2013 W221 Drain pipe cleaning
There are a small draining pipe on both side of the car. They are connected to a car wide tray just under hood rear edge.
Now, in latest STAR magazine there was a story about used W221 available today and the writer emphasized the importance
of cleaning those ducts. According to him failing to do so may lead to electronic problems.
I tried to push a thin steel wire down the pipe, but it hit something and stopped at 1 ft deep.
Can not see there. Is there a tight curve of some kind or a barrier or is it so clogged?
Does anybody have experienced the same?
I would be be really thankful of good advise.

I think you mean the front windscreen drains - some of the most incompetent engineering known to man
go to a competent DIY shop get the 2 foot long pipe cleaner thing's (like these https://www.ebay.com/itm/156386116859?) open the bonnet - first remove the rain forest and new species growing there - then try and fight the brush in there with some water to wash the crap away
ENJOY - if you ever found the odd engine dip-stick that never fitted back in due to the stupid routing of the tube - you'll be right at home... FYI they exit on to the inner wheel arch liners
