Problems with the on-board power supply voltage may also occur.
2010 Mercedes Benz SL 550 (230.471) V8-5.5L (273.965)   Page 59
Cause:
The condensation hose (right/left) on the A/C housing may either be dislocated, pinched/crushed (water collects in A/C housing) or leaking, resulting
in water entering the interior.
Remedy:
If the condensation hose (right/left) is dislocated, push it all the way back onto the outlet fitting of the A/C housing and check for tight seating by
pulling gently. If necessary, use a cable tie to additionally fix the condensation hose in place. Never use soapy water or silicone spray to install.
If the condensation hose (right/left) is pinched/crushed, it can be checked for free passage as follows:
1. Use the operating unit to set maximum cooling on both sides.
2. On the vehicle underside, check whether water emerges from the condensation water drains. If no water emerges, the hose is blocked. In this
case, reposition the hose correctly to ensure free passage or replace the hose if it is damaged.
Invoice the damage with reference to the appropriate damage code..

Order No.: S-B-83.00/135
Group: 83
SUBJECT: MY-All, Models All
Mercedes-Benz HVAC-Foam Cleaner - Work Procedure
NOTE:
This procedure is not approved for vehicles covered under warranty. Refer to LI83.00-P-051588 for details on which vehicles can be cleaned under
warranty using Mercedes-Benz Contra Sept disinfectant cleaner (S-B-83.30/134). Additionally, the combination filter is a maintenance item and is
not covered under warranty.
Procedure
1. Start the engine with the A/C ON, temperature set to coldest setting, inlet set for outside air (not recirculate) and blower set for high speed.
Note:
The A/C must be run for at least 15 minutes to get condensation to build on the evaporator. This will adequately wet evaporator and promote the
product's ability to clean.
2. Locate the evaporator core case and blower assembly by removing any covers below the instrument panel on the passenger's side that may cover
the case.
3. Remove the cabin air filter and close off the empty filter cavity with the filter block off plate
^ For models where the filter bock off plate is integrated with the filter media (as with model 204/212). Remove the filter media, leaving the
bare block off plate, which can be reinstalled for the cleaning procedure (Figure 1).
4. On vehicles with an activated charcoal filter, remove these filters as well.
5. Drill a 3/16" hole in an accessible location between the evaporator core case & blower assembly, depending on your vehicle model. Use a drill
stop set at the thickness of the case to prevent plunging into case too deep.
Warning!
Follow the diagrams for a given vehicle model series, otherwise damage to the evaporator may occur.
^ Only drill through the case skin and gently probe inside with a dull instrument for any obstructions that the nozzle may encounter. If needed, use
the supplied plug and find another spot to drill.
2010 Mercedes Benz SL 550 (230.471) V8-5.5L (273.965)   Page 47
6. Shake the disinfectant product can and with the hose attached to the can push the nozzle into position & rotate so the pointer faces the evaporator
core (Figure 2).
7. With the blower still on, start dispensing the foam in short bursts. As the case fills with foam, airflow will decrease from the vents. Pause for the
blower to push the foam through the core. (If the fan starts to squeak, stop dispensing while the blower catches up). As airflow resumes, continue
with short bursts of foam. If the system is overloaded by dispensing the foam too quickly, foam can escape from components under the dashboard.
NOTE:
Do not allow the foam to drip to any electronic components. Intercept any escaping foam with a towel.
To prevent possible staining, do not allow any foam to blow out of vents onto seating or other interior materials.
8. Continue with this application method until the can is empty then shut the system off completely.
9. After a minimum 10-minute wait, turn the blower on LOW to MEDIUM for 2 minutes to push excess foam out of the core.
10. Check that the drain is flowing freely under the vehicle. If there is no drainage, the drain is clogged. A clogged drain must be cleared.
Condensation will rinse out any remaining cleaner residue and contaminants.
11. Reinstall new cabin filters and activated charcoal (if equipped).
NOTE:
It is required that you replace the cabin filter after treatment. It is recommended that you replace the activated charcoal filters (if equipped).
Additional instructions for this procedure will be available via Learning & Performance:
VILT Course Code:X0001F-US.TTA (starting in second quarter 2012).

