Question for the Abrites users about dme isn's
First of all I understand a lot of these tools can be hit or miss and I know people who have them put a lot of time in figuring out how to do things so I am not looking for a walk through more of an idea if it's possible, or has been done.
This R56 needs a dme. According to abrites as of the 32.6 version of the bmw online you are able to rewrite the isn through obd. Has anyone been able to pull this off. After pulling up the dme isn it allows me to change it and hit save but never says it has written.
My avdi is genuine but second hand it had a bunch of mercedes and VAG special functions but light on bmw all I have is bn012 (everything but cas programing and coding).
I have other means to modify the cas if need be buy its all on bench so I would rather avoid it if possible.
I also know the easiest way would be to clone it so I might suck it up and buy a liscense for one of my tools now or just send it off.
Again I am just wondering if it is possible or if anyone has done it.
Thank you everyone for your time
I have done ISN thru Obd2, You need to read the DME ISN then write it to the Cas unit. Usually requires a flash to complete. I would back up the Cas by reading it with a programmer not thru OBD2. Never done it with Abrites though.
I second warren thought I have done it throught obd but write into cas much safer on bench. Abrites is not ideal for isn either often problems with which dme is supported or not hex prog or explorer much better for isn. Which dme are you working with?
Thank you for the advice Taylor. That's probably what I'll end up doing. The cas Is under the upper dash pad so I was hoping to not have to touch that 15 year old bmw plastic lol. By the way its a med 17.2
Haha I completely understand I looked at a 03 mini the other day. They don’t age well. Let me know if have any questions along the way
It all depends on the DME hardware number. I have always had R56 units where the ME ISN could only be read. So you write the used ME ISN to the CAS and then Reflash used ME and re-encode it to the vehicle. You have to be careful of the transmission matching as some of the MEs do not like to cross over from M/T to A/T. I have an Abrites but not for BMW, I use other equipment for Beemer.
Same here, I have always been able to read ISN from DME, then write to CAS… here is a video from a 2009, process is real similar.. youtube.com/watch?v=r8z1Ph…
Tim, Cool video! What happens if the ISN is already encrypted? Does Abrites have the ability to de-encrypt it? Mike
