I was wondering if anyone had a similar problem, the doors in the bumper fail to close completely after the headlamp washers deploy on my 2014 c250 coupe, although they hardly ever get used I still find it ridiculous that I have to close them manually when I exit the car. They close about 75% of the way (both sides) and seem to catch on the bottom edge of the doors against the bumper. My car was only a few months old when someone backed into it in a parking lot breaking the lower and upper grill and dislodging one of the parking sensors, Mercedes carried out the repairs, removed and repainted the bumper replaced the grills and parking sensor, it doesn't appear that the paint thickness alone would be sufficient to be the cause of the problem is it possible that they could be misaligned somehow. I cant remember if the problem existed before the parking incident as I don't recall having used the washers up until then. Does anyone have any suggestions that don't involve entirely removing the bumper?
Thanks for any suggestions.
 
I would suggest that the repair was not carried out correctly , hence the 'sticking' of the washer nozzles.

When you say 'they don't get much use' what do you mean by that ? do you not drive in inclement weather/in the dark and use your windscreen washers much ? the two are linked via the cars 'brain' and unless manually operated (if your car has that option) they will work automatically at a pre set ratio according to windscreen wash use.
 
AFAIK the washer jets 'telescope', pushing the doors open when operated and return by spring pressure, closing the doors when the operation cycle has finished. On mine, with the lights on it takes 3 or 4 pushes of the windscreen washers to operate the headlamp wash.
Given that you say that you don't use the headlamp wash, I'm guessing that the telescopic action of the jets has degraded.

Yes maybe that's the problem, the only time I deploy them is if I remember to operate them prior to washing the car, I think it takes 10 operations of the screen washers before the headlamp washers cycle, perhaps they have become weak from age and not being used. The car gets little use and has covered only 49k kilometers in 9 years.
 
One of mine does that, I’ve poked about and it seems the little spring that pulls the flap back into the bumper has degraded. I’ll sort it when it gets warmer but it might be worth trying some silicone grease and cycling it a few times to see if that fixes your problem.
