C sedan • Gasoline/dCi/EV; CVT/EDC/MT

Research focus: verify platform/generation, powertrain/energy/driveline and market-specific application identity against manufacturer/source records before applying parts, service procedures or chronic-fault claims.

System map

• Evaluate fuel supply, rail target/actual pressure, injector balance, charge-air path and EGR/DPF/SCR in the same event capture.
• CVT, D-CVT, IVT and e-CVT are not the same mechanism; identify belt/chain, planetary, motor-generator and hydraulic architecture.

Measurement and verification sequence

1. Capture low-pressure supply, rail target/actual, MAF/MAP, boost and exhaust temperature during crank and load.

Misdiagnosis traps

• Wrong fluid/procedure or transmission-family identity distorts fault and fitment diagnosis.

Variant-specific system split

• Fuel path is separated into low-side supply → high-pressure pump → rail → injectors; air path into MAF/MAP → turbo control → intake manifold.
• For DCT/DSG, TCU-mechatronics, K1/K2 clutches, actuator/line pressure and input/output speeds are evaluated together.
• CVT belt/chain-pulley architecture is not conflated with e-CVT planetary/motor-generator architecture.

Freeze frame / live data

• Freeze frame: first/last fault time, RPM, load, vehicle speed, system voltage, core temperatures and companion DTCs.
• Live data: rail target/actual, low-side supply where supported, MAF/MAP, boost target/actual, EGR command/feedback.
• Aftertreatment: DPF differential pressure, soot/ash calculations, EGT chain, NOx in/out and SCR/DEF dosing enable.
• Driveline: input/output speeds, commanded/actual ratio, clutch/TCC slip, fluid temperature, actuator/solenoid command and adaptations.

Root-cause split

• If rail pressure is low, separate low-side supply from high-pressure generation: when physical low-side supply is healthy but rail cannot follow target, regulation/pump/injector-leakage branches gain weight.
• For low boost, do not jump to turbo replacement: separate MAF/MAP plausibility, charge leak, VGT/wastegate command and exhaust backpressure at the same load point.
• For DCT harshness/slip, separate TCU command from clutch slip and actuator/hydraulic response; adaptation result alone does not prove mechanical wear.
• For CVT ratio faults, identify the architecture first; e-CVT motor-generator power split and belt/chain CVT hydraulic-pulley faults do not share the same diagnostic tree.

What should be verified first?

Model name alone is insufficient. Do not generalize parts fitment, chronic issues or service procedures until production period, market, platform/generation, powertrain, transmission and controller identity are matched.
