I think his car is Tiptronic.

My guess is that Woody is correct about the ignition switch. Otherwise:

Tiptronic Selector switch (gear selector switch) on the transmission could be corroded or faulty. The car needs to be in (P) or (N) to crank the starter. I'm pretty sure that selector switch is what sends the signal.



After that, what about the Start Lock Relay? I think that takes the signal from either the clutch switch or selector switch and trips to activate the starter. In the trunk, left side.



Guessing is fun when it's someone else's car.
