Hi all, I have recently purchased an Audi A3 2. After the service they noticed that there was a Whining noise coming from turbo charger and said a possible new turbo may be required. They also stated that both the Intercooler o'ring seals were leaking. My question is would fixing the intercooler seals fix the problem with whining noise from the Turbo? Has anyone else had this issue? What other options do I have? I am new to Audi TDI's. A turbo repair can make your turbo like new or as good as a new one. The turbo is a seperate issue and the o-rings on the intercooler would do diddly squat to silence the whine. Fixing leaking seals won't solve the turbo problem if there is one. Did you purchase privately? If not get the dealership that sold the car to you to rectify the issue. If you purchased privately then you could get a refurbished turbo from one of the companies who do it professionally Turbo Dynamics, Turbo Technics and it will cost you much less than what Audi are quoting you. Good luck. SAiLOApr 23, Thanks, I purchased through a dealer albeit a not well known one. The fact they said possibly a new turbo may be required makes me want to get a second opinion. I am taking my car to an Audi specialist at the weekend and will ask them to check it. Go back to the dealer who sold you the car and demand for it to be fixed. Show them paperwork from audi and explain that if the turbo fails repairs will be much more costly. Will do. The car is under warranty but not sure if the Turbo is actually covered. Will see what they say. I have a similar issue with my A3. I thought it sounded strange, I have had many diesels in the past and never sounded like this, almost like dump valve noise when the boost starts to kick in.

Installing this car part improves speed and performance, but a faulty turbo can lead to expensive repairs. There are some warning signs that indicate that it is time to replace or repair a turbocharger, which can help car owners to avoid the time and expense of severe damage to the vehicle. There are a variety of symptoms that are commonly associated with turbocharger failure in cars. Carefully analysing the performance of the vehicle while you are driving helps to spot irregularities and diagnose turbo issues by your self. One of the most significant symptoms of a failing turbo you should notice is lack of overall power. The car may not accelerate quickly or produce the usual amount of power while on the road. When you are driving a car with a failing turbo, you may notice that your car is slow to respond and does not reach its optimum speeds as rapidly as before. An excessive amount of exhaust fumes or grey smoke expelled from the exhaust pipe may be a sign that it is time for a new turbocharger. A crack in the turbo housing can cause oil to leak into the exhaust system, which produces irregular gases. In many instances, the engine sensor detects a failing turbocharger, triggering the check engine light on the dashboard. An illuminated check engine light may be an indication that further inspection is necessary to determine whether a repair or replacement of the turbo is required. Some of the turbochargers, more likely sports cars, have a boost gauge, which displays the amount of boost that the turbo is producing. If your car is one of those, then you can just look at the boost gauge to determine if the turbo is creating the right amount of boost and if it is rising much slower than usual, a replacement turbocharger may be necessary. If a turbo is failing, it may produce a noise when the boost is running. The noise comes directly from the engine and sounds like a loud siren or shriekwhich tends to get louder as the problem worsens. Some factors can be the cause of a failing turbo, and a thorough examination and diagnostics are often necessary. There are a few common issues that may contribute turbocharger damage and eventually failure. Small particles or objects, such as rocks or dirt, can enter the turbocharger through the turbine or compressor inlet, especially if the air filter fails to catch debris while the car is in motion. If this occurs, the build-up of debris can cause compressor wheel abrasion or damage the turbine blades, diminishing the performance of the turbo. Cracks or faulty seals between the engine and the compressor mean that the turbocharger has to put much more effort into building pressure and forcing air into the engine. While clean oil offers the turbo a fresh supply of lubrication, oil that contains an abundance of contaminants can lead to turbo damage. Failing to change the oil or the oil filter regularly can cause the build-up of carbon deposits, which prevents the turbocharger from working correctly. Even with proper maintenance and care, a turbocharger endures wear and tear over time. First of all, you can check if your turbo really blew up. You can take the intake off from the turbo and check your shaft play to be for sure that it blew up. I would say it would be fine to drive on if you have to, but it would be a lot safer to call a recovery in order to move your car to another place. But you can unhook the linkage from the WG activator, then use a wire to hold the linkage to keep the WG open if you have to drive it for few miles. In this condition and set up you have to be very gentle with your car. And do not drive it for a long up to a miles. As well anytime you are driving vehicle with a blown turbo you should keep an eye on your engine oil level. What often happens is that when a turbo fails, it is the oil seals on the rotor shaft that let go. This allows engine oil to be drawn into the inlet tract and the engine will feed off its own oil.

