# Service bulletin LI72.20\-P\-075746 A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned. - Type: Service bulletin - NHTSA id: 11029083 - Published by NHTSA: 2026\-02\-28 - Manufacturer's number: LI72.20\-P\-075746 - Manufacturer's date: 2026\-02\-25 - NHTSA component: STRUCTURE:BODY; ELECTRICAL SYSTEM ## NHTSA's summary Complaint Tailgate opens unintentionally. Cause Accidental or unnoticed activation of the button to open the tailgate on the vehicle key. E.g. when stored in trouser pocket, handbag etc. Remedy As of the 6th generation, the vehicle key can be recoded so that the tailgate no longer opens as a result of a long press on the button, but by double\-clicking on the button instead. This reduces the likelihood of the button being activated accidentally or unintentionally. The recoding can be carried out as follows: 1. Add SA Code O19 into VeDoc \(O for Oscar, not "zero"\) • an XSS ticket may be necessary to add the SA code 2. Perform SCN coding of EIS N73 control unit 3. Deactivate the vehicle key \(a successful deactivation is indicated by the LED lighting up 2x briefly and then 1x for a long period\). 4. Place the vehicle key in the storage compartment on the key symbol and turn on the ignition. All other vehicle keys must be outside of the vehicle when doing this\! Perform steps 3 and 4 successively for all vehicle keys. Notes: 6th, 7th and 8th generation keys can be deactivated as follows: Up to modification year 22/1 double\-click on the locking button As of modification year 22/1, by pressing and holding the locking button \+ double\-clicking on the release tab On model series 167, the storage compartment with the key symbol is located in the armrest. The SCN coding from the EZS is only transferred correctly to the vehicle key under the following conditions: Only one vehicle key is located in the vehicle, this key has been deactivated and it is positioned on the marking in the storage compartment for the data transfer. The costs for this adaptation are to be borne by the customer. ## The document - [NHTSA's copy of the document (PDF)](https://static.nhtsa.gov/odi/tsbs/2026/MC-11029083-0001.pdf) - [If that address does not open, try this one](https://static.nhtsa.gov/odi/tsbs/2026/MC-11029083-9999.pdf) The document is the manufacturer's.
