Had the dealer replace the box and wire last month, cost me $500 and I had no fans so I could not drive to a local tuner.
So last week, when I finally drive it, if I turn the AC on.. all the check engine lights pop up, radio dies, and once I shut it down it's like the battery is dead. Let if rest for 30 minutes and it runs fine again, until I turn the AC back on.
I hate German car repair shops...
