E46 vin change in cluster

[maaxxyy]

Hi guys, i,m trying to change a vin/chassis number in a E46 instrument cluster software version 20. Unable to code via DIS or NCS Expert. Does anybody have some instructions or help regarding this?
I have willem programmer, tacho universal 2008, INPA, DIS, NCS Expert.
Any help would be great.
I,ve tried using pa soft 1.36 but cant get any comms with various kl interfaces.

Hi

First read dump in M35080, and post it here.
Also post original VIN in cluster and new VIN

[maaxxyy]

Thanks for your help, but i do not see a m35080 chip on the cluster??

[teerak2uk]

depends on year of vehicle as to if it will have M35080 chip or not can you post some pics

[vares]

The eeprom is located on same side of PCB where is axles for arrows. You must completely dismantle and remove the arrows.

[maaxxyy]

I,ll post some pics shortly, thanks.

Arrows (Needles)

what year is the car

[maaxxyy]

will this require a new chip to be soldered to the cluster? or can the existing chip be reprogrammed in place?

[teerak2uk]

depends on what is on it

need pics yr etc to help

[vares]

There is no difference for years,eeprom is located on same place.From the year depends only on the type of EEprom 93s66 or m35080.

[teerak2uk]

yes same place but more chance is m35080 the newer the vehicle if m35080 v3 then remove chip/rea dump/save dump/zero chip/write dump/change km/solder back to board but if any problems read/write with m35080 then replace chip with new blank and write saved dump then change km


make sure you have a good saved dump before erasing chip


if 93s66 read/save/wrie new km any problems remove chip and try again

[maaxxyy]

The car is a 2001 330d.

[teerak2uk]

The car is a 2001 330d.

what tool are you using on it?

[teerak2uk]

Pls check pictures, pdf

[maaxxyy]

i,ve just checked, its a m35080 v3, i have tacho universal 2008, willem programmer pcb45, and blank m35080 chips. which is pin 1 on these chips? it has a tapered edge.

note i had a v3 that was a nightmare prob locked like v6

best procedure i found

diga menu
BMW
3er
E46
m35080
read and save dump

then remove and do the same and save dump

you now have 2 x saved dumps to work with

then in diga menu zero chip

m35080>0 and wait will take a little while

then write one of the saved dumps back to it and write the new mileage the solder back to it and test prob best to remove battery before carrying out any of this if you have any problems with it write a dump to a new chip


MAKE SURE YOU HAVE A GOOD SAVED DUMP


good luck




note position of chip before removal so not to resolder upside down by accident

[maaxxyy]

i still need to which is pin 1 tho?

[teerak2uk]

Pin 1 in picture indicated by red line

[maaxxyy]

my soic clip just decided to break, any other way????

[teerak2uk]

solder wire direct to pins

pin 1 indicated here by a dot or from the wedge side from the chip also see diagram for pin numbers

[dashradio]

Your missing the point of this post he is asking how to edit the vin number not how to do the mileage, you can edit the vin number without changing the chip as the vin is stored in the non protected area of the 35080 chip.

[maaxxyy]

i need to read the eprom with a willem programmer so i can open the file, has anybody done this with a willem?

[teerak2uk]

sorry i dont have Willem but plenty here use it

[dashradio]

If you can view your dump on a computer screen you need to edit in the Asctii column, read the link that i put above, it does not matter what programmer you use.

[maaxxyy]

i,ve read the eprom with diga, i cant put the file onto a pc???

[maaxxyy]

[maaxxyy]

Thanks for your help anyway, cheers.

[maaxxyy]

Finally got the vin changed, with a little help from PremierD, top bloke.

[teerak2uk]

:wink:


Thought he would be able to help as he has me

[maaxxyy]

Yes he is a top bloke, between his knowledge and a few hours of playing around with a bin file, i finally changed the vin and mileage. Secondhand cluster installed and coded. Thanks to everyone who helped me!!

excellent work what product did you use to code it with

[maaxxyy]

i used tacho universal 2008, bmw inpa, ncs expert and a hex editor. still having a few issues with the car, can faults but the cluster is coded, not tamper dot and correct mileage.
