Tesla fault codes

Which fault codes point to the high-voltage battery?

On Tesla, fault codes appear in the instrument cluster and on the central MCU display — tap the red warning triangle at the top of the screen. Codes beginning with BMS can indicate a high-voltage battery fault. When you contact us, please note any visible codes — it helps us identify the right pack faster.

Battery-related codes we commonly see
BMS_A064 BMS_A066 BMS_A079 BMS_A107 BMS_f017 BMS_f018 BMS_f107 BMS_f123 BMS_u018 BMS_u019 BMS_u025 BMS_u029 BMS_w017 BMS_w177

This list is a guide, not a diagnosis — several of these can have other causes. Send us your codes and we'll advise.

A longer second life

Built to last — and to keep cars on the road.

Remanufacturing keeps high-voltage packs out of waste and extends the life of the whole vehicle. Every pack we deliver leaves our line measured and documented, at a high, verified state of health.

Inside the pack

What we remanufacture, component by component

Tesla high-voltage battery pack, opened to show modules and components
1
Battery modules
We test every module for capacity and internal resistance, and rebuild the pack only with healthy, matched modules.
2
BMS — Battery Management System
We test the BMS and confirm it balances every cell and works correctly.
3
Cooling system
We pressure-test the cooling circuit for leaks and confirm it seals.
4
High-voltage connectors
We inspect the high-voltage connectors and contacts, and replace any that are worn or damaged.
5
Casing
We clean, inspect and reseal the housing so the pack stays protected and watertight.
Tesla replacement batteries

Tesla battery replacement — remanufactured, tested and warranted

If your Tesla has lost range, is showing battery-related warnings such as BMS fault codes, or the high-voltage battery no longer charges normally, we supply a remanufactured pack, rebuilt to specification and warranted. We have already remanufactured packs across the full Tesla range — Model S, Model 3, Model Y and Model X — in both Standard Range and Long Range trims, rear-wheel drive and all-wheel drive, from around 55 kWh on Standard Range Model 3 and Model Y up to roughly 100 kWh on Model S and Model X.

Tesla models we remanufacture batteries for

  • Tesla Model S — 70, 75, 85, 90 & 100 kWh (incl. P85, P90D, P100D)
  • Tesla Model X — 75, 90 & 100 kWh
  • Tesla Model 3 — Standard Range / RWD (~55–60 kWh) and Long Range / Performance (~75–82 kWh)
  • Tesla Model Y — RWD (~60 kWh) and Long Range / Performance (~75 kWh)
  • Both rear-wheel drive and dual-motor all-wheel drive

Not on the list? Don't worry — contact us and we'll find the right solution for your Tesla.

Signs your Tesla battery needs attention

  • A clear drop in driving range or usable capacity
  • BMS fault codes shown on the instrument or centre display
  • The high-voltage battery no longer charging to full
  • Battery or high-voltage-system warning messages
Where the swap happens

High-voltage battery replacement is available through our partner workshops across Finland — including Helsinki, Vantaa, Turku, Tampere, Oulu, Rovaniemi and more. No partner near you yet? Contact us anyway — we can help.

We do not recommend single module replacement

Replacing one module creates a voltage imbalance between old and new modules — the battery will fail again shortly after. A full remanufactured pack with matched modules is the correct solution.
