W203 2005 cluster problem

[simppa80]

Hi!
Car is W203 facelift and I think someone have canged mileage by not so good results. Preglow light wont work, check engine light and that "EZS? red circle" wont work also.

I have read kilometres by Star and it says 117 000km like I see in dash. But dash is not "connected with EZS". EZS kilometres in Star are 999999 ?. Dash gives also ROM READ ERROR fault. In Dash assyst memory shows only 5 last service so it shows 58100, 58100, 58100, 78200, 101000. Can I find more Assyst services or somewhere else to know real kilometres?

I have opened dash and measured by meter those faulty lights leds and they are ok. Also checked by Star that preglow and check engine light are in use. Output test also done. Is there posibility to repair cluster and connect it with EZS? I have not seen can filter there.

cluster is a 93c86 or 24c16?
and EZS is a 1j35d/4j74y or 912/9s12

Thank you for answer.

I Have not even idea what chip is in there? It is diesel cluster. Do I need take cluster and EZS open to see that? What are differences?

From 2001 to 2002.5 cluster is a 93c86 + EZS 1j35d/ 4j74y

From 2002.5 to 2006 cluster is a 24c16 + EZS 912 / 9s12

I have 2005, so 24c16 + EZS 912 / 9s12.

Sorry, but what are these: dpf? eu4?

Hi, I think that someone first put large km on dash (example 999000) and put back dash in the car. EZS take new km from dash (999000). After that remove dash again but this time do km adjust + flash cluster. Now you dont have connection between dash and EZS and dash show new km.

Thank you Vladimir for answer. That is one thing what I want to hear. So there is now maximum km in EZS -> 999998? Could that sync connection problem + rom read error make my cluster warning lights defect? What I need to do for make dash and EZS sync again? Is that tricky job?

If I now buy new USED cluster will it shows it lasts kilometres or "------"?

Yes You can by used cluster and recode them by Star diagnostic tool. Of course you must first adjust km in EZS and in new cluster.

Dash can be programmed without copy km from ezs.
