Mercedes-Benz’s EQ range brings the brand’s legendary engineering standards to the electric vehicle world. From the executive EQS saloon to the compact EQA and the popular EQC SUV, Mercedes EQ vehicles feature high-capacity battery systems built to exacting standards — and when faults occur, they require specialist expertise to diagnose and repair correctly.
At EV Repair Centre, our high-voltage certified technicians have deep experience with Mercedes EQ battery architecture, the MBUX vehicle integration system, and Mercedes’ proprietary thermal and energy management technology. We provide Mercedes EV owners across Dublin, Kildare, and throughout Ireland with expert, cost-effective battery repair that delivers lasting results.
If your Mercedes EQC, EQE, or EQS is delivering less range than its rated figures, cell degradation within the battery pack is the most common cause. Our cell-level diagnostics identify the exact modules causing the issue — enabling targeted repair rather than costly full-pack replacement.
Charging issues on Mercedes EQ vehicles — including slow charging, failed sessions, or DC rapid charging not activating — can stem from OBC faults, BMS calibration errors, or cell imbalances. We carry out comprehensive charging system diagnosis and repair.
Mercedes' BMS manages cell balancing, charging limits, thermal protection, and power delivery. BMS faults can cause warning lights, sudden power reductions, or incorrect state-of-charge readings. Our technicians diagnose and repair BMS issues across the full Mercedes EQ range.
Mercedes EQ batteries use a sophisticated thermal management system that is critical to battery longevity. Faults in cooling pumps, heat exchangers, or thermal calibration can cause premature degradation. We service and repair these systems to protect your battery investment.
