bmw z3 cluster dump help

[chichomeyer]

Hi guys, I really need some help with a 1998 bmw z3, 1.9L, cluster.

It is the cluster with 3 connectors, a white, light blue, and a smaller black connector.

I was changing the kilometers and it looks like I saved my original files wrong.

The chip inside the cluster is a 93c46 and it also has the plug wich I believe is another 93c46.

I have tried downloading some of the dumps from other posts, loaded them, but with no luck. Maybe I fried the eeprom, but it still reads on my Tacho and with upa usb.

The clusters is HW:1.3 SW:7.0, in kilometers

Any help would be greatly appreciated

Thanks

What are you asking for exactly? A good dump?

You say you believe the coding plug is a 93c46? Did you not edit the mileage on the plug also?

Eeprom should be ok if it reads with programmer. What happens when you load a dump you downloaded?

Yes, l'm looking for a good dump. Yes, I also edited the coding plug with the desired mileage. When both dumps are loaded I get the Code-2 error on the cluster and nothing works. Thanks

Now that I loaded your dumps, I get Code-1 on the dash

I hope you loaded them x16bit.

Yes I did, desoldered the 93c46 from inside and loaded it in 16 bit using UPA USB programmer

[chichomeyer]

In case anyone wants the answer to this (9 years later), the files need endian swap to work (depending on your hardware programmer).
