[Vwdiesel] Burned out glow plugs

  My first thought was injectors BUT, ALL FOUR being bad at once?  Nope, 
Besides only two have pieces missing.  I'd be inclined to check the pattern 
or for drip on those two.
  With all four going I'd suspect first that you managed to put fast glows 
with a slow relay. I've seen them burned out that way.  The other thing 
would be either it's staying on too long (doesn't look like it) or your son's 

doing something to glow and re-glow and again.  Biggie to look for is 
the relay somehow kicking back on and staying on for some time.  All 
dead would be from all being on too long.
