Shit!! And youall say i should do this at home, by myself... Ufff noo w😂aaaaayy

[@MinitoolsChannel]

​@@vladito80 We do realize it’s one of the most difficult DIY repairs as it needs programming and soldering experience, but it’s not impossible! We know that using an EEPROM programmer may be difficult for somebody without programming experience; however, as we provide step by step instructions on how to use it for this specific instrument cluster, it’s not actually that hard! Soldering may be a bit tricky, but if you’re interested in getting a bit of knowledge about it you could look at this video th-cam.com/video/soDUnUyZYxE/w-d-xo.html

Perfect, thank you❤

Dear Sir!
Please help me.
The tachometer of our B-Class W245 car, made in 2005, is lying. Sometimes it shows more, sometimes less, but sometimes it stays at zero and does not move.
Where should I look for the reason why hpol is showing so much and so much? What could be the most likely reason. Possibly a soldering error? Or could a contact be faulty?
Thank you very much in advance for your kind help!
Best regards, János bohus

Just where will I find the calculator?

[@MinitoolsChannel]

Hi, you can find the calculator opening the PDF below the product description, at the following link store.minitools.com/en/sepdisp08-7v-mercedes-class-a-b-lcd-display.html

Why not use a resistor instead?

[@MinitoolsChannel]

Hi, because adjusting the voltage using a resistor is not as accurate as the method shown in the video.
