I got the wrong one. I think the old one said "low note", but the new one sounds exactly like the one that's under /behind the headlight somewhere. (I cannot believe I can't find the old one, garage is a mess). The new (wrong) one is Bosch MB#A 203 542 02 20, says low tone on it.
I'm not really surprised there are 4 horns listed for theis car on MBSuperstore. Fastlane has one (probably the RIGHT one)

TIA,
-Tom
