Plan d’maintenance BYD S7

The S7 elevated BYD's SUV line-up into genuine seven-seat versatility, offering a significantly higher level of technology, cabin refinement and turbocharged punch. Keeping this capable family hauler in top mechanical shape requires diligent BYD S6/S7 maintenance, particularly regarding powertrain cooling and transmission servicing.

Under the bonnet, an in-house 2.0-litre turbocharged petrol engine drives through a wet six-speed dual-clutch gearbox, backed by an all-wheel-drive system on higher trims. Unlike earlier naturally aspirated engines, it relies on a robust timing chain and an uprated high-pressure cooling system engineered to cope with laden motorway journeys.

When inspecting a used S7, test gear selection in slow traffic to confirm that the DCT engages smoothly without low-speed hesitation. Examine rear dampers and brake pads for accelerated wear from heavy passenger loads, inspect the air conditioning compressor for leaks, and ensure regular oil changes have protected the turbo bearings.
