This is a recent one. I noticed the other day during a heavy rain storm that my passenger fog light was on. The car had been off and sitting for a few hours so I was thrown for a loop.
During today’s thunderstorm, it’s happened again. Any ideas?
Sure enough, this is what it is. I went out for a drive this evening and every possible warning light popped up and starting flashing on the instrument
cluster (EBV, ABS, ESP Inoperative. Cruise Control Inoperative, Parking Brake warning, seatbelt unbuckled etc.)
Took a can of compressed air and blew throughout the area behind the front SAM and out rushed a river of water down behind the front driver's
wheel. So far this seems to have solved the issue, although the check engine light is still on. Connected OBDII reader and gave me mostly drivetrain codes, with
one for the throttle position sensor, despite giving the car a few standstill revs and it happily obliging, not sure about that one. A new throttle pedal is still on my mind though, as
the "ESP Inoperative" is still getting in the way of my 40mph pulls.
Is this a common spot for leaves and debris to become clogged? Definitely recommend W204 owners to check this area out.
