Due to this I loaded up IstaP, and was able to run a FULL scan and update. After some issues due to an aftermarket head unit (swapped the OEM back in and went fine) I managed to get all the way through the update procedure, the only error being the satellite tuner (which i dont think i have anyways).

Unhook my MST-80 voltage regulator , and car starts and runs beautifully. Many of my little annoyances are now gone !

Happy day......NOPE.

Go to start it this morning , no crank, no start, no anything but lights, HOWEVER, i have full access to ista+ istaP and inpa, and the only fault codes showing are from FRM (leds and such from previous mods.)

With no real error to go by im not sure where to start.

is it possible I fried my battery and am having low voltage issues? or maybe something more scary?
What are the specific codes are you seeing and how did you read them?

In any case, since you report that the car started and ran after your update, a low voltage condition developing overnight (i.e drained or damaged battery) is a reasonable suspicion. So start by measuring the voltage. You can do this most easily with a simple $5 DVM from harbor freight or easily enough with INPA.

FWIW PK73 and PK77 are the same car but the former is assembled in Germany and the latter in South Africa (https://www.google.com/url?sa=t&rct=...7rR6cqhET6sNy4). Realoem is not perfect - I've seen it make errors - so that could be the explanation.
