How much does turbo repair cost?

Turbo repairs range from $200 for a boost sensor or solenoid to $1,500-$3,000+ for turbocharger replacement. Early diagnosis of boost leaks can prevent the most expensive repairs.

What causes turbo failure?

Common causes include oil starvation, contaminated oil, foreign object ingestion, excessive heat, and normal wear. Regular oil changes with proper oil are essential for turbo longevity.

P0246

Turbo/Super Charger Wastegate Solenoid "A" High

Moderateturbo

Overview

The P0246 code indicates a turbo/super charger wastegate solenoid "a" high condition has been detected by the PCM. This code relates to the turbocharger/supercharger system that provides forced induction to increase engine power. Issues with the boost system can result in reduced power, poor fuel economy, and potential turbocharger damage if not addressed.

Symptoms

Check Engine Light (MIL) illuminated
Whining or whistling noise from turbo
Turbo lag or surging
Loss of boost pressure

Common Causes

Clogged air filter restricting airflow
Damaged turbo oil supply or return line
Failed turbocharger boost pressure sensor
Worn or damaged turbocharger bearings

Diagnosis Steps

1Connect an OBD-II scanner and read all stored trouble codes and freeze frame data
2Inspect all boost hoses and intercooler piping for leaks or disconnections
3Test the boost pressure sensor with a multimeter or scan tool live data
4Check the wastegate and bypass valve for proper operation
5Inspect the turbocharger for shaft play, oil leaks, or damage

Estimated Repair Cost

$200 — $3,000

Cost varies by vehicle, location, and repair shop. Includes parts and labor.
