What we do

Four specialist bench services

Everything is done in-house on professional bench programming equipment — your unit is read, worked on and verified before it goes back in the post.

ECU & Module Cloning

Full data transfer from your failed unit to a matching donor — immobiliser data, coding and adaptations included where supported. The donor becomes your car's unit: refit and drive, no dealer programming in most cases.

  • ENGINE ECU
  • DSG / TCU
  • BCM
  • FEM / BDC
  • BCM2
  • EZS
from £65

Module Repair & Data Recovery

Firmware and EEPROM-level repair of common failures — BMW/MINI FRM3 modules killed by a flat battery, corrupted memory after jump starts, dead clusters and mechatronic data recovery.

  • FRM3 REVIVAL
  • EEPROM FIX
  • DQ200 DATA
  • CLUSTER RECOVERY
from £40

SRS Crash Data Clearing

Your original airbag module wiped of stored crash events and returned fault-free — for vehicles undergoing professional accident repair. OBD one-click on many brands, bench service on the rest. Keeps your original coded unit.

  • OBD & BENCH
  • 70+ BRANDS
  • ORIGINAL UNIT KEPT
from £45

48V Hybrid Battery Repair

Crash-locked or deep-discharged 48V mild-hybrid lithium batteries reset, recharged and cell-balanced — BMW, Audi, Mercedes and Volvo. A fraction of the £1,500+ dealer replacement cost.

  • BMW MHEV
  • AUDI
  • MERCEDES
  • VOLVO MVBM
from £150
Supported units

What we can clone, repair & reset

Search by ECU model, part family or vehicle make. This is a working list of the platforms our bench equipment supports — if yours isn't shown, send the part number anyway and we'll confirm, usually within the hour.

Nothing matching that — try a shorter search, or send us the part number.
Not listed? Coverage grows with every software update and new platforms are added monthly. Message the full part number printed on the unit's label and we'll check it against the current supported list before you post anything.
48V mild-hybrid

48V battery reset, recovery & repair

After a collision — or a long period standing flat — the 48V lithium battery's management system locks itself and the car won't start. Dealers only offer a new battery. We reset the stored crash/fault lock at board level, recharge the pack to its rated voltage and balance the cells.

BMW 48V

Battery
G-series MHEV — 320d/330d, 520d, X3, X5 & more
Crash-locked or deep-discharged 48V starter batteries revived by direct BMS programming. Fault memory cleared, pack recharged and tested.

Audi 48V

Battery
A6 · A7 · A8 · Q7 · Q8 · SQ7 (4N0915105 / 4M0915105)
BMS reset with crash data cleared, recharge and cell balance on the bench — the common fix for "electrical system" warnings and no-start after accident repair.

Volvo 48V

Battery
XC60 · XC90 · S/V90 B-badge mild hybrids
MVBM / IVBM modules with stored collision faults (e.g. B1652) reset without breaking the case open — metal or plastic housings.

Mercedes 48V

Battery
EQ Boost models — C/E/S-Class, GLE, CLS
48V BMS crash and fault locks reset on the bench on supported units — send the battery label part number for confirmation first.

Symptoms we fix

  • Car won't crank after accident repair — 48V battery fault stored
  • "Electrical system malfunction" / drivetrain warning after a collision, even a minor one
  • Battery discharged flat after the car stood for weeks — BMS refuses to wake
  • 48V battery replacement quoted by the dealer at £1,500–£3,000+

What we do

  • Pack safely de-energised and BMS read directly on the bench
  • Stored crash events and fault locks cleared from the controller
  • Pack recharged to rated voltage and cells balanced
  • Tested, resealed and returned tracked & insured — physically damaged cells are reported before any work, not repaired
Simple process

How it works

Get a quote

Send the part number and fault description by the form below, WhatsApp or eBay message. We confirm coverage and price before you post anything.

Post or drop off

Tracked post to our Newport, Shropshire workshop (TF10) — or drop off locally. For cloning, send both your original unit and the donor.

Same-day bench work

Your unit goes on the bench the day it arrives in most cases. Data is read, transferred or repaired, checksum-corrected and verified before it comes off.

Plug & play return

Tracked return post, usually next working day delivery. Cloned units refit and start without dealer programming in most cases — fitting notes included.

Questions

Frequently asked

Both units — your original and a donor with the same part number. The original must have been communicating before it failed (that's where your car's data lives). Send us both part numbers first and we'll confirm they match before you post anything.

In most cases, yes. We transfer the complete dataset — including immobiliser data, coding and adaptations where the platform supports it — so the car accepts the donor exactly like the original. Where a platform needs an extra step after fitting, we tell you upfront and include fitting notes with the return.

Yes — reusing the original SRS module is a normal part of professional accident repair, once every deployed component (airbags, pretensioners, sensors) has been replaced. We return your module cleared and fault-free; the vehicle's SRS system must then be checked with diagnostics after refitting. We don't support using this service to conceal accident history.

No. Cluster and body module work is a data transfer that preserves the vehicle's original recorded mileage on the replacement unit. We do not offer mileage alteration.

Most units are worked on the same day they arrive and posted back tracked the same or next working day. 48V battery jobs can take an extra day because of the charge and cell-balance cycles.

We contact you before going any further and talk through the options — usually sourcing a donor for a clone instead. Water-damaged or burnt units are always inspected and quoted separately before any work starts.
