Thanks for all of the info guys. I had it towed home today and it is in the garage. I will start digging into it tonight and see what I find. Fingers crossed!

Well I tore into it tonight and sure enough the start authorization module was wet. Not soaked or in standing water but it was damp. I took the case apart and this was a bit of corrosion on a few of the electrodes. I cleaned those off and will get some contact cleaner for it tomorrow. fingers crossed this will work. Could they have possibly put this in a more vulnerable spot? Geez, it is just begging to get wet.

..of the water ingress. It's probably clogged drains in the fresh air plenum or the sunroof. These are a long standing VW/AUDI issues across many models, (e.g. PASSATs).

Update: The car is alive again! It was water in the start authorization module. I removed the module and took it out of the housing, dried it off and sprayed it with electrical contact cleaner. Put it back in and it was good as new. Now I am just drying out the interior before I put the seat back in. I have since cleaned out the cowl drain and the AC drains. Hopefully I am good for a while now. Thanks for all of your help.

Congrats on finding the problems - Never think of the worst... A8L D3 just don't die over night. I should wait until Monday to ship the VCDS so you didn't have to waste the shipping money.

Cheers,

A can of contact cleaner beats the dealer every time.
