My wife drove our 1999 C230 Kompressor through standing water in Arlington. We had it towed to a dealer and were told that water took out the MAS, air filter and got into the engine as there was water in the oil. What long term effects is this going to have, if any? They are fixing it and changing the oil, but I have concerns that the fuel system especially is going to get screwed up. How did the water get into the crankcase?
