    ME7.5 HEX-V2 communication issues

    Hello,
    I have some problems with hex-v2 and ECU ME7.5 units. Today I tried read ECU on Audi A3 and it was impossible, other units(03,08,17,...) works OK. I tested it with VCP and comm with ECU works fine. On others cars with k-line ECU I have sometimes problem with comm. synchro and must tried twice or more for proper communication. With hex-can I didnīt have this issues

    Do you still have the older HEX-USB+CAN interface to use on the same PC and car type as a comparison? If so please try to run a complete Auto-Scan with each interface and post them here or send via email.

    Also, can you confirm that was a (8L) A3 which uses K-line (like a Mk4 based Golf)?

    Thanks for the screen shots. That VCDS VAG # is a mess and baud rate appears to be off. I think Eric will be in the office on Monday so I'll make sure he is aware of this.

    In the meanwhile, V2 and HEX-USB+CAN scans on a similar vehicle would be excellent if you have time next week.

    Best,
    Dana

    Hi Albert,

    Although your HEX-V2 was up to date, CB 4409 is our Release version. I bumped that interface up to the Beta channel meaning the next time you check for interface updates using VCIConfig it should locate this:

    CB to update from 4409 to 4411

    We would like you to try with the latest CB (4411) to make sure the results are consistent. Either way, the scans will be helpful when/if you have time.

    Best,
    Dana
