First things first. Please click the user cp link and add your vehicle and location to your profile as that is often useful information.
Second, you've posted a rather technical issue into the general forum, but generally you'll get more useful information if you post in the forum that is specific to your chassis, which is the W210. Scroll down to the sedans forum and you'll see it.
Third, the first step I would take is to check for codes. Codes can set even if you don't have a CEL, and they can be very instructive when you're chasing symptoms. Once you get codes you can search them on the forum or post in the 210 forum and the folks there will probably get you squared away.
(I won't comment on the advisability of gunning it around a corner in the rain...)
Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy; its inherent virtue is the equal sharing of misery. (Winston Churchill)
