Hi Guys. I have a R270 china clone that has the word "new CAS4" on the top sticker of the device which looks like this High quality R270 BMW CAS4 BDM Programmer (http://www.chinasinoy.com/wholesale/r270-bmw-cas4-bdm-programmer-629.html) . Recently I started having a problem where it would not read M35080. I get an error "no read eeprom". I thought it might be the socket so I resoldered it but that didn't help. I decided to wire up 8 28 gauge wires directly to the eeprom and the circuit board, testing each connection pin by pin. I get the same error when I try and read the eeprom. I am able to see the device in the device manager, I have updated the USB drivers as well. The little interface box makes the familiar click, click, click sound when I first launch the software and it appears it is communicating, just not reading the eeprom. I am using software version 1.16 and I also tried using version 1.14 with the same results. I downloaded version 1.20 but did not do an update to the device as I saw several posts about needing a code to do the update. I also saw this post http://www.digital-kaos.co.uk/forums/f173/good-soft-r270-v1-20-bmw-cas4-bdm-programmer-289512/ talking about an 800 ohm 1K resistor at R11 on the board. I am not understanding if I need to change this resistor or that post is for something else. Has anyone else has such an issue where it won't read the eeprom, and if so how did you fix it? I ordered several blank 080D0WQ eeproms from the UK to test with once I get them in case the existing eeprom is bad but I wanted to reach out here to see if anyone else has had this issue? Thank you so much DK members for your help.
