Turbo too loud - 2000 Volkswagen Beetle

Chines purchase agency for turbocharger and engine parts

If the engine air filter is good, and the exhaust is not restricted, then check the turbo bearings

change the loud turbo and see if you will encounter thats faults again.thankyou

could be the turbo but check all turbo hoses carefully for splits

Remember, what is heard as turbocharger noise may not be caused by a noisy turbocharger. Before replacing a turbocharger perform the following diagnosis.
A. If a loud whine or whistle is heard during acceleration and increases or decreases with rpm and load. This condition is most often the result of a loose clamp/hose at the turbocharger compressor outlet, charge air cooler inlet, outlet or at the intake manifold.

1. With the engine running at idle and the transmission in Park or Neutral with the parking brake set, feel for boost air escaping at each connection between the turbocharger compressor outlet and intake manifold. For limited access areas, spray soapy water on those connectors and look for bubbles.

2. Check the exhaust manifold and exhaust system for leaks.

I hope this helped.

Thank you,

check pipe connected to turbo it maybe split/also turbo unit itself may need replaycing/fan inside turbo maybe worn

Check the clamps aound the Inlet and Exhaust sides of the Turbo, and the Rubber Boots that connect the High pressure Air flow to the Charge Cooler Inlet and Outlet sides and the Boot into the Manifold. Any of these defects will create this sound. Especially look for a Split in the Connecting Boots, which will reduce Intake Air Pressure and Volume, which indicates a fault to the ECM, and susequent warning.

check all the pipes for cracks turbo sounds like its doing its job but may be a cracked/split intake Hope this helps

Ok we figured something out. The turbo model has a rear retractable spoiler that flips up when you go above 45 mph and down when you go below 10. The later models just have a fixed spoiler. Still looking into if it should make that loud 'ratchety' sound.

leaking turbo hose? losing turbo presure thus the loss in power and the sound you here being turbo presure being lost through the bad pipe
