==Swapping Instrument Cluster==
Pre-[[facelift]] vehicles have no redundant mileage storage, thus the only place mileage is stored is the instrument cluster.


===Using the MFD Hidden Menu for analysing the battery voltage (UB)===
==Driving without instrument cluster==
#Access the MFD Hidden Menu as above.
It is possible to drive without instrument cluster, but the following side-effects will be observed:
#:When first opened the MFD will display something like "UB:12.3V".  In this example the 12.3V is the battery voltage with the car at rest with engine off and alternator not charging. The voltage should be between 11.8V and 12.5V and will typically be 12.3V with a new battery and the car at rest for about 24 hours or more.
* High beams cannot be switched on (they can, but require pulling the lever to yourself and keeping it pulled)
#:[[File:01 MFD Hidden Menu UB Engine Off.JPG|500px|center]]
* Turn signal lights will work, but the sound feedback will not be present
#Start the engine.
* Door control module contour lighting does not work
#:The MFD Hidden Menu will now display something like "UB:13.8V".  In this example the 13.8V is the battery voltage with the engine on and the alternator charging.  The voltage should be between 14.0V and 14.2V. and will typically be 14.0V with a new battery and after the engine running has been running for several minutes.)
* While engine running and key in ignition, it is not possible to open trunk with the button on trunk or the button in driver's doors
#:[[File:06 MFD Hidden Menu UB Engine On.JPG|500px|center]]
#Note the battery voltage displayed is very dependent on factors such as;
*How long the engine has been running and hence the alternator has been charging.
*The state of the battery charge.
*The age of the battery.
*What electrical load there is on the battery. For example having the headlights on and or the Air Conditioner on may reduce the actual battery voltage.
*The performance of the alternator.  A slipping Serpentine belt or a faulty alternator with say failed diodes or faulty voltage regulator circuit will affect the displayed battery voltage.

===Repair===
The W220 S-Class, has an interesting lighting architecture, incorporating LEDs and fluorescent tubes to generate illumination and back-lighting on the gauges.


==Issues==
Usually, the parts that have to be replaced are 1 transformer and 3 transistors:
* The fluorescent tubes used to generate illumination and back-lighting on the gauges eventually flicker and die.
* BOSCH (VOGT V7) transformer. 8948411098, 8 928 460 001, 73173 H
* Missing pixels due to ribbon connector failure.
* MOSFET BUZ102S transistors (2pcs)
* MOSFET BUZ102SL transistor


===Display Defective Warning===
In most cases, only the transformer is at fault. Hence, it should be replaced first, before replacing transistors.
[[File:W220_display_defective_visit_workshop_facelift.jpg|thumb|none|"DISPLAY DEFECTIVE VISIT WORKSHOP!" warning on the instrument cluster.]]


It is useful to purchase the original VOGT transformer (~48 EUR), as there have been reports that cheaper Chinese replacement transformers are sometimes going bad some time after replacement (see the photo above).

Repair service as of August of 2019 is cheap enough still not to bother taking it apart yourself in order to first diagnose which of the 3 mosfet transistors or
the high voltage transformer is the culprit,  ordering the replacement part, waiting, replacing and hoping it all works.
As of August, 2019, the repair service is still cheap enough (right around #200).

===Lighting Repair===
====LED upgrade====
The W220 S-Class, has an interesting lighting architecture, incorporating LEDs and fluorescent tubes to generate illumination and back-lighting on the gauges.
The tubes eventually flicker and die, causing this malfunction to be a recall notice with Mercedes.
Recognized for up to 10 years from MY, for registered owners, Mercedes will honor the recall, with enough coaxing.
For everyone else, repair is the only option.
Chinese made substitute transformers and FETs may do the trick, they may not.
With this set of instruments, repair was not an option, so an experimental LED substitution was attempted, and turned out successful.
An LED driver circuit replaced the 4000V transformer, retained the dimming ability, reduced current draw, and provided ample lighting.
White LEDs were grafted in place of the fluorescent tubes, and blue LEDs behind the LCD displays.


Video below shows how to test wiring of the instrument cluster connector and how to replace fluorescent tubes with LED strips.

Entering W220 instrument cluster hidden menu.

Access - MFD Hidden Menu

  1. Get into car and turn Ignition Lock to Position 1 (ACCESSORIES) but DO NOT start the engine.
  2. Set the Instrument Cluster Multi-Function Display (MFD) to show mileage (total vehicle mileage and trip miles).
  3. Push the R (reset) button on the Instrument Cluster three times within 2 seconds.
  4. The MFD will display something like "UB:12.3V".
  5. Use the Steering Wheel ‘UP’ or ‘DOWN’ buttons for other Hidden displays. The MFD Hidden Menu will scroll through;
UB (Battery Voltage)
DC W220MJ03 (Including ‘OIL LEVEL’ and Motor Type)
ESP DYNAMOMETER TEST
WIA TYP: (Including the VIN)
CONFIRMATION (Service Confirmation)

Setting Clock

With COMAND unit present, the time can be set in COMAND by pressing Service->System->Clock->Set Hours etc.

The time shown on instrument cluster can be set using steering wheel buttons only if COMAND has been disabled using DAS.

Adjusting time without COMAND available

Swapping Instrument Cluster

Pre-facelift vehicles have no redundant mileage storage, thus the only place mileage is stored is the instrument cluster.

Driving without instrument cluster

It is possible to drive without instrument cluster, but the following side-effects will be observed:

  • High beams cannot be switched on (they can, but require pulling the lever to yourself and keeping it pulled)
  • Turn signal lights will work, but the sound feedback will not be present
  • Door control module contour lighting does not work
  • While engine running and key in ignition, it is not possible to open trunk with the button on trunk or the button in driver's doors
