Turbos are most commonly associated with diesels and high performance vehicles but are becoming more and more common due to the improvement they have on engine efficiency. A turbo intercepts waste gases leaving your vehicle before they exit through the exhaust, transfers this energy through one turbine to another situated in the air intake system and sends air through to your engine faster, thus improving engine efficiency and power.
A turbo part failure usually denotes an additional fault within the vehicle which requires investigation. These additional faults are known as turbo ‘killers’ and may mean costly repairs are needed to bring your vehicle back to good working order.
We understand the importance of having all the information available to you before you make a decision on a possible high value repair to your vehicle. In light of this, we have developed a process by which we can inform our customers of the problem, possible causes and the cost of the repairs before they decide how to move forward.
We will perform a diagnostic check on the vehicle which consists of using the symptoms described to pinpoint exactly what has caused the turbo failure. This diagnostic will allow us to judge the extent of the issues at hand. Following this the customer then has the following options:
Whatever your motoring requirements, we aim to cater for you. If you have a concern relating to your vehicle or would simply like to discuss vehicle maintenance call your local autocentre for free, friendly, no-obligation advice.

Most road vehicles utilise an internal combustion engine which produces a series of small explosions within a confined chamber which, in turn, forces the physical movement of components to create drive. For combustion to occur, oxygen is required which is drawn into the system and then exported through your exhaust. If the movement of air is quickened, the engine is then able to produce more power: this is the basic concept of a turbo.
The turbo itself is made of two turbine connected by one shaft. One turbine works with gases exiting from the engine through the exhaust while the other is involved with the air entering through the intake system. The gases exiting the engine spin one turbine at speeds of up to 250,000 rpm and temperatures of up to 900 degrees. These gases continue through and out of the vehicle through the exhaust.
The turbines are connected by a shaft and so the movement of the exhaust turbine caused the other to move. The other turbine is connected to the air intake system and increases the speed at which air is fed to the engine. This increase in the flow of air improves engine efficiency and power.
In most cases, the turbo itself does not fail on its own but because of another problem with the vehicle. The problems that can impact the turbo are known as the turbo 'killers' and can be categorised into 4 main areas:
Although turbo failure can be unavoidable, it is advised that you have your vehicle serviced annually and the oil and filter changed to ensure that the oil does not become contaminated and the engine has enough lubricating oil to function.