Reason for change Removed note to fax CAN log
Complaint:
Fault profile 1/2: The display of the COMAND unit (A40/3) or Audio 50 APS (A2/56) shows the message "Theft protection active".
Fault profile 3/4/5: Initial startup of the COMAND unit (A40/3) or Audio 50 APS (A2/56) cannot be performed with DAS/Xentry Diagnostics or is
aborted prematurely.
Cause:
Re. 1. The COMAND (A40/3) or Audio 50 APS (A2/56) is in the "as-delivered state". In DAS/Xentry Diagnostics go to Actual values/Theft
protection and check the status of the COMAND (A40/3) or Audio 50 APS (A2/56). Initial startup of the COMAND (A40/3) or Audio 50 APS
(A2/56) with DAS/Xentry Diagnostics was not performed during the last installation. The PIN is still stored in the COMAND (A40/3) or Audio 50
APS (A2/56). The COMAND (A40/3) or Audio 50 APS (A2/56) locks after approx. 50 activation sequences.
Re. 2. The COMAND (A40/3) or Audio 50 APS (A2/56) is in the "as-delivered state". Initial startup was performed approx. 2-4 weeks ago and the
PIN has already been redocumented in VeDoc. However, the initial startup was not completed properly due to a procedural error in DAS/Xentry
Diagnostics.
Re. 3. The COMAND (A40/3) or Audio 50 APS (A2/56) is in the "as-delivered state" and is new from the warehouse. Initial startup cannot be
performed with DAS/Xentry Diagnostics because the PIN cannot be read from the COMAND (A40/3) or Audio 50 APS (A2/56). During initial
startup, the PIN was erased with DAS/Xentry Diagnostics too early to allow initial startup to be completed successfully.
Re. 4. In model series 164 and 251 the EZS/EIS control unit (N73) A164 545 15 08 or A164 545 16 08 is installed. The EZS/EIS control unit (N73)
and the COMAND (A40/3) or Audio 50 APS (A2/56) are not compatible with the "Theft protection" function.
Re. 5. The COMAND (A40/3) or Audio 50 APS (A2/56) is in the "CAN signal disrupted" state. The fault code DA00 is stored in the fault memory
of the COMAND (A40/3) or Audio 50 APS (A2/56). Initial startup is not possible because there is a CAN fault. CAN communication to the
EZS/EIS control unit (N73) is disrupted or faulty.
Remedy:
Use at least DAS/Xentry Diagnostics version 11/09 with add-on 1352 or DAS/Xentry Diagnostics version 01/10 with add-on 1354!
Re. 1. Perform initial startup of the COMAND (A40/3) or Audio 50 APS (A2/56) with DAS/Xentry Diagnostics.
Re. 2. Perform another initial startup of the COMAND (A40/3) or Audio 50 APS (A2/56) with DAS/Xentry Diagnostics.
Re. 3. Report the case to your market coordinator with a control unit log of the telematics control unit. He will forward the case to Daimler AG
headquarters. They may be able to determine the PIN again. When the PIN has been determined, perform initial startup of the COMAND (A40/3) or
Audio 50 APS (A2/56) with DAS/Xentry Diagnostics.
2010 Mercedes Benz SL 550 (230.471) V8-5.5L (273.965)   Page 35
Re. 4. Replace the EIS (N73). To do this, determine the part number in the EPC system. Perform initial startup of the EIS (N73) and transfer the
chassis number to the EIS (N73). Be sure to use the correct upper and lower case letters. Perform another initial startup of the COMAND (A40/3) or
Audio 50 APS (A2/56) with DAS/Xentry Diagnostics.
Re. 5.a:
Check whether the chassis number has been transferred correctly in the EIS (N73).
1. Use DAS/Xentry Diagnostics to access the menu "EZS/EIS /Control unit adaptations / Write VIN" and check that the chassis number is
written correctly (including upper and lower case letters).
2. Perform a "MOST ring restart" in the COMAND (A40/3) or Audio 50 APS (A2/56) with DAS/Xentry Diagnostics. The menu item
"Restart optical ring" can be found in DAS/Xentry Diagnostics under Audio, Video, Navigation and Telematics.
