Common Problems with the
2020 Volkswagen ID.3 Mk1

The ID.3 launched as VW's first purpose-built electric car, but early models were plagued by software bugs that frustrated UK buyers. Frozen screens, random warning lights and connectivity failures were common complaints. The mechanical package was excellent — quiet, comfortable and efficient — but the software let it down badly at launch.

What changed for 2020

  • •VW's first MEB-platform electric car
  • •Introduction of the 77kWh battery option for longer range

Common MOT watch-outs

  • !Software bugs causing multiple dashboard warning lights
  • !12V auxiliary battery failures triggering cascade electrical faults

All Known Issues

Software / Infotainment Bugs

ModerateElectrics & Electronics

Early cars suffered from frozen screens, connectivity failures and erratic warning lights. VW has released several OTA updates but some cars need dealer intervention.

Est. Repair Cost: £0 (Software update)
Warning Signs:

Screen reboots, Warning lights, Navigation failure, Bluetooth disconnects

What to Inspect:
  • Confirm software version (v3.0+ recommended)
  • Test all infotainment functions during test drive

12V Battery Causing Cascade Faults

ModerateElectrics & Electronics

The 12V auxiliary battery degrades prematurely, triggering multiple seemingly unrelated high-voltage system errors. A failing 12V battery can make the car refuse to start or enter a fault state.

Est. Repair Cost: £100–£250
Warning Signs:

Multiple warning lights, Car won't start, "Electrical system fault" message, Infotainment resets

What to Inspect:
  • Test 12V battery voltage (should be 12.4V+)
  • Check service history for 12V battery replacement

Door Handle / Locking Issues

ModerateBodywork & Rust

The flush-fitting capacitive touch door handles can become unresponsive or fail to unlock, particularly in cold or wet weather. Mechanical override inside the handle is often needed.

Est. Repair Cost: £100–£300
Warning Signs:

Door won't unlock with handle touch, Must use key fob buttons, Intermittent handle response

What to Inspect:
  • Test all door handles multiple times
  • Check for software updates that address this
  • Test in wet conditions if possible

Suspension Control Arm / Bush Wear

MinorSuspension & Chassis

Front suspension control arm bushes wear prematurely, causing knocking noises over bumps and vague steering feel. The MEB platform places high loads on these components.

Est. Repair Cost: £150–£400
Warning Signs:

Knocking noise over bumps, Vague steering, Uneven tyre wear

What to Inspect:
  • Check for play in front suspension
  • Inspect bush condition visually
  • Listen for knocks on test drive

  • ✓Only consider an ID.3 if it has received software version 3.0 or higher — early versions were severely flawed
  • ✓Test the 12V battery voltage during the test drive — a weak 12V battery causes seemingly random high-voltage faults
