The "SOS nonfunctional" message appears sporadically in the instrument cluster of the vehicle. The fault code B129C00 is stored in the control unit log. The message occurs in particular after the vehicle has been non\-operational for an extended period of time; the message then disappears of its own accord after a few minutes. No functional limitation to the emergency call system is to be expected. Software error in N112/9 control unit for telematics services \(HERMES\). Software update for control unit N112/9 \- Control unit for telematics services \(HERMES\) to software release E522.8. If, against expectations, the erroneous display of the message in the instrument cluster continues to occur following the update, please create a TIPS case. - [LI54.30\-P\-070482](/bulletins/10177561.md), 2020-07-27, Service bulletin: EQUIPMENT; POWER TRAIN:AUTOMATIC TRANSMISSION; ENGINE; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL; ELECTRICAL SYSTEM:SOFTWARE. The check engine indicator light in the instrument cluster may be illuminated with one of the following fault codes: P261029, P02FF85, or P02FF02 stored in the engine control unit \(N3/10\). The time in instrument cluster is implausible due to an internal reset. If no other complaints exist then check for and perform any available software updates for the following control units: \- Motor electronics \(N3/10\) \- Powertrain control unit \(N127\) \- Instrument cluster \(A1\) If all three control units have the latest software installed and the complaint continues to occur then proceed with replacement of the instrument cluster \(A1\) Should the complaint re\-occur after the instrument cluster has been replaced then open a PTSS case with the following information: \- Control units logs for the ME, PTCU, and IC \- Initial quick test JSON: [/v1/bulletins/10252773](/v1/bulletins/10252773) [Report an error on this page](https://github.com/wenmar-pro/wenmar-open/issues/new?template=data_correction.yml&title=Data%20correction%3A%20Service%20bulletin%20LI00.20-P-077615&page=https%3A%2F%2Fopen.wenmarpro.com%2Fbulletins%2F10252773&vehicle=Service%20bulletin%20LI00.20-P-077615)
