Est. Repair Cost: £600–£1,500
Warning Signs:

AYC or ASC warning lights, Drive mode faults, Pump noise or no response from the system

What to Inspect:
  • Scan for AYC-related faults
  • Inspect the pump area for corrosion if possible
  • Ask whether the pump has been rebuilt or relocated

Warning Signs:

Jerky pull-away, Refusal to select gears, Transmission warning or limp mode

What to Inspect:

Est. Repair Cost: £400–£2,000
Warning Signs:

Heavy rust on rear subframe, Corrosion advisories on MOT history, Fresh underseal without photo evidence

What to Inspect:
  • Inspect the rear subframe and suspension mounts

Buying Tips for 2012–2014 Mitsubishi Lancer Evolution X

  • ✓Manual cars are mechanically simpler; SST cars need proper Mitsubishi SST fluid history and should feel smooth, not jerky or reluctant.
  • ✓Inspect the AYC pump area and rear underbody for corrosion because UK road salt is especially hard on these cars.
  • ✓Be very cautious of hard-used or badly modified examples; track abuse shows up quickly in tyres, brakes, drivetrain fluids and accident repairs.
