a160 dash compatability

[hooter]

hi experts, im new to this site and hoping someone can give me some help.
i have a mercedes a160 semi auto and the lcd display only partially displays so i decided maybe i could clean up the contacts but only made things worse, now i need a replacement dash.. i visited a local scrapyard but all the dashes they had had many more bulb holders than mine, the plugs were the same but i was unable to take it away and try it. my car is year 2000 if this helps. are all a160 semi auto dashboards compatable and would it need reprogramming? cheers

just took instrument dash apart and it looks like my dash has leds instead of bulbs for many of the displays where as the scrapyard had dashes with all bulbs and no leds.could there have been a facelift or a year change were the instrument dash was changed..??
