Dann Dampfstrahler einschalten und los gehts. Du wirst Augen machen. MfG alexis

Klar macht man da Augen, denn BMW hat extra eine Anweisung gegeben, dass bei Schaeden durch Dampfstrahlen die Gewaehrleistung erlischt!!!

Should you steam clean your engine? BMW says don’t do it!

BMW first issued a warning against high-pressure engine steam cleaning on its vehicles in 1989.

BMW says high-pressure steam cleaning can force solutions into the engine harness sheath and associated cables, causing unusual problems that would not have occurred otherwise. BMW engine harness multi-plugs and related sealing measures are not designed to be subjected to the discharge velocity and force of typical commercial steam cleaning units. Further, cleaning solutions with the high-pressure discharge can leave conductive and often corrosive residues deep within the harness and cables.

BMW says its engines are rarely so encrusted with automotive residues and dirt that normal, low-pressure degreasing methods fail to provide proper, efficient cleaning. High-pressure engine steam cleaning is unnecessary and should be restricted to extreme cleaning jobs, such as commercial trucks, off-road vehicles, etc.




Here is the engine washing procedure recommended by BMW:

•Bring the engine to operating temperature, and switch the engine Off.

•Cover or shield any component--such as the ignition distributor, multi-connectors, etc.--in the area to be cleaned with plastic sheeting.

•Apply engine degreaser or general engine cleaning solvent to the dirty area, allowing it to soak for at least five minutes.

•Spray warm water on the area to be cleaned, flushing the solvent and the contaminants.

•Do not aim the water spray directly at components. Do not use the water spray any longer than necessary. Do not wash the entire engine compartment when only one area requires degreasing, such as the front crankshaft radial seal, M20 oil filter replacement, etc.

•Blow the cleaned area dry immediately with moderate-pressure compressed air.

•Start the engine immediately and road test the vehicle to confirm satisfactory operation.

BMW says it will not honor warranty claims for components damaged by improper engine cleaning.
