Yes. We use the same XENTRY diagnostic system as Mercedes-Benz authorised dealers. This includes SCN coding, flash programming, guided fault finding and all module live data.
Yes. AMG limp mode is triggered by the DME ECU when critical parameters are exceeded. Common causes: turbocharger overboost, cam phaser fault, transmission overtemperature, or a cylinder head temperature sensor fault. XENTRY identifies the exact trigger.
Yes. We carry high-voltage safety certification and the XENTRY EQ module for the EQ series. Battery health, thermal management and inverter diagnostics are within our capability.
Weak airflow, warm air, or AC odours point to system faults. Hallmark diagnoses and repairs every AC component — compressor, condenser, evaporator and controls.
Hard starting, dashboard warnings, or sudden electrical failures are often battery- or charging-related. We test and replace with the correct OEM-spec battery.
Soft pedal, vibrations during braking, warning lights, or longer stopping distances indicate imbalance in the braking system. Full circuit inspection and OEM-spec restoration.
Surface contamination, swirl marks, and oxidation diminish your vehicle's finish. Our multi-stage detailing process restores gloss and protects paintwork to showroom condition.
Ceramic coating bonds to the paint surface at a molecular level, delivering 9H hardness, hydrophobic protection and UV resistance lasting up to 5 years.
Overheating, coolant loss, warning messages, or unstable temperature readings indicate cooling system failure. Full circuit diagnostics and pressure testing restore thermal management.
Paint protection film guards against stone chips, road debris and abrasion. Vehicle wrapping allows colour change or branding without permanent paint modification.
Loss of power, warning lights, abnormal noise, overheating, or rough running are signs the engine is no longer operating within designed limits. Factory-level diagnostics before any mechanical intervention.
