Salut
Aucune idée je l'ai acheté sur ebay.
Sur la coque en plastique la date de fabrication est de 1995 donc logiquement le "firmware" devrait connaitre la M3.
Sur un forum américain j'ai trouvé un gars qui semble avoir fait des recherche a ce sujet :
I read a lot about this OBC problems regarding fault Check control and fault fuel Consumption.
I instaled a 18button OBC in my 320iC E36 1/97 because i found the 7button discusting with the
smole display and low functions. Regarding the problem I spoke with a lot of BMW fanatics (many
mecchanics in slovenia or germany/austria) and they all told me the same staff:
- All OBC are the same. If you chech the ETK code are all the same, they change only by language
of buttons (the can by changed from other units to units – mine is Italian beacuse the car is too).
If you buy a NEW one from the factory it comes uncoded (the same for ALL models, apart the language
of the buttons) and you have to code it (it is done by the RDX and TDX data line conected to all
digital modules of the car (EWS, DWA, OBC,…))
- The OBC check control works by getting data from the Check control module (above the left speaker above the foot)
and it is conected to the OBC by 5 wires. The are al digital (1 and 0) and it reads al the fault code
(lights front, lights back, water level, colant level…)
- If you change a OBC whitch is NOT from the exact car (year, macchine) you have to coded it
- the coding is done by the BMW repair shop (by us it cost about 20euro or 25$)
- If your check controlo reads error is because is not in sincronyse with the check module or the data
lines are not conected (my didn’t have CC but is working apart the CC reading – it displays the orange
squares on the holl display with the Check button
That is the part that the mecchanics told me, I am waiting to get an answer for my email. I the future
(on april with the opening of the sezone I will doo the coding + ne remote key and all module reset,
because I have a problem with the sincronyzation of the DWA and ZKE)
But I have a question: until I do the coding I vill must look to the 2x times to low fuel rate. The calibration allows
only from 0.75 to 1.25, so I am gessing that the problem is because the OBC is from a 318i 1993. Does any one have
the codes of EINHEIT1 and 2 for a 1997 convertible M52B20 (or it would be the best that al with the OBC functioning would check the code (2min of work) and write them down with the engine tipe (because of the vanos), and model year (it would be wery help full and
maybe we can solve the problem for all
En gros il dis que fondamentalement tous les ODB de e36 sont les même mais qu'ils doivent être codé pour chaque modèle.
Il faudrait à priori ajuster les EINHEIT1 et 2.
C'est les codes qu'on trouve dans le menu caché 11.
Moi actuellement j'ai 08 et FF.
Je vais fouiller de ce coté (si un proprio de M3 3L peut regarder ses codes ca serai sympa).
