Just as a thought on current, if each of six glow plugs drew 25A, and as they are in parallel, the total draw would be 150A, which would require a cable of 1/0 or 2/0 feeding the relay. Does that correspond with what is installed?

Can an extension be made?

GP would draw current in the order of 10-12A when hot.

I would T the wire off the GP relay big plug. Open up the big plug. Lift the pin connector and insert a new one for the dummy plug(s). It is easily reversible.

He may not have to take the old wire out. He could unplug from the glow plug relay the wire to the bad glow plug and just use a different wire in its place that would go from the relay to the dummy glow plug or resistor. On second thought, I don't remember if one of the wires can be separated from the six wires that plug into the relay. It's worth checking. |

This BS is the only reason I bought a 97 instead of a 98 or 99. Pre 98 diesels are exempt from smog.

What year is your car doesn't help the OP. You are stating the obvious.

Not that I'd recommend this, but I'd think that if you bridge all the glow plug outputs in the glow plug relay it would think everything was fine. Note, if you do this you'll lose the circuit breaker protection on each glow plug circuit.

I agree that an external glow plug is the best load. Any resistor that fakes it would need to draw similar power and thus also glow. Screwing it into a metal tube is the best idea, to manage the heat. But, the suggestion to bridge all the glowplug wire pairs together might be simplest.
First time I heard of this big problem that glow-plugs get stuck in the head (aluminum?). Perhaps M-B installed them w/o anti-seize on the threads. Stuck spark plugs in aluminum heads is a similar problem. Sometimes removing one shears the threads in the head. One reason to remove and anti-seize them before their 100k mile lifetime. I can see smaller glow-plugs being a bigger problem. The 1990's M-B diesels look nicer and perform better than my 1980's clunkers, but I read more horror stories about serious maintenance issues.

So one ohm. The resistance is very important, not just to calculate the current draw of a resistor, but also because the relay compares the resistance of the GP's and will only turn off the CEL if they are nearly equal.

The GP current has to be 15 amp max at steady state ( when hot ) as the fuse is rated 80A or there about for 6 GPs. That is why putting a 0.5 ohm 50W resistor is a BAD idea as the resistance of GP varies with temperature.
