TO: ALL MERCEDES-BENZ CENTERS

SUBJECT

Models C-Class, CLK-Class, E-Class, and CLS-Class (203, 209, 211, and 219 platform) Model Years 2001-2011 

Mercedes-Benz AG ("MBAG"), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year ("MY") 01-11 C-Class (203 platform), CLK-Class (209 platform), E-Class (211 platform) and CLS-Class (219 platform) vehicles, the bonding between the glass panel and the sliding roof frame might not meet specifications. In this case, the adhesion of the bonding could deteriorate gradually over time. If the bonding adhesion were to deteriorate, the durability requirements might not be met which could lead to a separation of the glass panel from the vehicle. A displaced panel could increase the risk of a potential crash or injury for other road users. An authorized Mercedes-Benz dealer will check the glass panel bonding on the affected vehicles and replace the sliding roof, as necessary.

Prior to performing this Recall Campaign:

• VMI must always be checked before performing campaigns to verify that the campaign is required on a specific vehicle. Always check for any other open campaigns and perform accordingly.
• Please review the entire Recall Campaign bulletin and follow the repair procedure exactly as described.

Please note that Recall Campaigns do not expire  and may also be performed on a vehicle with a vehicle status indicator.

Approximately 681,843 vehicles are involved.

Order No. P-RC-2020040011

This bulletin has been created and maintained in accordance with MBUSA-SLP S423QH001, Document and Data Control, and MBUSA-SLP S424HH001, Control of Quality Records.

Revision Notes: 

• Information about TIPS case  creation added.

If it is not possible to perform the work as described in these instructions, the further repair procedure must be clarified via TIPS case,  specifying the codeword 19P7891003. 

CHECK/TEST PROCEDURE A

1. Move sliding sunroof to tilt position and check production date (Figure 1). 

   The production date must  be on or after 11-25-2005  or on or before 10-31-2007. 

   Vehicles with a registration date that does not  match with the production date of the sliding sunroof can also be affected.

   If the production date is nor  at the shown location (Figure 1),  this vehicle is nor  affected.

   If the sliding sunroof is not functional, loosen the two rear sliding sunroof panel screws (Figure 2, A), lift  the sliding sunroof by hand and then read off the production date.

1. Production date between 11-25-2005  and 10-31-2007: 

   Carry out Check/Test Procedure B. 

2. Production date not  between 11-25-2005  and 10-31-2007: End measure. 
3. No  production date present at shown location (Figure 1): End measure. 

The findings  from Check/Test Procedure B must be recorded in writing in the workorder. 

CHECK/TEST PROCEDURE B

suitable lifting tool (engine crane) and Special Tools (W 000 588 01 99 00) is required for the check. 

1. Perform function test for sliding sunroof.

   For this purpose, fully open and close sliding sunroof. The sliding sunroof must function correctly.

   This check serves as a comparison; it ensures that the customer cannot claim compensation for any preexisting noticeable problems (e.g. reversing, sluggishness, etc.) after the check performed with the cup suction tool. Point out to the customer that their sliding sunroof is not functioning correctly.

   Any repairs to the sliding sunroof identified above are the customers responsibility and are not covered by this campaign.

2. Clean the sliding roof panel and cup suction tool.

   The sliding sunroof must be closed.

   Special caution must be exercised during the check. The cup suction tool may be used for this check.

3. Position cup suction tool (Figure 3)  and pull as vertically  as possible (tolerance of ±10 degrees) using lifting tool (hoist/crane).

   The vehicle may need to be lifted to allow hoist/crane clearance underneath. The vehicle may be lifted with a floor jack at the front jack points enough to allow for this clearance and stay within ±10 degrees.

   Specified force 500 N/700 N (Figure 5). Please note that the scale is in N (newton) and should be measured in N. DO NOT attempt to convert to any other measurement. An incorrect conversion could result in an inaccurate test result and/or damage to the testing equipment and/or the vehicle. Any costs associated with an improper repair will be the responsibility of the repairing dealer. 

   Before the start of the measurement, the "(auto) hold function" of the hanging scale must  be deactivated and the measurement scale is set to N (see operator's manual). (See Figure 4)  for correct scale display.

   No  "hold function" may be activated so that the current pulling force is always displayed.

   Position cup suction tool at 5 positions in the sequence 1, 2, 3, 4, 5: (Figure 5). 

   The specified force must be monitored during the first minute  and adjusted if necessary (tolerance ±10 N). The specified force must not be exceeded.  Pull as vertically as possible (tolerance ±10 degrees) at the specified force. There must not be a person inside the vehicle during the check, and the vehicle must not be touched if possible.

   The holding time per position must be exactly 10 min. 

   Attention, danger:  Wear safety glasses and stay clear of the area above the cup suction tool (head/face) during the check.

   The sliding roof panel is lifted out of the roof frame noticeably at the rear test positions 1 and 5 (Figure 6). 

   If the sliding roof panel detaches from the padding of the tilting/sliding roof frame at one of the test positions (see Figure 7),  the sliding roof panel must be replaced.

   1. If the sliding roof panel detaches from the padding: Carry out work procedure. 
   2. If the sliding roof panel does not  detach from the padding: End measure. 

   The findings from the check/test procedure must be recorded in writing in the workorder. 

4. Perform function test for sliding sunroof.

   To do this, open and close the sliding sunroof (tilt and slide positions).

WORK PROCEDURE

1. Replace sliding sunroof.

   The accordion boot need  not be removed completely. It is sufficient to slide it back (Figure 8). 

   It is not necessary to prepare the strip of cardboard.
