Sounds like a good theory to me! So good, I decided to forward it to the
group. Hope you didn't mind.

Yes, you are awfully close! It's actually the plastic housing of the
ignition switch that cracked and eventually blocked the steering wheel.
Good thing the engine gave up just before that...
I hereby confer upon you the title of Herr Stud von Typ 2. Congratulations!

PS: Any opinions on possible implications of sucking in fresh air instead
of inert gases through the EGR system?? Would I be running to lean, for
instance?
