1). Enter repair order number. Garage/Dealer Information. (Not used for stand-alone SDS)


  1. Entry for Retrofit / Modifications

1). Brings up a display in German. No submenus. (Not sure of purpose or usage)



1) Start your car, hit the raise button, wait 2 min, hit the raise (lower) button again to settle your car.

2) When you go into your Initial Setup Screen, have your computer outside your car with wires running

through your open window. You probably don’t have a Romess meter, but you can quickly measure the

front wheels and rear wheels to make sure they are at matching height or close as possible while pressing

(+/-) raising/lowering your car by each wheel. I measured from ground to fender. It really doesn’t matter

if your lowest or highest at this point, just make sure your fronts and your rears are close as possible from

left to right.

3) Then press F2 when you within the listed specs and enter your Angles: i.e. 3.2 Front and -1.2 Rear

worked great on my CLS55. This set my height at 26.25″ front and 26.5″ rear.

4) Exit out of the DAS, disconnect cables.

5) Turn off your ign switch and remove key. Then turn your car back on, and follow Step 1. Your settings will

take place as long as your car’s initial angles were in spec.

6) Get to the 211 Section

7) You will get to the main menu

8) Then go to Func perf by more than…

11)Then Suspension

12)And here is where people have problems, they just go to actuations and then lower it, IT WILL NOT STAY

LOWERED this way, you have to go to “initial startup”.

Xentry User Manual 07


13)Then Initial with manual settings.

Xentry User Manual 08


14)Then F2

Xentry User Manual 09

15)Here you will see a screen that shows the voltages which correspond to the height of the vehicle. They

must be within the given ranges in the left hand column. Use the + and – buttons to lower the car.

(In my screenshot I am in the car with a friend in the back seat, so that is why it is at 3.27, it should not

exceed 3), then hit F2

Xentry User Manual 10


16)Enter in these inclination angles and if the car is within the voltages supplied in the page before, the car

will accept the new lowered setting, if not it will reject it.

Entry Beep Disable:

1) Now, how to activate the unlock and lock beep (honestly, one of the best mods to do if you have an older

model e55)

First Control units:

6) At this screen you will see a pull down menu with a list of different regions on it. The only ones you need

to worry about are USA with buzzer and Netherlands. If you choose USA, i will give you three short quick

beeps when you lock the car and one short when you unlock it. Netherlands will give you three longer beeps

when you lock the car and one long when you unlock it. Personal preference on which one you like. Then hit

7) Then F3 (YES)

Xentry User Manual 26


KeyLess Go Key reminder off

Go into the CGW and change KG to “Not Fitted”. It will still work. You will not get the annoying reminder beeps.

The Instrument Cluster will not turn red if you are at a stop, while in gear, and press the KG button like it does

now (telling you to put the car in Park). If your car is a wagon, the hatch will not open. That’s the only ill effects.

I know it seems petty but got to be very annoying.


Misc. Settings :

TeleAid Delete : Control units > ICM > Codings and adaptations > Special Equipment > TELE AID (set to “NOT PRESENT” and download to instrument cluster).


To enable cornering lights :


Set Turning Lamps to PRESENT


To enable tank content remaining (gallons left) :

Inf & Comm -> Instr. Custer -> Diag. to Plant Spec. -> Control Unit Adapt. -> Variant Coding -> Read Coding


and change….



– You then need to reset the “kombiinstrument” (reboot)

Reset in DEV: Steuergeraet Resetten (PowerON-Modus) (FN_Reset_SG_Power_ON)

Some reading led me to find some sites say to also enable: Menu RR: Reichweite/Tankinfo

But mine works without so I didn’t enable this second one…

To enable flashing brake lights on emergency braking (missing on my SAM)

Control Units -> Body -> Rear SAM -> Dev. Data -> Control Unit Adapt. -> Control Unit Adapt. (Variant Coding)

Scroll to: Parameter Notbremsung, in the submenu you will have two more options: select zugelassen (enable)

Think the first choice is flashing brake and second is hazard lights, enable one or the other or both…


Enable Date in the Cluster (I’ve yet to do this one)

Control Units -> Inf. & Comms. -> IC – Instr. cluster -> Diag. to plant spec -> Control unit adapt. -> Control unit

adapt. ( Variant coding ) -> Variantkodierung Werkseinstellungen: Set “Datumsanzeige Grundbildebene” to aktiv.


– Then reboot the cluster


Change Speed limiter:

Log on to DAS, connect to the car, select:

Control Units -> Drive -> ME-SFI 28 -> Development Data.

Then select the Control Unit Adaptations -> Explizite Kodierung


R230 Disable TPC Tire pressure monitor STAR:

So if you ever took your car to the shop to disable that annoying tire pressure monitor light on the dash and they

told you they couldn’t show them the steps.
