Mercedes-AMG Mild-Hybrid Repair London | Mobile Mechanic & Diagnostics

🔧 Mercedes-AMG Mild-Hybrid Models – Mobile Repair & Servicing in London

Expert mobile support for high-performance AMG models with 48V mild-hybrid systems.


⚡ What Are Mild-Hybrid AMGs?

Modern AMG models now use EQ Boost – a 48V mild-hybrid system integrated with the starter-alternator and turbocharged petrol engines. This setup enhances acceleration, improves efficiency, and supports electrical components like electric superchargers and active roll systems.

We bring specialist tools and experience straight to your home, workplace, or roadside – no recovery truck or dealership visit needed.

⚠️ Common Mild-Hybrid AMG Faults

These aren’t your average Mercs. When they go wrong, you need proper diagnosis—not guesswork:

  • EQ Boost / BSG Failures – warning lights, start-stop issues, battery drain

  • Turbo Lag or Misfires – especially on the 2.0L AMG variants with electric assist

  • 12V/48V Auxiliary Battery Errors – causes warning lights and limp mode

  • Drive Unit Software Faults – on 63 S E Performance models (rear motor issues)

  • Overboost & Underboost Errors – often related to hybrid torque integration

  • Gearbox Adaptation / Harsh Shifts – requires reset via AMG-specific parameters

  • Active Exhaust Flap or Ride Control Faults – common on GLE/GLC/GT models

  • Cooling System Warnings – high temp on electric turbo circuit or rear motor

  • Charge Air Cooler or Intercooler Pump Issues
