5 Signs Your Diesel Pickup's Turbo Might Be Failing

5 Signs Your Diesel Pickup's Turbo Might Be Failing

Adding a turbocharger can improve your pickup's performance by 35%. This can prove crucial for trucks that are carrying or towing large loads, like those used for manufacturing. Boosting engine power can improve performance on existing engines without the need for extensive engine modifications.


However, having a turbocharger on your diesel vehicle also comes with a few additional maintenance considerations. One key component to keep an eye on is the turbocharger itself. Here are five signs that your diesel pickup's turbo might be failing:

1. Unusual noise coming from the engine bay

If you hear an unusual noise coming from your engine, it could be a sign that the turbocharger is failing. The most common symptom of a failing turbo is a loud, high-pitched noise called a "turbo whistle." This noise is caused by air escaping from the turbine housing or compressor wheel.

2. Loss of power when accelerating

If you notice a loss of power when accelerating, it could be due to a problem with the turbocharger. This is because the turbocharger relies on exhaust gases to spin the turbine. If there is an issue with the turbo, it can't generate enough power to spin the turbine, which results in a loss of power.

3. Engine runs rough at idle

If your engine is running rough at idle, it could be a sign that the turbocharger is failing. This is because the turbocharger relies on exhaust gases to spin the turbine. If there is an issue with the turbo, it can't generate enough power to spin the turbine, which results

4. Black smoke coming from the exhaust

Black smoke coming from the exhaust is another sign that the turbocharger might be failing. This is because the turbocharger boosts the engine's power, which can cause the engine to run richer than usual and produce black smoke.

5. Increased fuel consumption

If you notice that your fuel consumption has increased, it could be due to a problem with the turbocharger. A failing turbocharger can cause the engine to run less efficiently, which leads to increased fuel consumption.

6. Your check engine light is on

If the Check Engine Light is on, it could be a sign that the turbocharger is failing. The Check Engine Light can be triggered by a variety of issues, so it's important to have the car checked by a mechanic to diagnose the problem.


If you notice any of these symptoms, it's important to take your pickup to a mechanic to have the problem diagnosed and repaired. Turbochargers are complex systems, and they can be expensive to repair or replace. However, ignoring the problem can lead to further damage, so it's important to take action as soon as possible.

What to do when your turbo fails

If your turbocharger fails, there are a few things you can do to mitigate the damage. First, consult your owner's manual to see if there is a limp mode or safe mode that will limit the engine's power and help prevent further damage. Second, avoid putting too much strain on the engine by avoiding hard accelerations and hills. Finally, take the car to a mechanic as soon as possible to have the problem diagnosed and repaired.

What causes a turbo to break down?

There are a few reasons why a turbocharger might break down. First, the turbocharger relies on oil to lubricate the bearings. If the oil level is low, it can cause the bearings to wear out prematurely. Second, dirt and debris can build up in the turbocharger, causing it to fail. Finally, the turbocharger can fail if it isn't used regularly. This is because the turbocharger relies on exhaust gases to spin the turbine, and if the engine isn't running, the turbine can seize up.


If you have a diesel pickup truck, it's important to keep an eye on the turbocharger. Turbochargers are complex systems, and they can be expensive to repair or replace. However, ignoring the problem can lead to further damage, so it's important to take action as soon as possible if you notice any signs of a failing turbocharger.
