I removed one of the intercooler pipes to install an airfilter on our 2008 S240 and noticed some condensation/oil in the pipe and intercooler. Smelled like oil but was very thin. Seems the oily residue would trap heat in the intercooler. Is this normal? Just blow back from the intake pressure? Any reasonable way to clean and prevent this residue?

Cleaning it out is a tougher matter. You might remove the intercooler and run solvent through it.

Or do what I did, buy a new intercooler.
