What year is the car? Tacho universal only can do CAS2 (white box untill +/-2005) but I don't trust this method (read manual), better is to make a backup first before zeroing the CAS. So buy a red clone CAS R260 programmer and you can do this job save. Most clusters need a new chip, I think you don't got a M35080v6 eraser.

mate pls check cas model no if cas3 tachoo not making
only read and write r260 or xprog mate

Hello I have model 2005year 9 months o( and dashboard has M35080V6 ( I change EEprom ) Can I zeroing with UPA? or red clone CAS R260 via OBD plug??

[vageric]

2005 models have cas 2.
R260 / upa can not make cas by obd2. you have to solder wires.
and tacho universal can make it trough tacho plug!

I tried it with TU. 1st I took a small fuse according to the instructions. Shut off the key. I've plugged into the connector. I put E61 CAS and showed that the old miles just ????????. I entered a new and confirmed km. TU show on and off lights. So I did, but at this point, nothing happens .....

Hello mate I think you have a CAS 3 unit as it changes roughly from 2005 cas 2 to cas 3 if im not wrong if dash has m305080vp chip then it should be a cas 3 which you can do via R260 programmer which involves small soldering points, but you must change the dash chip.

Remove the box ( 2 minutes) and look at the color of the CAS.

[Harrycz44]

where I find it pleas?

[vageric]

if you remove the box on your left (3 screw) then you can see the color of your cas. (white is cas 2 en black is cas 3).
then remove 1 bolt en 2 plugs en you have cas out.
watchout with flat cable, is very fragile!!!

Thank you I found it. It is CAS 2 white box. And why do not do it change with Tacho universal? Maybe I do it bad..

Can I do it with UPA? or must buy cas programmer

[vageric]

you must buy cas programmer.

[paradoxtr]

you can do it with upa. before read eeprom with upa then edit dump and write.
if you cannot edit km area, i can do it to you...
or you can do it with this software editing Digital Kaos (http://www.digital-kaos.co.uk/forums/attachments/f174/44744d1293740309-bmw-f01-new-7-series-cas-4-r270-1.16.rar)