A turbocharger makes use of the used exhaust gases and forces it through the turbo that acts as an air compressor. The additional air produced from the turbo gets pushed into the cylinder that allows for more fuel to be burnt. Due to environmental issues, large engine cars are being replaced with smaller engine turbocharged cars that are able to match the performance. However, does this mean more trouble? Turbos are a great way to improve the performance of yours car, however there are many common turbo problems that you should be wary off before buying a turbocharged car. Before you point all fingers at your turbocharger, you will want to ensure that the car has good all round health. For example, a faulty EGR can cause excessive exhaust smoke and poor acceleration if blocked. Likewise when you have a blocked DPFit will often cause the car to go into limp mode or whilst going through regeneration of the DPF, there could be excessive smoke. Its important to know the reason why the turbo failed because you may fit a new or refurbished turbo that could fail through an underlying fault. Below are some of the main reasons for turbos to fail:. Even the smallest cracks in one of the pipes coming too and from the turbo can cause issues. If you have diagnosed that your turbo has broken, you will be thrown into the whether you should invest in a new or reconditioned turbo. Both will fix the car and be backed up with warranties in case the turbo breaks again, but whats the best solution? A brand new turbocharger can be bought fairly cheaply and fitted by yourself or a mechanic. As its new, you will have peace of mind that it should last anothermiles, however you will be paying more than a reconditioned turbocharger. A reconditioned turbo is where a specialist will strip the turbocharger to each individual turbo part such as the compressor housing and wheel, turbine housing and wheel, bearings and more. Worn parts will be replaced and the turbo bearings and seals will be replaced with new parts. Other than a loss of power, the noise in which a turbo will make will give you a strong indication of its health. A turbocharger will make good and bad noises but with regards to the bad noise, it is best described as a police siren. Once your turbo has reached this stage, you should really be looking for a replacement. The police siren noise is usually caused by damaged turbines or missing blades. If you are wondering what the police siren noise from a turbocharger sounds likes, view the below video. A blow off valve often called dump valve is located between the turbo compressor and the throttle. As the turbo is on boost, the intake system will become filled with pressurized air from the turbo compressor. Blow off valves will release this pressurized air and makes a desirable hissing noise.

Strange whining noise when boosting!!! Turbo going bad??

User Name Remember Me? After I got home, I let it idle and tried to locate where the sound was coming from. It's definitely coming from the rear of the engine compartment and narrowed it down to the EGR valve or the turbo. The turbo was still building boost but the sound go louder with more boost. Aside from the sound, it drives amd runs fine. Has anyone experienced this? What are the symptoms of a turbo going out? Do they go out slowly or suddenly? Would anything inside the EGR cause this? Lastly, if the exhaust is cracked near the turbo, would it make the same noise? Got Bearings? Find More Posts by Got Bearings? Take a short length of garden hose. Use it like a stethoscope. That should help you determine which it is. Yeah, I plan to to that when I get home tonight. And does anyone know what the symptoms are of a blown turbo or a turbo going out? I'm very new to TDI's. TDI s : '01 Bora and '97 A4 1. Symptoms of a blown turbo will be smoke lots of it! If you don't have boost leak check your exhaust side. Maybe your flange has backed off of the turbo outlet. I'd imagine a crack in your exhaust may sound like a high pitched squeel but have never had that happen to me. My bet is it's something post turbo. Last edited by DbLog; July 27th, at
