Comprehensive Volkswagen ECU Repair Coverage

We support all major electronic systems in Volkswagen vehicles, ensuring expert repair across the board.

Volkswagen Engine ECU Repair

Your engine ECU controls essential functions for starting and running your vehicle. Common issues include:

  • Hard or no-start conditions
  • Misfires or rough idling
  • Faulty diagnostics communication
  • Electrical or software failure

Our technicians repair these problems quickly and affordably, helping you avoid costly replacements.

Volkswagen ABS Pump Repair

A faulty ABS pump can reduce braking safety. Watch out for:

  • ABS or ESP warning lights
  • Brake pressure sensor errors
  • Inactive pump motor
  • No communication with diagnostic tools

We repair Bosch, TRW, and ATE ABS systems found in many Volkswagen models.

Volkswagen Body Control Module (BCM) Repair

The BCM manages critical functions like central locking and electric windows. When it fails, you might notice:

  • Non-working locks or windows
  • Constant battery drain
  • Immobiliser faults
  • Water-damaged circuitry

Repairing the BCM often restores multiple systems at once.

Volkswagen Instrument Cluster Repair

A damaged instrument cluster affects visibility and safety. We fix:

  • Blank or flickering displays
  • Dead pixels or dim backlighting
  • Incorrect gauge readings
  • Non-functional warning lights

Our repairs eliminate the need for reprogramming, saving you time and money.

Volkswagen Gearbox ECU & Mechatronics Repair

Transmission problems can often be traced to the ECU or mechatronic unit. Look out for:

  • Gearbox stuck in limp mode
  • Harsh or delayed shifting
  • No drive or reverse
  • Faulty communication with the TCU

We’ll diagnose and repair the unit to restore smooth gear changes.

Volkswagen Airbag Module Repair

An SRS or airbag light usually means internal faults or crash data storage. We can help by repairing:

  • Stored crash data
  • Communication failures
  • Water damage
  • Internal circuit issues

Most repaired units are plug-and-play with no coding needed.

Volkswagen Electric Power Steering (EPS) Repair

EPS faults affect both safety and steering performance. Common signs include:

  • Heavy or unresponsive steering
  • EPS warning lights
  • Loss of power steering assist
  • Motor or torque sensor failure

Each unit is rigorously tested before it’s returned to you.
