Re: battery twist switch accident
On a diesel engine (and probably the A4 too) nothing will happen if you disconnect power while the engine is running. The battery is only used at startup to turn over the engine.
Err not the case on quite a lot of modern diesel units which have a solenoid operated cut off device. Lose the power to that and it shuts down.
