Why do these gremlins always coincide with something else?
I will pull the dash and swith the seatbelt bulb over.

Ever since I had the fuse problem with the AC, which turned out to be the

Pre-glow must work since it starts normally in relative cold weather (<45F

hi all!
thanks for all the responses to my query!
pulled glow plugs to find out 2 didn't glow any longer. (all were
Bosch parts, and looked good otherwise.)
replaced with new set and all is well again.
seeing only 2 were dead made me think; this thing used to start well

There is a Mercedes-approved tool for this task. I think it is called a
pre-chamber reamer.
I used a wood dowel to probe around and knock off soot deposits. Seemed to
work fine and didn't look to be much different than the Mercedes-approved
tool. Just much less expensive.

hi!
no, the glow plug doesn't flash; never has.
i don't recall reading anything about flashing in the owners manual
(yes, i have one, and i actually read the dang things!); is this
something an '85 617 should do?
cheers!

thanks for all the input, guys. looks like i'll be doing glow plugs soon.
i vaguely recall hearing something about needing to ream out the
area around the Glow Plugs when changing them out; is that correct?
if so, does this require some special tool, or is there something
else i could use
When I got my 240D and the glowplug light wouldn't light I dinked around with
troubleshooting a little when I needed to just dig in and replace the plugs...

I'll second this. If the plug is bad, the meter will peg out and not drop.

My favorite way to test them is with an old-fashioned automotive

Come on guys! Do it the easy way! pull the plug to the glowplugs

Replace the set, if one is dead, more are going bad from the same thing.
Does the glow plug light flash after you crank? If not, you have
more than one out.

Sure! You have exactly one good GP left. One (0.9) may be marginal.
An ohmmeter is not the best GP tester out there, but it is common

Did you isolate them electrically, either by unplugging the multipin

I measured resistance on all the glow plugs and they are all reading
0.3 ohms on my little Radio Shack digital multimeter.
You did remove the plug from the GP relay before checking
the five GP resistances? If you don't they're all in parallel
and a bad one won't show up. Such low resistance is
