Hi all, Came across this fault. It points to corrupted memory in VECU unit. Anybody had a problem like this? Or maybe knows more details about it? Maybe more detailed description and which parts inside VECU hold this corrupt memory? Thanks!

    OK it looks like I have a bad EEPROM chip or it's contens. Anybody by anz chance have a copy of this file?

    I don't know of any user serviceable chipsets in a VECU. I'd see if the VECU SN pops up on the display when scrolling through. If it doesn't, I'd start troubleshooting against ECU supply voltage.
