Topic: looking for a suitable tool to correct mileage in BMW from 2000 to 2010 (at least).


I’m often reading about Xprog, R260 and R270 but this confused me. . Don’t know much about short and effective the difference and pros/cons about these tools


Goal:to do CAS 2-3 and dash (incl. m35080 v6) in BMW from 2000 to 2010.



Good stickies for new users.

Xprog is universal programmer for varius chips in automotive and many more…

R270/260 is based most on BMW and MB immo systems+dashboards+some airbags..

it have function for erase 35080/35160 chips too…both are very good programmers and you need them both in this business..


R270 BDM programmer has the advantage to clear m35080 eeprom
R260 programmer is more safe in MCU
Xprog is a good tool for many chips and mcu
all are chinese
if you can pay more
, i suggest you to buy vvdi prog

Vvdi prog have the function of 260+r270


R270 does 080D0WQ very well – read , erase and write. But you need luck with a good quality tool .


If you are buying Rxxx tool..look for the new R280 CAS4 programmer. It have all functions of r270 and many more include cas4+ newest mask tipes..yust advice



Test result:

So yesterday I’ve had my first experience with R270.


Reading EE chips works for 90%.
But 30 attempts to write a blank 080D0WQ chip…failed
Then used a new 080D chip for the job….success

(Maybe the old installed chip was a bad ass)


In summary, R270 CAS4+ programmer on was possible to read, write and erase. 
The last- an important tip:

I think there are just a few % from the R270 on the market, which are useful. If someone is looking for it, try my link here: i have luck with it.
