[Vwdiesel] Engine Carnage Shots

[James Hansen]

An alarm on the engine oil temperature should give reasonably similar
results. 
If both the coolant, and engine oil fall out, you're so very screwed anyway,
there is nothing left to save.
I've learned a lot about engine monitoring from racing stock cars.  There is
NO replacement for a giant red warning light, or in a reasonably quiet
environment a horn such as Sandy suggests.  I know many people that have
lost engines on the track, they have a sea of useless racerboy gauges in the
dash, but are too busy to look at them, can't see them, vibration, etc, and
really, while driving, you shouldn't be staring at gauges.  
A good gauge/switch combination would be one built by Murphy Switchgauge (if
they still exist) that gives you a visual gauge to reference on occasion,
with an adjustable contact that the gauge needle hits to set off an
alarm/light etc.
There are also screw in sensor switches that can activate stuff like lights
or buzzers.
On another note, I very much like engine oil monitoring to show you how
loaded/overloaded your system is, and gives a better indication than coolant
temperature in my mind.  I've melted plastic labels off filters on a motor
that ran warm, but not excessively hot coolant, but had other issues.

I Don't own any TDIs, just old 1.6s and one AAZ.
But look for a non-critical (no head bolts!) fastener, like a bracket bolt
or screw. Should be right against the head or block casting, might have to
be mounted on a small aluminum plate captured by said bolt. 
Valve cover screw might work, but damage might occur before the heat gets
there.

Also out of the draft so heat is not sucked away too quickly.

I had a similar coolant loss meltdown years ago with my Mercedes 200D, but
the stink woke me up in time, and she survived to run again without rebuild.
Alas, in a bus, the stink is behind you (sorry Dave).
A truly amazing engine! I did a manifold clean out once, it was coked up
about half restricted, the car lasted 20 years, retired due to body
disintegration. Drove it to it's final rusting place. The engine went on to
other things, not sure where, or how long it lasted.
