Repair of Damaged Audio/COMAND Wiring Harnesses
If audio/COMAND theft results in cable damage the wiring harness can be repaired or ordered separately.
An order and replacement of a complete interior wiring harness for the "frame-floor system" is not required.
Repair of "Non"-Antenna Lines and "Normal Copper" Lines
All "non" antenna or video lines and optical fibers ("normal copper" lines) can be repaired in line with WIS repair methods: AR00.19-P-0001A
Repair wiring harness as per specified repair method (Models 124, 126, 129, 140, 163, 164, 166, 168, 169, 170, 171, 172, 197, 202, 203, 204, 207,
208, 209, 210, 211, 212, 215, 216, 218, 219, 220, 221, 230, 240, 245, 246, 251,461,463) and AR00.19-P-0100A General repair methods for wiring
harness (Models 124, 126, 129, 140, 163, 164, 166, 168, 169, 170, 171, 172, 197, 199, 202, 203, 204, 207, 208, 209, 210, 211, 212, 215, 216, 218,
219, 220, 221, 230, 240, 245, 246, 251, 461, 463).
Depending on the model series involved, the wiring harnesses may be represented in different design groups.
Antenna Lines
Generally all antenna lines can be ordered individually or as modules through EPC by checking:
^ Qualified entry through vehicle identification number (VIN)
^ Select design group:
- ...54/410
- ...54/545
- .../82/310 (ascending)
Low Voltage Differential Signal (LVDS) Lines:
All LVDS lines (video line from COMAND to central display) can be ordered individually.
Depending on the model series involved, the LVDS lines may be represented in different design groups.
The LVDS lines are located in the following design groups:
^ .../54/410... "Cockpit wiring harness"
^ .../54/545... "Frame>floor system"
^ .../82/310... (ascending)2010 Mercedes Benz Truck G 550 (463.236) V8-5.5L (273.963)

SUBJECT:
All Models with M272 and M273 Engines Cylinder Head Cover Leaks
Field inspections of suspected cylinder head cover oil leaks, have revealed that unnecessary resealing is being performed where the cylinder head
cover is not the root cause of the leak.
In cases of customer complaints of oil leakage, it is essential to determine the actual source. A proper remedy should be applied to avoid repeat
repairs and unnecessary workshop visits (refer to other publications on the subject). For your convenience, a video has been created which outlines
the proper procedure to help identify the source of engine oil leaks. The video is available as of the 11/2011 Star Diagnosis release and can be
accessed through the following path:
SDmedia--> Symptoms/Topics--> Engine--> AR - Localize oil leaks on major assemblies [Model Passenger cars]
The new generation of Mercedes-Benz engines have chemical sealers (sometimes referred to as "formed-in-place gaskets") applied to sealing
surfaces by robots during the engine assembly process. This engine sealing technique called the RTV (Room Temperature Vulcanizing) uses the
silicone rubber compound. This precise and uniform application of silicone at the factory insures proper adhesion and a leak tight connection that
very rarely leaks.
During necessary engine resealing repairs, care must be taken in preparing surfaces and applying silicone compound. Do not clean surfaces with any
abrasive materials or sharp tools. Only approved Loctite cleaning spray must be used when prepping engine surfaces (refer to published
documentation on the subject, such as bulletin S-B-01.10129(x)).2010 Mercedes Benz Truck G 550 (463.236) V8-5.5L (273.963)

Only 1 millimeter (+/- 0.2 mm) thick silicone bead should be applied uniformly to one side of sealing surfaces on a precise pattern (refer to Figure 1
and 2 and / or WIS doc AH01.30-P-1000-08V). A small amount of oil should be applied to camshaft bearings. Sealing surfaces must be assembled
within 10 minutes of sealant application.
