The Mercedes GLS uses a 3.0 M256 inline-6 EQ Boost (367 bhp GLS450) and is classified as a suv. Based on our workshop experience with Mercedes GLS in Hyderabad: AIRMATIC air suspension compressor failure — common at 60,000 km. We also see turbo boost loss in vehicles that share similar engine architecture to the Mercedes GLS.
Inspect intercooler pipes and clamps at every service — rubber deteriorates in Hyderabad heat and hose clips loosen from vibration.
