Thanks for the replies regarding the exploding glow plugs, all. I'm still
waiting to check the car myself.
I've been concerned about Bosch glow plugs (80006) for a while now, and once
heard a while ago that Bosch which made SPARK plugs for MB for a long time
was superceeded with NGK spark plugs, due to inferior quality drop after the
production of Bosch plugs was sent to Brazil. Could this be relevant to
Bosch glow plugs as well? I plan on trying the NGK plugs (2237) though
about 25% more cost.
Anyone use them or know anything about these rumours?
One of my suppliers says the Bosch application come with a big fat warranty
disclaimer now, something about overloading or something.
Bosch and Beru glow plugs have been and remain the standard by which
others are judged (and most of the other have been reported to be VERY
inferior). I have NEVER had a Bosch or Beru plug fail prematurely (in
less than 100kmi) unless there was some clear engine or electrical
problem that caused it. I can't say that about any other brand that I've
tried (Monark, AutoLite, noname). There is no stream of reports of Bosch
or Beru failures coming in from the guys that service MB diesels
routinely. The newer plugs subjected to "after start" glow may fail
sooner as plug failure is correlated with the duration and temperature
and the new systems are on longer, reach maximum temperature faster and
remain there MUCH longer so failures at 50-75kmi in OM606 engines
confined to a city commute are not unusual but NOT the result of
inferior plug construction or design.