3. Erase the stored fault in the Audio 50 APS (A2/56) and COMAND (A40/3).
4. Perform initial startup of the COMAND (A40/3) or Audio 50 APS (A2/56) with DAS/Xentry Diagnostics.
Re. 5.b
b: Check whether CAN communication is functioning correctly at the COMAND (A40/3) or Audio 50 APS (A2/56). Perform a quick test
to check other control units for CAN faults and process these faults completely. Then perform initial startup of the COMAND (A40/3)
or Audio 50 APS (A2/56) with DAS/Xentry Diagnostics.
Re. 5.c:
If there are no other CAN faults stored in other control units and the EZS/EIS control unit (N73) contains the correct chassis number,
but the fault code DA00 is still stored and current in the COMAND (A40/3) or Audio 50 APS (A2/56), please log the CAN-B as
described in the attachment. Create a PTSS case and attach the CAN-B log.
Note:
When an Audio 50 APS (A2/56) or COMAND APS (A40/3) with PIN theft protection is installed in a vehicle, the PIN code is
automatically redocumented in the VeDoc system (online) as of DAS version 11/09. After successful initial startup, please check whether
the PIN has been redocumented correctly in the VeDoc system.

For vehicles with VGS2 or VGS3
0717, 0718, 0722, 0723, 2767, 2768
Causa:
Rpm sensor fault
Remedio:
Process the speed sensor fault codes completely using the DAS/Xentry guided test (possible as of DVD 01/2011 and add-on 1740). This may or may
not entail a replacement of the EHS.
2010 Mercedes Benz SL 550 (230.471) V8-5.5L (273.965)   Page 20
In the case of hardware replacement (when SDS instructs to do so, see attachment) the adaptation data of the old transmission control unit is read out
in the DAS/Xentry guided test and transferred to the new control unit after the repair. Subsequently, the transmission control unit, which is bolted
onto the electrohydraulic controller unit (EHS), may only be replaced using the EHS repair kit (A000 270 17 00) In other cases SDS will provide
alternate instructions
See also the Akubis direct film: "Replacement of "fully integrated transmission control" (VGS) controller unit at electrohydraulic controller unit
(EHS) on automatic transmission 722.9"
The VGS Control Unit (Control Module) only is to be replaced for VGS2 and VGS3 Control Unit versions with these fault codes, when SDS
instructs to do so VGS Control Unit is available as EHS Repair Kit (A000 270 17 00) Complete valve body "Electrohydraulic Controller Unit
(EHS)" replacement is necessary for VCS1 Control Unit versions when SDS instructs to do so. Control Unit Version is identified from the
Transmission Control Unit Log.
Note in Cases where hardware replacement is specified:
This procedure differs from a complete valve body replacement as the adaptation data, coding and valve body calibration data are transferred from
the old VGS Control Unit to the new VGS control unit This data from the old VGS Control Unit is stored in the Star Diagnosis unit by processing
one of the above codes. The same Star Diagnosis SW stem unit MUST be used to process the fault code and perform initial startup of the new VGS
Control Unit. Failure to do so will result in the necessary data not being transferred and improper transmission functionality after VCS Control Unit
replacement.
1. Process the speed sensor fault code completely by following the instructions in DAS/Xentry related to the fault code Note: During the
replacement of the VGS Control Unit it is imperative that the position of the solenoid valves are noted and re-installed in their original positions
Failure to do so will cause a mismatch in the calibration data to respective solenoid valve(s) and subsequent shifting complaints.
2. Replace the VGS Control Unit per WIS instructions For the initial road test following VGS Control Unit replacement the vehicle must be driven
gently for the first several shifts in each gear since it will be necessary to bleed the air from the valve body. Until the air is bleed out irregular
shifting will be noticed momentarily and will clear up with subsequent shift processes. Because the adaptation data is transferred from the
original VGS Control Unit performing subsequent shift adaptations is not necessary.
Note:
It is not possible to repair the EHS (VGS) in AMG vehicles
