Hi, I have been searching these types of issues for awhile now and havent found a definitive answer yet. I recently bought a 2006 A8l with the 4,2l engine, it needs a repair to the front passenger shock and is not currently running but the price couldnt be beat as I could scrap it for what I paid. Anyways, the problem is it does not even crank at all. I am not sure if this is an electrical issue or a dead starter. The battery was bad so I went to audi and installed a new one last night and before you ask, no i have no coded it yet as i am waiting for the vagcom to come tomorrow. Even with the new battery I am getting the battery management warning and the mmi shows at around 10%. Is it possible that the mmi reading that low would prevent the car from cranking? and is that fix as simple as coding the new battery? I know the work involved in changing the starter so im hoping it is not the issue but i know it is possible. I have scanned the car and do get the "starter jammed or electrical issue" or whatever code and i also have seen something about the trunk antena or something when it comes to the immobilizer. Not too sure where that is or what to do with that. Is there anything else i should be checking before the starter or anyway to trouble shoot this myself?
