Mine will start fine once twice 10 times a day then for some reason I crank it and its like the battery is only at about 10% with a jump it starts right up immediately and will start again no problem till the next time I never know when it will happen the voltage check when running is 14.2 the battery and cables are new I did notice early on if I lock the doors the battery would drain completely overnight Any Ideas?

I suggest you start a new thread. This is not the same issue.

Then I inspected the module in the trunk to see if there was corrosion from water leakage; nothing. Figured if the no start issue continued then I was down to ignition switch.

No longer a problem. Starter engages every time now. Must have been the clutch safety switch. Will report back if the issue comes back.

Thanks for all the suggestions.
Did you ever replace the switch, if so do you have the part number and how hard was it to change? I'm having the same issue with my 2000 A4.
