Automotive Electronic Module Repairs

Modern vehicles rely on multiple control modules. When one fails, replacement can be expensive, hard to source, or require coding. DRG Auto inspects and repairs modules at component level where practical.

ECU / ECM Repair

ECU and ECM faults are our most prominent auto electronics repair area. We inspect engine control units for power faults, communication failures, corrosion, damaged tracks, failed components and known module faults.

  • No communication with ECU
  • No start or intermittent start faults
  • Injector, ignition or sensor circuit faults
  • Water damage and corrosion assessment
  • Capacitor leakage and board contamination
  • Track, via and component-level repairs

ABS / ESP Module Repair

ABS and ESP modules can fail internally, causing warning lights, communication faults, wheel-speed signal issues, or intermittent braking system errors.

  • ABS warning light diagnosis
  • ESP / traction control module faults
  • Communication and internal circuit faults
  • Connector and bond wire issues
  • Board-level inspection under magnification
  • Module resealing after repair where required

TCU / TCM Repair

Transmission control modules can cause shifting faults, limp mode, no communication, solenoid control problems or intermittent gearbox behaviour.

  • TCU / TCM no communication faults
  • Transmission limp mode electronics checks
  • Connector and internal board inspection
  • Power, ground and control circuit assessment
  • Corrosion and liquid damage checks
  • Repairability advice before proceeding

Other Vehicle Control Modules

We also inspect other automotive computers and electronic modules where component-level repair is practical.

  • BCM body control modules
  • EPS electric power steering modules
  • Instrument clusters and display faults
  • Infotainment and head unit faults
  • Air suspension control modules
  • Diagnostic scanner tablet repairs

DRG Auto Location – Lambton Quay Wellington

DRG Auto operates from our Lambton Quay store in Wellington CBD. This is the preferred drop-off and enquiry point for automotive electronic modules, ECU repairs, ABS modules, TCU modules and diagnostic scanner repairs.

DRG Auto at Device Repair Guy Lambton Quay

148 Lambton Quay, Wellington CBD
Phone: 027 531 0155

Bring or send automotive electronic modules to our Lambton Quay team. Please include your contact details, vehicle details, module part number if available, and a clear description of the fault or diagnostic code.

What to Send With the Module

Accurate fault information helps us assess the module faster and avoid unnecessary testing.

  • Vehicle make, model, year and engine
  • Module type: ECU, TCU, ABS, BCM, EPS or other
  • Part number and photos of labels
  • Diagnostic trouble codes where available
  • Symptoms such as no start, no communication or warning lights
  • History of water damage, jump-start, battery or alternator faults

How DRG Auto Module Repair Works

We treat each module as an electronic fault-finding job. Some modules are repairable, some are not practical to repair, and some require vehicle-side faults to be ruled out first.

01

Fault Information

Send us the module details, vehicle information, fault symptoms and diagnostic codes. More detail helps us assess the likely repair path.

02

Bench Inspection

We inspect the module under magnification and check for corrosion, cracked joints, failed components, damaged tracks, power issues and signs of previous repair attempts.

03

Repair Assessment

We confirm whether repair is practical and quote before proceeding where possible. Some cases require staged diagnostics before a final answer.

04

Repair & Return

If repair is approved, we carry out component-level work and return the module for refitting and vehicle-side testing by your workshop or technician.

Common Automotive Computer Faults We Inspect

Automotive module faults often appear as vehicle symptoms, but the root cause may be inside the module, in the wiring, or elsewhere in the vehicle. We focus on the electronic module itself.

No Communication

A scanner may fail to communicate with the ECU, ABS, TCU or BCM due to internal power supply faults, damaged communication transceivers, corrosion or board-level damage.

No Start or Intermittent Start

ECU power faults, relay driver issues, immobiliser-related problems, injector or ignition driver faults, and internal board damage can all contribute to no-start symptoms.

Warning Lights and Limp Mode

ABS, ESP, transmission and engine warning lights may be caused by module faults, but vehicle-side wiring and sensor faults should also be checked before module repair.

Water Damage and Corrosion

Moisture ingress, leaking capacitors, battery acid, poor sealing and previous repair attempts can cause corrosion, track damage and intermittent faults.

Why Repair Automotive Electronics Instead of Replacing?

Replacement modules can be expensive, hard to find, require coding, or create delays. Repair can preserve original programming and reduce unnecessary module replacement when the fault is repairable.

01

Keep the Original Module

Repairing the original ECU, ABS or TCU can avoid coding, immobiliser or compatibility issues that may come with replacement modules.

02

Reduce Replacement Cost

Component-level repair can be more economical than sourcing a new or used module, especially for rare or back-ordered vehicle computers.

03

Useful for Workshops

Mechanics and auto electricians can use DRG Auto as an electronics repair partner when the vehicle-side diagnosis points to a failed module.

04

Board-Level Experience

Our background in logic board repair, microsoldering and device electronics carries across to many vehicle modules and diagnostic tools.

Auto Electronics Repair FAQs

Do you repair ECU and ECM modules?

Yes. DRG Auto inspects and repairs many engine control units at component level, including power faults, communication faults, corrosion, capacitor leakage and board damage.

Do you repair ABS and ESP modules?

Yes. We inspect ABS and ESP control modules for communication issues, internal circuit faults, connector faults, bond wire issues and board-level damage.

Can you repair TCU or TCM transmission modules?

We can inspect TCU and TCM modules for no communication, power faults, corrosion and internal board issues. Repairability depends on the module construction and fault type.

Should I send the whole car or just the module?

In most cases we inspect the electronic module itself. Mechanics and auto electricians usually remove the module and send or bring it to DRG Auto at Lambton Quay with fault notes and diagnostic codes.

Can every automotive computer be repaired?

No. Some modules are sealed, badly damaged, coded in a way that makes replacement more practical, or have vehicle-side faults outside the module. We assess repairability before proceeding where possible.
