"15" power signal being available to start the car. They unplugged the lights
and no more problem. It only took 2 months and numerous hours of trouble
shooting plus 3 techs working on it. The lights are mounted under the factory
front parking lights so with one guy working on it were hard to see, when
another guy was standing in front while one was working the ignition he saw
the lights doing weird things and found the problem.

So, no issues with any of the performance mods just a bad install of driving/
fog lights.

Get the car back this week and have to have the DME re-flashed as they
flashed it to stock for all the diagnostic work.
Wow....Glad you got it figured out! That is pretty F'd up though. I think I might be asking the person that installed those lighst to cough up all the diagnostic costs! (Unless it was you....in which case, you already paid )

Thanks for the update....May help others!

reviving an an old thread, but Iím having similar issues with a 997.1 tt. When you say you have ď15Ē power signal, were you reading low voltage on pin 15 of the obd connector? If so, what voltage were you reading?
