A faulty turbocharger in the Nissan Juke causes loss of power, whining noises and black smoke from the exhaust, usually due to wear or problems with the oil supply. Many owners of this compact SUV have to deal with this. Know what is going on and how to prevent further damage.
Symptoms of a failed turbocharger
When the turbocharger on your Nissan Juke fails, you notice it straight away. The most striking sign is loss of power while accelerating. You press the accelerator pedal, but the car responds sluggishly. In addition, you often hear squealing or whistling noises from the engine bay. These sounds are caused by damaged bearings or air leaks in the turbo system.
Black or blue smoke from the exhaust is another important warning sign. This happens when the turbo leaks oil into the combustion system. Your fuel consumption shoots up and you may see oil stains around the turbo. These symptoms occur regularly on Nissan Juke models with the 1.2 DIG-T, 1.6 DIG-T and 1.5 dCi engines.
‘ This accelerates wear and increases the risk of faults. ’
Why your Nissan Juke is losing power
Loss of power due to turbo problems usually has a clear cause. The turbocharger increases the air pressure in the engine, so more fuel can be burned. If the turbo is not working properly, the engine gets less air. The result is that your car feels much less powerful, especially at higher speeds or when pulling away.
On diesel models the particulate filter also plays a role. A clogged diesel particulate filter (DPF) causes increased back pressure in the exhaust system. The turbocharger has to work harder to build up sufficient pressure. This accelerates wear and increases the risk of faults. This problem is particularly common on cars that mainly do short trips, where the filter cannot regenerate properly.
Common causes of turbo damage
Most turbocharger problems in the Nissan Juke are caused by the oil feed line. This narrow pipe supplies oil to the turbo bearing. If this line becomes blocked or damaged, the turbo does not get enough lubrication. The bearings spin at high speed without proper protection and wear out extremely quickly.
Real-world cases show how important this is. Owners report that a new turbocharger failed after just a few kilometres, until it turned out that the oil feed line was blocked. After replacing this line, the system worked normally again. Other causes of turbo damage are:
- Wear due to high mileage
- Loose or split air hoses
- Contaminated engine oil or overdue oil changes
- Foreign objects in the air intake system
- Incorrect driving style with constant high load
How to fix a turbocharger problem
If you suspect turbo damage, have a diagnosis carried out first. A garage will check the turbo and the entire oil system. If the turbo needs replacing, it is important to replace the oil feed line at the same time. This prevents a new turbo from developing the same problems.
Before fitting a new turbocharger, the engine must be prepared. Turn the ignition key without starting the engine. This allows the oil pump to build up pressure before the turbo begins to spin. This protects the bearings during the first start. Also check the air filter and all hoses for damage or leaks.
If oil has entered the exhaust system, the oxygen sensors and catalytic converter can also be damaged. This results in fault codes and extra repair costs. That is why you should always request a full inspection of the exhaust system during turbo repairs.

Preventive maintenance for your turbo
A well-maintained turbo lasts longer. The most important thing is to change the engine oil regularly in line with the service schedule. Always use the correct type of oil specified by Nissan. Contaminated or too thin oil does not protect the turbo bearings properly.
Pay attention to your driving style. Avoid constantly driving at low revs with lots of throttle. The turbo is then under high pressure without sufficient cooling. Regularly do longer trips, especially if you have a diesel engine. This helps keep the particulate filter clean and prevents extra load on the turbo.
Other preventive measures are:
- Replace the air filter on time
- Check regularly for oil leaks
- Let the engine idle briefly after an intensive drive
- Inspect air hoses for splits or loose connections
Which Juke models have turbocharger problems more often
Not all Nissan Juke engines have the same number of turbo problems. The 1.2 DIG-T petrol engine and the more powerful 1.6 DIG-T variant regularly show complaints about the turbocharger. The 1.5 dCi diesel engine is also known for faults in the turbo system.
On older models these problems occur more often due to the higher mileage. If you are considering a used Nissan Juke, ask about the service history of the turbo and the oil feed line. A well-documented service history gives more peace of mind.
Costs of turbo repair
Repairing a turbocharger costs money. Prices vary widely, depending on the engine type and whether you opt for a new or reconditioned turbo. Expect to pay several hundred to well over a thousand euros for parts. On top of that are the labour costs for removal, fitting and checking the system.
Replacing the oil feed line is relatively inexpensive, but must always be done during a turbo repair. If you skip this, you run the risk of facing the same fault again before long. Ask for a detailed quote in advance and have them explain which parts will be replaced.

When to go to the garage
Not sure whether your turbo is still in good condition? Then go straight to a specialist garage. Continuing to drive with a failed turbo often causes more damage to the engine. Metal particles from the damaged turbo bearings can spread throughout the entire engine system.
In acute cases such as sudden loss of power, loud bangs from the engine or excessive smoke, it is better to stop driving. Call in a recovery service. These warning signs indicate serious damage that needs immediate attention.

Frequently asked questions
The most common symptoms of a faulty turbocharger on a Nissan Juke are loss of power during acceleration and squealing or whistling noises from the engine. In addition, excessive smoke from the exhaust and increased oil consumption or oil leakage around the turbo often occur. Higher fuel consumption can also point to turbo problems.
Carry out regular oil and oil filter changes using the specified oil and at the same time check the oil feed line to the turbo for blockages or damage. Have the engine air filter replaced on time and make sure the DPF (for diesel) can regenerate properly by regularly doing longer journeys. Avoid driving under high load at low revs to prevent excessive turbo stress. Watch out for early warning signs such as whistling noises, smoke or loss of power and have these checked immediately.
The costs for repairing a turbocharger fault on a Nissan Juke vary widely, but you should quickly reckon on an amount of many hundreds to well over a thousand euros, depending on the engine type and whether parts are reconditioned or new. The best approach is not only to (have) the turbo itself replaced or reconditioned, but always to check and replace the oil feed line as well to prevent repeated failures. It is also sensible to have the DPF (for diesels) and the lubrication system checked for contamination. Ask a specialist in Japanese or turbo engines for an itemised quote, including inspection of the oil supply and relevant filters.
Yes, on the Nissan Juke certain turbocharger faults occur relatively often, especially on the 1.2 DIG-T, 1.6 DIG-T and 1.5 dCi engines. In particular, problems with blocked or defective oil feed lines to the turbo are reported strikingly often, which can lead to premature turbo damage. DPF blockage on diesel models, which creates extra load on the turbo, also appears to be a known factor on the Juke. As a result, turbocharger problems on this model are highlighted more often than on some other comparable cars.
Watch out for early loss of power when pulling away and a clearly audible whistling or squeaking sound from the turbo that you did not hear before. Regularly check for traces of oil or greasiness around the turbo and pipework, and keep an eye on increased exhaust smoke or higher fuel consumption. If in doubt, have the oil feed line to the turbo checked early for blockage or damage. Regular oil and filter changes using the correct specification help to prevent minor symptoms from developing into a real fault.
