    Ok, I'm fairly mechanically minded but the technology of these later models has me baffled. This A8L lights up, everything appears to come on but will not turn over, not a sound, no clicks, nothing.  Battery is fine, have tried the key in and out, checked out the fuses and all look good, ran the ODBII and got some O2 stuff but nothing that I think should prevent it from at least cranking.  I ran a CAN-bus (auto detect) old Ross-Tech VCDS (version 17.1) and other than the O2's there were no DTC codes that should prevent it turning over. And I cleared ALL codes too. I'm stumped...any advice?

    Hi!
    what is the battery output? If it is lower than 11.9 ? Volts, then it won’t even try.
    have you recently changed the battery? If so, did you tell the Energy Manager and give it the new battery codes?
