Complaint:
There are several types of complaint about poor wiping effect.
A: The wiper blades make noises (scraping/ squeaking)
B: The windshield is not wiped completely (streaking)
C: During the downward movement water is pulled back onto the windshield from the A-pillar (Figure 1)
D: After windshield cleaning, water keeps spraying onto the windshield for several wipe cycles (Figure 2)

Streaking due to excessive downforce of the wiper arm

Cause:
Re.A:
A 1: The windshield and wiper blades are contaminated with residues from car washing facilities, identifiable by the
water beading. The water does not bead on a clean, unwaxed windshield.

A2: The wiper blades are worn by mechanical damage (wiper lip damaged by ice or insect debris, or deformed by
long periods of disuse).
A3: Incorrect angle of incidence of the wiper arms to the windshield. Because of this, the rubber lip of the wiper blade
may not flip over at the reversal point.
Re. B:
B 1: Wax/ dirt residues on the windshield
B2: Wiper blades deformed or worn
B3: Downforce of wiper arm not OK (Figure 3)

Re. C:
Water is pulled back onto the windshield by the differential pressure created as the wiper arm moves downwards.
Re. D:
Washer water collects in the fastening of the wiper blade and is blown onto the windshield by the airstream over several wipe cycles.

Note and supporting information: Wiper blades are wear parts which, even when "not used" for long periods (kept in
park position), may become permanently deformed and damaged. Further stresses on the rubber wiper blade arise
due to various environmental influences which progressively change the effectiveness of the rubber wiper blade and
accelerate the aging process. Due to the natural aging process and wear, the wiper blades should be replaced twice a
year, preferably in Spring and Fall (see operato~s manual).
Remedy:
Re.A:
A1: Clean windshield with intensive cleaner A 000 986 40 71. Important: Do not clean the wiper blades otherwise the
graphite coating will be damaged.
A2: Replace wiper blades with genuine wiper blades
A3: Check angle of incidence of wiper arms. A correct angle of incidence of the wiper arms (position of the wiper blades relative to the windshield) is essential for ensuring that the wiper blades flip correctly.
Re. B:
B1: Clean windshield with intensive cleaner A 000 986 40 71. Important: Do not clean the wiper blades otherwise the
graphite coating will be damaged.
62: Replace wiper blades with genuine wiper blades.
63: Check the wiper arm for excessive resistance in the bearing. Restore mobility or replace wiper arm if necessary.
Re.C:
Problem inherent in design for which there is no technical remedy.
Exception: X204 up to 02/2014. In these vehicles it is possible to install the design configuration of vehicles as of
02/2014. This includes wiper arms (styled arms) with improved behavior in this respect. It is also necessary to replace
the wiper blades because the styled arms feature a Top Lock connection (previously Side Lock}. When installing the
passenger-side wiper arm, observe the new park position (21 mm) via the marking on the windshield (Figure 4).
Note: The modification cannot be entered in the vehicle data card. The customer must be advised that, when procuring replacement parts, wiper blades for the X204 as of 02/2014 must be ordered in future.
Re. D:
Problem inherent in design for which there is no technical remedy.
Note: - Check and adjustment tools case for windshield wiper systems, see Sl82.30-P-0004A - Wipe quality and noise
behavior, see Sl82.35-P-0002A- All about windshield wipers, see "AKU61S-direct" SDmedia under the heading "Electrical system - Windshield wipers" - W&G policies, see Sl82.30-P-0010A
