In my 2009 Audi A4, the turbocharger quit operating. Can the automobile still run without it, and does driving the car harm it? Gabriella
Your turbocharger is a turbine/fan device designed to increase the pressure of the incoming air into the engine. It is powered by the exhaust gases from the engine. The term “forced induction” refers to this pressure boost, which is utilized to increase engine production and efficiency. The simplest way for a turbocharger to fail is with an air leak, which prevents pressure from developing, or with a broken waste gate actuator, which is part of the control system and can result in an under- or over-boost state.
Although the car can still run without a turbocharger, it will perform poorly, and your choice might have far-reaching effects.
Complete failure is imminent if there is a problem with the oil supply or internal parts. Unfortunately, as it fails, the engine will eat all the debris left over from the catastrophic incident, resulting in a complete financial catastrophe.
On this one, you should err on the side of caution and fix the car. This is one of those occasions where looking around for a reasonable price is advised.

Can you operate an Audi with a damaged turbo?
The gist of the response is that you can still operate your vehicle despite a damaged or blown turbo. However, the more engine damage there is and the longer you drive it in this condition, the more expensive the repairs will be. Although the automobile will still be able to move forward on its own, it is strongly advised that you cease driving it and have it towed to a repair shop instead.
Can you operate a vehicle without a turbo?
However, engine failure won’t be far behind if your turbocharger fails, so only continue driving if you really must.
Get your turbo checked by a trained technician as soon as you notice any of the above-listed indications of turbo failure. The problem will worsen (and cost you more) the longer you ignore it.
We may do a diagnostic check at Dowleys Garage to pinpoint the issue and provide advice on any repairs that are required. On weekdays from 8:30 to 5:30 and on weekends from 9:00 to 12:00, our garage is open.
How long may a damaged turbo be operated?
It’s a good idea to stop the car and examine the turbo if you suspect it has blown. The fact that smoke is emanating from the component is very conclusive, but if you’re still not convinced, remove the intake and examine the shaft. You can, in fact, continue to drive without the turbo, although it is likely safer to request a recovery lift.
If you choose to continue driving despite having a broken turbo, detach the linkage from the wastegate activator first, and then use a wire to hold the wastegate open while you travel the required distance to a mechanic. Take it gently on the throttle because the wastegate won’t be able to withstand the full exhaust pressure. If you do decide to drive with a blown turbo, be sure to monitor your oil level and don’t travel more than about 100 miles.
What happens if the turbo doesn’t function?
The components of a failed turbo usually end up in the intercooler along with a lot of engine lubricating fluid. If you do not swiftly stop it, smaller fragments and more engine oil enter the engine. On this oil that has been spilt, the engine can truly “run away.”
Remove the intercooler and ALL intake system tubes, including the airbox, filter housing, and related tubes, if you experience a failure. Clearly clean them. Usually, these parts are what lead to a second, instant failure.
What is the lifespan of a failing turbo?
Turbocharger failure can occur for a number of reasons. The most typical are listed here:
Although turbochargers are developed and engineered to survive for many years, they will ultimately break down like all other car parts. Your turbo should last up to 150,000 miles, or even longer if it isn’t used frequently.
Turbos inject more air into the cylinders of your engine. If there are cracks in the turbo, the pressure required will decrease. Your turbo might have to work harder as a result to provide the necessary turbo boost.
If you do not replace your oil on a regular basis, carbon deposits can accumulate. Every time you have your automobile serviced, it’s crucial to get your oil changed. In addition to protecting your turbo, it offers a host of advantages for the general wellbeing of your car. Mechanical problems can become expensive and bothersome when pollutants are present, even at relatively low levels.
How much does a turbo replacement cost?
I’m glad you love driving your brand-new car. Generally speaking, you should budget a few hundred bucks to fix the turbo.
If the turbo cannot be repaired, a replacement will probably cost between $1,000 and $2,000, but some owners have reported paying as little as $500 and others closer to $4,000.
Nevertheless, the cost to replace a car’s turbo might vary considerably depending on:
- How much damage there is
- The year, make, and model of your car
- The turbo type that was fitted
You should get quotes from a few different companies that specialize in modifications in order to estimate the cost of the repair. You’ll get the best estimate of the cost to fix your car’s turbo by doing this.

