen reports no confirmed injuries but individual cases of property damage, writes to owners about a free dealer check, and replaces battery modules or updates software as needed (Volkswagen UK, checked 2026-11-07).

• Quick check at a viewing: Volkswagen says that if the cap is active, the charge-limit slider in the app or infotainment won't stay above 80% and slips back below it.
• Shared MEB context (ID.3 rows on the same campaigns, plus earlier ID.3-only battery recalls) is covered in the combined ID.3 guide.
• Other ID.4 recalls in the file are not about the battery (for example R/2021/409 steering bush, R/2024/221 seat bolts, R/2025/516 door-handle software).
• Run the free GOV.UK recall check on the registration (GOV.UK). If the car is affected, ask whether the work has been done and for the dealer's record. A car that is still limited to 80% will show less range on a test drive, and a battery test taken before the repair may not reflect the battery after it.

3. Check the battery warranty

Volkswagen UK covers the high-voltage battery of every ID. model for 8 years or 100,000 miles from first registration (whichever comes first): if a VW authorised repairer measures less than 70% of the original energy content, it is repaired or replaced. The warranty passes to later owners. (Volkswagen UK, checked 2026-11-07; Volkswagen UK)

• The warranty runs from handover to the first customer or first registration, whichever is earlier. The 70% is measured by a Volkswagen authorised repairer, not by a third-party test.
• A warranty repair brings the battery back to at least 78% of its starting energy content up to 3 years or 40,000 miles, 74% up to 5 years or 60,000 miles, and 70% up to 8 years or 100,000 miles, depending on the car's age and mileage when it is diagnosed (Volkswagen UK).
• VW's terms exclude loss caused by unauthorised work on the battery, not charging or maintaining it as the owner's manual says, fire, or excessive water such as pressure-washing the battery.
• Volkswagen says an Approved Used electric VW gets a multipoint check and a battery health certificate (Volkswagen UK). If you're buying from a VW dealer, ask for it.
• Our battery warranty checker works out the time and mileage left (All ID. models (UK): 8 years / 100,000 miles, below 70%).

4. Get an independent reading

A VW workshop can read the battery's health with its diagnostic tool (ODIS), and owners read the battery's energy content with OBD apps. Owner reports in our data include 2 VW workshop or dealer readings, for example 91.0% on an ID.4 (4.5 years old) at 70,000 km (Bolidenforum.de, n=1); 87.0% on an ID.4 1st Max 77 kWh (06/2021) at 105,069 km (meinID.com VW ID Forum wiki, n=1). On one ID.4 in a German forum thread the dealer reported 91% and an AVILOO test of the same car showed 93% (Bolidenforum.de).

Different methods give different numbers, so compare like with like: an AVILOO result with AVILOO data, a VW reading with VW readings. AVILOO calculates SoH with its own method rather than copying the car's figure (AVILOO GmbH). Riddermarks: 95.4% of 588 ID.4 77 kWh cars tested were above 90% SoH (average 80,321 km). (Ny Teknik / Riddermarks Bil) Test options and prices are on our buying guide, and how to read a battery health certificate explains each field.

5. Compare the result with what's normal

AVILOO medians are the middle value of tested cars at that mileage; the band shows where the central 99% of cars fall. Riddermarks (588 dealer tests, average 80,321 km, mean 93.6%) and Carla are averages from dealer tests.

• At 150,000 km the central 99% of tested ID.4s ran from 83.4% to 94.9%, so a good model average doesn't guarantee a good car.
• As a rule of thumb for all EVs, ADAC expects at least 92% at 50,000 km, 88% at 100,000 km, 84% at 150,000 km, 80% at 200,000 km (ADAC).
• Compare the ID.4 with its MEB sisters on the battery degradation chart, or get a quick estimate with the battery health estimator.

Single cars reported by owners and testers (n=1)

9 UK Car360 AVILOO certificates print both the independent SoH and the car's own BMS figure (often within about 1–2 points). Other rows are owner OBD readings, VW workshop tests, DEKRA, Hungarian AVILOO and forum reports. They show the spread, not an average. Every row is also on the ID.4 data page. Tested a UK ID.4?

6. Battery replacement cost (UK)

We have not found a verifiable, dated UK price for a new ID.4 battery from Volkswagen, so we don't quote one. Inside the warranty, a battery below 70% capacity is Volkswagen's to repair or replace (Volkswagen UK). For an older, higher-mileage car outside cover, get a written quote from a VW dealer or an EV battery specialist before you buy. General UK figures are in our EV battery replacement cost guide.
