CEL after windshield washing
Hi guys,
for 2 years i am having CEL on and local dealer just clear it. no obvious performance or consumption issue noticed. see my previous thread here
https://mbworld.org/forums/gl-class-...de-106c00.html
The other day, when CEL was off, i washed windshield only in order to apply nano cover and then poured some water, not much 2-3Liter. after 1hour i started the car and immediately CEL came ON. (it was not raining for several weeks) as you see my previous thread, i also noticed it turns on when i drive in rain. so i am confident now this is related to water. but i am unable to identify real cause of it so asking your help to guide me. Where should i check water tightness? engine area? or maybe exhaust area? Top of the engine or bottom? rear/front?
since washing windshield touches only front area, i assume engine area is best bet. could this be along the chasis, under the windshield? any sensor around there?
except removing engine cover, any other things that i could remove myself in order to make it easier to investigate?
Thanks in advance.
