Hello very good to all and receive a cordial greeting. I have a problem with the clock in my car. Every time I ride the clock it starts to turn until it reaches the exact time of the day. This has been going on for two days. say that I have done the update of the clock a long time ago and everything is perfect. It has been doing this for two days every time I start the car. I can change the time and date without problem and between winter and summer too. in xentriy / das there is no error code nor does the car have a single error. Any idea why this is happening. It is to say that I have taken the car very little in these months, maybe 1 day per week for a short stretch. It will be that the battery is a little weak. any help or advice is welcome and appreciated. Greetings to all from Spain.

 

when you say "I can change the time and date without problem" - that in itself is a problem - its NOT possible if the GPS automated time is on - which is the NORMAL condition for all GPS equipped W221s (and I didn't believe its possible to disable - unlike many other lesser mercs models of this vintage, that have cluster menus to toggle between auto and manual time and date settings).

Are you 100% sure you can really change the time and date ? or is it the normal I can APPEAR to adjust the time and date - but as soon as you exit the menus, and then go back in, the time and date is really what it was before you touched it ?

If you are indeed really able to adjust and get it to keep a different setting - I wonder if your GPS antenna has died - can you check the GPS and see if that's working correctly - if it doesn't even notice where you are that's a big clue the antenna is dead

thank you sir botus as always you helping us all in this great family. thank you. Now answering your questions. 100% sure that my gps is working perfectly is the first thing I check. The other thing, my car is from 2005, the first units, and the latest updates were made in 2008. I can change the time perfectly and I have the option in the menu to change between standard time and winter time, but if I click on the standard menu, it gives me the option Option to automatically switch between winter and summer. The strange thing is that it has been paddling for two days. In xentry / das the only thing that comes out is a telematic update that I have always had there. but since my command works very well I have not updated. besides that I already have the video option. It is very strange that this happens to me now in xentry/ You give no error. I will do tests. First take a long trip and give a good slow charge to the consumer battery that is in the trunk in case it is weak for some reason. I can't think of anything else at the moment. Another option would be to put the clock update cd again in case that can solve it. the latter is the last option. The other thing is to do a restart from the same command unit. or a reset from xentry/Das. Well once again thank you very much as always for your help








QUOTE=BOTUS;8833099]cuando dice "Puedo cambiar la hora y la fecha sin problema" - eso en sí mismo es un problema - NO es posible si la hora automática del GPS está activada - que es la condición NORMAL para todos los W221 equipados con GPS (y no creía que fuera posible deshabilitarlo, a diferencia de muchos otros modelos de mercenarios menores de esta época, que tienen menús de grupo para alternar entre la configuración de fecha y hora automática y manual).

¿Estás 100% seguro de que realmente puedes cambiar la hora y la fecha? ¿O es normal que APAREZCA para ajustar la hora y la fecha, pero tan pronto como sale de los menús y luego vuelve a entrar, la hora y la fecha son realmente las que eran antes de tocarlas?

Si realmente puede ajustar y hacer que mantenga una configuración diferente, me pregunto si su antena GPS ha muerto, ¿puede verificar el GPS y ver si funciona correctamente? Si ni siquiera se da cuenta de dónde está, eso es un Gran pista de que la antena está muerta

you can always get to menu choices too view and "pretend" to edit the time and date and the next menu is the choice to use or not daylight saving (by ticking a check box). But it has zero ability to physically remember any changes made to the time and date when the system is really using GPS derived time signals - you only get to tick daylight saving or not - as a real adjustment step (when the GPS signal are there)

are you saying if you go in set it to year 2025 and turn the car off - then turn on and it still says 2025 ? if so that's NOT normal - the analogue clock doing odd stuff compared to the digital clock is usually a sign the GPS info is muddled (or you are hiding the car away from the GPS signals - then it might do random things .... is the car outside ?)

