Complaints about wiping effect of windshield wiper

Topic number Ll82.30-P-059239 Version 2 Design group 82.30 Windshield wipers Date 08-22-2014 Validity All passenger car model series Reason for change 1. Remedy added for issues due to water splashed back onto the window (C/E-Class) 2. Note that costs for the conversion of the wipers (X204) are not warrantable repairs Reason for block

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)

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

83: 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 se veral 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 operator's manual).

Remedy: Re. A:

A 1: Clean windshield with 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 bla des relative to the windshield) is essential for ensuring that the wiper blades flip correctly.

Re. 8:

81: Clean windshield with cleaner A 000 986 40 71. Important: Do not clean the wiper blades otherwise the graphite coating will be damaged.

82: Replace wiper blades with genuine wiper blades

83: Check the wiper arm for excessive resistance in the bearing. Restore mobility or replace wiper arm if necessary.

Re. C:

Due to the physical properties of water 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).

Notes: Costs for the conversion of the wipers (X204) are not warrantable repairs. 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:

Issue inherent in design for which there is no technical remedy.

Exception: Model series 204 C-Class and model series 207. On these vehicles the wiper blades of the model series 212 can be used to improve the situation.