What symptoms indicate a failing turbo?
What are the early warning signals of turbo failure and how can you recognize them now that we are aware of the faults?
- Engine caution signs Modern vehicles are built to detect issues like turbo failure, so always pay attention to your dashboard warning lights as they can be indicating that your engine (or your turbo) needs to be checked out.
- power outage
- Your turbocharged car might not be producing as much power as normal. It may be a sign of a problem if it accelerates more slowly than planned or has trouble reaching desired speeds.
- strange noises
- If your turbo has a problem, your engine may make a loud whining sound. If you hear this noise, which has a police siren or dental drill-like quality, it is absolutely worth looking out because it indicates turbo failure.
- smoke from exhaust
- Oil will start to flow out of your exhaust system if the turbo housing has split. When the engine revs after being stationary, blue/grey smoke will then appear more prominently.
- Boost meter
- this informs you of the amount of boost your turbo is making. If your boost gauge isn’t rising as much as it once did, that could be a symptom of a failing turbo.

What occurs if a turbo fails?
A blown turbo’s most typical warning indications are: Your car seems to accelerate slowly and loudly. You have trouble keeping your car moving at high speeds. The exhaust is producing smoke. The dashboard displays an engine failure light.
What results in a turbo failing?
An air pump called a turbocharger delivers air for the engine’s combustion process at a higher pressure and density than outside air. More oxygen content in the turbocharger air enables significantly enhanced combustion, resulting in increased power, cleaner emissions, improved engine torque output, and less pumping losses for better overall performance.
Any flaws in these systems, which are a crucial component of the engine’s cooling, air, fuel, and oil systems, could result in improper turbo operation and even damage.
The three turbo killers
Turbos fail as a result of manufacturing flaws in less than 1% of all cases. The three “turbo killers” of oil starvation, oil pollution, and foreign object damage are responsible for the majority of failures.
More than 90% of turbocharger failures are related to oil, either through oil pollution or oil hunger. Oil starvation is typically caused by clogged or leaking pipelines or by a fitting that hasn’t been primed.
The engine oil has the potential to carry a variety of contaminants into the turbo bearing system and harm it. The most prevalent are fine particles, typically carbon from combustion, and if their concentration rises too much, they act as a very powerful abrasive, gradually wearing down and polishing the running surfaces of the bearing and shaft, widening clearances, and blocking oil feed holes until the oil loses its ability to control the shaft. Typically, this is accompanied by an abrupt rise in noise level, oil leaking past the turbine end seal, which causes oil to burn, and, in cars without a particle filter, significant exhaust smoke.
You should also take into account the following factors because other factors, such as bad driving behavior, can trigger turbo failure:
- Long-term engine idling can cause the turbine to create a vacuum
- Hard acceleration from a cold start prevents the oil from having time to circulate, starving the turbo and engine bearings of oil.
- A hot engine shutdown might result in a buildup of carbon in the turbo, which can cause bearing failure.
- Excessive engine revving, especially in commercial vehicles like on-highway trucks, can result in the turbo overspeeding and overboosting the engine (this can also happen in naturally aspirated engines), as well as oil starvation.
Without proper calibration, a remanufactured unit would have to employ non-original parts, leading to:
- A poor effort
- An early failure
- possible harm to the engine
- The cost of installing a second, “new,” turbocharger
- a lost client.
Turbocharger Troubleshooting
If you suspect a turbo-related issue with your car, halt before you replace it because turbo damage is frequently more of a symptom than a true cause of an issue. A broken fuel injection system, congested or obstructed air filters, a damaged exhaust system, or a lubrication issue may cause a lack of power, a noisy engine, or excessive smoke or oil consumption.
Use the Turbocharger System Diagnostics Guide to facilitate your work because it is crucial to examine all the systems before replacing the turbo.
How frequently should Turbos be replaced?
A superb engineering achievement, the turbocharger increases the engine of your car’s power and effectiveness. Turbochargers, however, are wearing parts and therefore will deteriorate with time. Between 100,000 and 150,000 miles is the typical range at which turbochargers need to be replaced. Your turbocharger could last even longer if you take proper care of your vehicle and get regular oil changes.
To prevent further harm to your automobile and to your pocketbook, have your turbocharger checked as soon as you become aware of a problem. The cost of repairing a turbocharger will significantly increase if action is delayed.
Can I still drive if my turbo blows?
The more engine damage there is and the longer you drive your car with a blown turbo, the more expensive the repair will be. Even if the car will still move if the turbo is blown, it would be far better to stop driving it and have it towed to the shop so the turbo can be fixed or replaced. The engine of the car could sustain greater harm the longer the blown turbo is left unfixed.