 

....in a garage with no satellite signals and not having used the car for a long time - may well get the car muddled - the satellites used for GPS are not geo-stationary they wander and the car finds ones available on the day, 30 minutes later those ones are no good and it continuously finds new ones - as the year rolls by things can become a lot different - a 30 min drive with a destination set might well help it focus on using whats out there...

the other point I'm not sure if you are saying - did your car get the big 2008 update (at some point) and was thus running 422 (before the clock patch alters that Eng. menu to show 423) ?

 

I will look in this engineering menu or hidden menu and I will look at that data from the photo. I'll try a few things to find out where the problem comes from. If I solve it, I will put here the solution that worked for me. and how i did it Just in case someone else has the same thing. cordial greetings to all from mijas costa malaga. Spain. thank you

 

Hello, here I upload the information that I took out of the car yesterday when I got home from work. Here it was 03.24 in the morning. see if you see something strange or different that could cause this problem. thanks again everyone greetings












QUOTE=BOTUS;8833115]... en un garaje sin señales de satélite y sin haber utilizado el coche durante mucho tiempo - bien puede confundir el coche - los satélites utilizados para el GPS no son geoestacionarios vagan y el el automóvil encuentra los que están disponibles ese día, 30 minutos más tarde, esos no sirven y encuentra continuamente otros nuevos; a medida que pasa el año, las cosas pueden volverse muy diferentes; un viaje de 30 minutos con un destino establecido podría ayudarlo a concentrarse en usar ¿Qué hay por ahí?

El otro punto no estoy seguro si está diciendo: ¿su automóvil recibió la gran actualización de 2008 (en algún momento) y, por lo tanto, estaba ejecutando 422 (antes de que el parche del reloj altere ese menú de Ing. para mostrar 423 ) ?

so from the bottom of this photo , question marks seem to show up - its normal at certain times of the year - when in daylight saving mode from the very limited checking I have done post clock fix update

then as satellites base their time on GMT but call it UTC, you are two hours off GMT (which its supposed to be as Madrid in the summer = GMT +02:00) thus for the time you said you took the picture, it looks like the Car is seeing the correct time and date

is the analogue clock still being odd ? if so for me, next I'd park outside switch off the engine and remove the key - go in the boot and to the right of the spare wheel you should find a black flat earth cable bolted to the side of the boot with a red painted 13mm headed bolt - remove this for 20 mins and then reconnect (will need to reset windows and sunroof - at any point later to re-enable the anti-trap features). Start the car and see if the clock and the car find their way on the time - and remember how to work correctly going forward

 

I will try that and do it as you have explained it to me. see if it solves it. The truth is that what the clock does is very strange. no errors in the car and no errors in xentry/Das. I'll keep you informed. thank you. receiv

como los satélites basan su hora en GMT pero llámalo UTC, estás a dos horas de GMT (que se supone que es como Madrid en el verano = GMT +02:00) por lo tanto, para el momento en que dijiste que tomaste la foto, parece que el El coche está viendo la hora y la fecha correctas

¿El reloj ****ógico sigue siendo extraño? si es así para mí, luego estacionaría afuera, apagaría el motor y quitaría la llave; vaya al maletero y, a la derecha de la rueda de repuesto, debería encontrar un cable de tierra plano negro atornillado al costado del maletero con un rojo Perno con cabeza de 13 mm pintado: retírelo durante 20 minutos y luego vuelva a conectarlo (tendrá que restablecer las ventanas y el techo corredizo, en cualquier momento posterior para volver a habilitar las funciones antiatrapamiento). Arranque el automóvil y vea si el reloj y el automóvil encuentran su camino en el tiempo, y recuerde cómo trabajar correctamente en el futuro

hello mr botus Fixed the issue with the steps he gave me in his last reply. I also gave both batteries a good trickle charge. for the moment everything is perfect. I know my car is already very old and over the years it will do strange things but for now it is perfect. thanks my friend. receives a warm greeting.
