- Dramatic decrease in fuel economy.
Does wastegate rattle affect performance?
The rattle usually doesn’t affect performance, if it does you’re likely to get an underboost code. If you’re tuned you can check your wastegate duty cycle for abnormally high values.
What causes turbo wastegate rattle?
Wastegate Rattle is caused by the wastegate flapper moving around inside the wastegate arm; this movement is usually caused by a worn flapper bush, or the wastegate arm itself is worn. The rattle is presented when the flapper moves around, and makes contact with either the turbine housing, or the wastegate arm itself.
How much does it cost to replace a wastegate?
Depending on your engine setup and ease of accessibility, the turbocharger may need to be removed to allow for wastegate hose replacement, and as such, repair costs can vary from $150 to $500 and up.

If you have faulty wastegate, than you shoud drive very-very moderatly until you change the faulty one. When only one turbo works fine, and the other does not, than the good one has to be work much harder (instead of the faulty one) to provide the given total boost required by the ECU.

This could be caused by many different factors such as low oil levels, low oil pressure, and cooling problems. This is definitely a problem you need to go see your mechanic about – if an engine overheats too much it could cause the bearing and crankshaft to seize completely which becomes very costly to repair.

Carbon buildup on the BMW N54 engine (as well as N55 engine) can become severe over time, almost completely closing off the intake tracts and valves. BMW recommends intake valve cleaning in the form of walnut blasting roughly every 30,000 to 50,000 miles.
What noise does a wastegate make?
External Wastegates are responsible for turbo flutter. That fluttering sound, which typically occurs when the throttle is suddenly closed, is the sound of the turbo trying to push air into the engine but failing, so the compressor blades ‘chop’ through the air. You can read more about this phenomenon here.
What’s a bad turbo sound like?
Loud noises: If your vehicle has a bad turbo, you may hear loud noises that sound like whining or screeching. So if your vehicle is running and you hear a loud whining sound that increases in volume as the problem goes unfixed, this is most likely to do a turbo problem.
How do you test if wastegate is working?
- Clamp the actuating line to the wastegate using a hose clamp.
- Test drive the vehicle and determine the available boost pressure. CAUTION!
- If the boost pressure achieved is 1.75 bar as indicated on the car’s boost gauge, the mechanical portion of the charging system is working properly.
How do you test a wastegate on a turbo?
Do you need a tune for wastegate?
*Please note that our actuator requires a custom tune. This cannot be used with any off the shelf tunes or with any other completed tunes from another tuner. You MUST request a custom tune from your tuner if you plan on purchasing and installing this wastegate.
What does tightening a wastegate do?
How do I know if my turbo has a boost leak?
Listen for any hissing noise—this will indicate a boost leak. If the air pressure gauge indicates no buildup of pressure or does not hold for less than a second, that’s a sure sign that a major leak exists within the engine.
Can you drive with a faulty turbo actuator?
Yes, you’ll still be able to drive your car if your turbocharger fails; however, engine failure won’t be far behind, so only drive on if you have to. As soon as you spot any of the turbo failure symptoms outlined above, you should get your turbo checked as soon as possible by a qualified technician.
What causes turbo flutter noise?
Essentially, the noise is caused by what is known as “reversion”. When a turbocharged vehicle builds up boost, and the driver backs off the throttle, the throttle body snaps shut, but the turbo is still spinning, trying to compress air.
What happens when the wastegate actuator fails?
This can cause serious engine damage, as the turbo will no longer have any boost control. This means the pressure will keep building, and the turbine will keep spinning until something breaks, or the engine management takes over! In most cases, the best solution is to replace the worn actuator with a new one.
