How to check the working condition of the turbocharger

Today, most vehicles in the market are equipped with a turbocharger. Turbo increases engine performance and improves dynamics, reduces fuel consumption and makes transport more environmental-friendly. Using exhaust energy and performing up to 200,000 rpm, the turbocharger operates at extremely high temperatures and enormous voltages. Given the complexity of the device and the extreme operating conditions, it is useful for owners of turbocharged cars to know how turbo works, to be able to assess its condition and to understand when to contact car service.

Symptoms of a possible malfunction

The following symptoms may indicate a possible turbo malfunction:

• power drop and unstable traction
• increased oil and / or fuel consumption
• oil leakage and combustion
• changed colour (white, grey, black) of exhaust smoke
• an unusual sound under the hood

If these symptoms occur, it is advisable to have your turbocharger diagnosed. As these points may also be relevant to problems with other systems and parts in the car, it is advisable to contact a car repair shop for an accurate assessment.

General independent control

Technically competent driver can independently check turbo for the most common faults. If access to a turbocharger is not complicated, it is possible to check its housings for cracks or combustion residues, for complete or damaged wheels and for airtight air duct connections. It is also important to make sure that the turbo wheels do not scratch against the walls of the housings. Deformed blades and scratches on the walls indicate an impermissible play in the shaft, which damages the turbocharger and destroys it very quickly.

Specialist inspection

Turbo is a complex device that requires professional training and equipment for maintenance. Complex diagnostics are performed in car repair shops, where turbo is dismantled and tested under load. Specialists have access to computers for measuring air pressure, diagnostic racks, cleaning and balancing machines. Only professionals with special equipment and original spare parts can pinpoint the cause of the problem and carry out repairs according to the factory parameters, which ensures the proper and high-quality operation of turbo.
