How to Clean the Turbo Without Removing It

Model: (Various brands) Various
Part: Turbocharger

Video tutorial

This video demonstrates how to clean the turbocharger on both diesel and petrol vehicles without removing anything: start the engine and let it warm up. Remove the air intake system, which consists of a flexible hose located between the air filter boxes and the turbocharger/intercooler.

For petrol engines, set it to about 2,000 RPM, while diesel engines can be left at idle without pressing the accelerator pedal.

When the engine is warm, spray directly into the turbocharger at short intervals to avoid an unexpected increase in engine speed. Continue cleaning until the product is fully used.

This product is readily available on all e-commerce sites for about £20. After cleaning, let the engine idle for another five minutes, then turn off the engine and reconnect the air intake hose, and drive for 5-10 miles within the limit of 3,000 RPM.
