📖BYD Tang I: pioneering high-performance hybrid SUV demanding diligent mechanical care

BYD Tang I (2015-2018)

The original Tang served as BYD's groundbreaking performance statement, combining a turbocharged petrol engine with dual electric motors to deliver supercar acceleration in a full-size SUV. Maintaining this potent machine requires comprehensive BYD Tang maintenance, focusing on high-load powertrain cooling and transmission durability.

Beneath the bonnet sits a 2.0-litre turbocharged petrol engine paired with a six-speed dual-clutch gearbox and an intelligent electric all-wheel-drive system. The engine features a robust timing chain valvetrain, while multiple liquid cooling loops independently regulate engine block, turbocharger, inverters and traction battery temperatures.

When shopping for a Tang I, test the DCT transmission under both gentle crawling and hard acceleration to check for clutch slip or shudder. Scrutinise service records for cooling system maintenance and frequent oil changes, inspect suspension bushes and brake pads for accelerated wear from high mass, and check battery charging consistency.

Owner notes

The reassuring points, known weak spots and deadlines you should not let slip.

Reassuring points

Reliability
  • Astonishing straight-line acceleration and dual-motor all-wheel-drive traction in a practical SUV.
  • Durable timing chain valvetrain avoiding the scheduled replacement associated with rubber cambelts.
  • Spacious five- or seven-seat cabin with generous standard equipment and leather appointments.

Chronic weak spots

Keep an eye on
  • Dual-clutch transmission wear: inspect transmission fluid condition and test for low-speed clutch judder.
  • Multi-loop cooling system: check all coolant reservoirs, electric water pumps and hoses for leaks or seepage.
  • Brake disc and pad wear: heavy kerb weight and immense power place high demands on the mechanical braking system.
  • Traction battery pack cell balance: scan high-voltage pack with diagnostic tools to verify uniform cell voltages.

Critical deadlines

Do not miss
  • Engine oil and filter change: renew 5W-40 fully synthetic engine oil every 7,500 km or 12 months.
  • Dual-clutch gearbox fluid service: drain and refill DCT transmission fluid every 40,000 to 60,000 km.
  • Cooling system flush: drain, flush and refill all coolant circuits every 40,000 km or 24 months.
  • Brake fluid service: flush DOT 4 hydraulic brake fluid every 24 months or 40,000 km.
