What it means

The turbo pushes extra air into the engine. The computer found the boost pressure wrong or the turbo control not working. The car often goes into limp mode.

What you may notice

  • Much less power (limp mode)
  • Turbo whistling or hissing
  • Black smoke
  • Engine light on

What could be wrong

  1. 1Leaking boost hose or intercooler · Turbo repair or replacement €700–1400
  2. 2Turbo actuator (VNT or wastegate) stuck · Turbo repair or replacement €700–1400
  3. 3Boost pressure sensor reading wrong · Alternator replacement €350–650
  4. 4Control solenoid or its vacuum hose · Vacuum hose or actuator replacement €60–120
  5. 5Worn turbo · Turbo repair or replacement €700–1400

Repair difficulty: Hard

What you can check yourself

Check the boost hoses, especially the joints and around the intercooler. An oily hose points to a leak. Best left to a workshop. It needs a diagnostic tool and experience.

How we fix it

  1. We measure boost pressure on a test drive
  2. We pressure-test the boost hoses
  3. We check the actuator movement and solenoid
  4. We replace the hose or sensor, or repair the turbo
