according
the step 6. above and continue with step 8.

the engine must run
for at least five minutes before the load is increased.

and disconnect the hose to ensure that
no water can possibly enter exhaust pipes after washing.

and drain the water.

at higher output and,
as soon as possible, repeat the readings taken in step 1 above
for evalutation.

run the engine for 10 to 20 minutes after the turbocharger
has been cleaned. Doing so it is ensured that all the parts in
the exhaust system are completely dry.
