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.
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.
2010 Mercedes Benz E 550 Sedan (212.072) V8-5.5L (273.971)   Page 52
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

2010 Mercedes Benz E 550 Sedan (212.072) V8-5.5L (273.971)   Page 40
File/Designation
Cause
The steering boot heat shield with aluminum ring has loosened and is scraping on the steering shaft (Figure 1)
If the scraping of the aluminum ring on the steering shaft is not the cause of the scraping noises when steering, the problem is being caused by other
components. See other documents in Design Group 46.
Remedy
Replace steering boot heat shield with aluminum ring with a silicone heat
shield without aluminum ring:
Specify correct replacement part for vehicle through the EPC as indicated below in group 49.
Note:
The silicone heat shield is not a constituent part of the steering boot or of the steering boot repair kit. In the EPC this vehicle-specific component is
listed in Design Group 49 (Exhaust system) under 300 (Shields).
Removal:
- Separate lower steering shaft from steering column tube and steering coupling
- Remove steering shaft together with steering boot and heat shield towards the inside (see AR46.10-P-0621)
Installation:
- Fit new heat shield on lower steering shaft (Figure 2)
- Press silicone boot onto steering boot using assembly fluid if necessary. Observe correct alignment: The "TOP" marking on the silicone heat
shield must be positioned at 180° to the arrow marking on the steering boot
- Check that the steering boot is correctly seated on the lower steering shaft: The steering boot (black) must be uniformly visible across its diameter,
see arrow in Figure 3
- Fold over the bead of the steering boot; mount the lower steering shaft, with steering boot and silicone heat shield fitted, in the firewall and fold
back the bead of the steering boot, making sure that the arrow on the steering boot points downwards; in the engine compartment mount the
steering shaft on the steering coupling, making sure that the silicone heat shield is correctly seated
Example of silicone heat shield incorrectly fitted, see Figure 4
Example of silicone heat shield correctly fitted, see Figure 5

Validity All models
Reason for change New repair method
Complaint
Lamp unit fogged or droplets forming.
Cause
Due to the vent openings, the lamp unit is an "open system".
This means that acidic gases, moisture, dirt and exhaust gases can penetrate it.
This can result in deposits on the diffuser and lens.
Remedy
Check housing cover of lamp unit for natural fogging or dew as per LI82.10-P-050139.
1. If a reduction in the degree of fogging is visible, the pressure compensation membrane can be inserted after complete evaporation of the dew.
2. If no reduction in the degree of fogging is visible, the lamp unit is defective and must be replaced.
However, the cover with the pressure compensation membrane should also be attached in this case.
Note:
Residual fogging is possible due to the laws of physics and is OK.
Fogging does not impair the functionality or the service life of the lamp unit.
Pressure compensation membranes should always be used on both lamp units.
Attach housing cover with pressure compensation membrane:
1. Remove lamp unit
2. Remove all vent opening grommets.
3. Seal vent openings with sealing profile.
Important:
All openings must be sealed carefully for the pressure compensation membrane to work properly!
4. Insert housing cover with pressure compensation membrane.
5. Install lamp unit.
W/S 204 Attach pressure compensation membrane to housing cover of lamp unit:
1. Remove lamp unit
2. Remove all vent opening grommets.
3. Seal vent openings with sealing profile.
Important:
2010 Mercedes Benz E 550 Sedan (212.072) V8-5.5L (273.971)   Page 35

Validity Transmission 722.9 with engines 273, 272 and 642
Reason for change Model designations with engine 642 and engine 272 for which there is a remedy have been added under Validity
Complaint:
After a cold start, slight slippage may occur in the 2-3 shift when the vehicle moves off for the first time.
Cause:
A full basic charge for the K1 piston cannot be guaranteed with a cold start. This means that the plate contact pressure must still be built up, which
can lead to a single brief slip of the gearshift.
