Displaying gallons remaining in instrument cluster.

Picked up a 2013 S550 Base on New Years Eve and wanted to get gallons remaining in the tank on the instrument cluster. The 2007 4Matic that I have has this enabled. Using Xentry/DAS this is what I did in case you want to do the same:

"Control Unit Groups" - "Information and communication" - "IC - Instrument cluster (Central CAN bus)" - "Diagnosis to plant specifications" - "Control unit adaptations" - "Control unit adaptations (Variant Coding)" - "Variantenkodierung" - "Tankinformation" set to "aktiv"

Follow this up with "Control Unit Groups" - "IC - Instrument cluster (Central CAN bus)" - "Actuations" - Control Unit Reset

turn off the mental red pump symbol too - otherwise it overwrites any info you want to see

Enabled gallons remaining in your 2013 S550 cluster using Xentry. Path: Instrument Cluster > Variant Coding > "Tankinformation" > set to "aktiv," then performed a control unit reset.

Can anyone post a screenshot of what that looks like? Like to see if it’s useful information displayed in a non-distracting place before I go ahead and do this.

Reiserechneranzeige bei 50% Reserve ohne Symbol

set to without (ohne) to remove the Overwriting of ANY info on the cluster with a retarded irremovable Red pump symbol - as its utterly pointless and bloody irritating when the gauge already has the yellow warning light on

Tankinformation aktiv

show another additional information menu in the cluster when you toggle the steering wheel up or down arrows - note - at your last gallon, the reading is wild as the last dregs slosh around
