w115 glowplug system?
It's a new to me car. It has a 617 with the old style loops glowplugs. I should have checked before I ordered new plugs, I would have ordered a retrofit kit for the newer pencil style.
It's got 5 new loop style plugs.Dummy light still does not work. How often do these plugs come bad from the factory? Where's the relay and fuse located for this system?

The relay is under the dash on the left side of the sterring column. It's an aluminum box about 1" x 3". Can't remember where the fuse is at the moment or if it has one. Try checking that the wire coming off the #1 glowplug has a good connection to the big round sensor between #1 & #2 glow plug. If it doesn't the light will not come on. I'd say the chance of all the plugs being bad from the mfgr are very low. Good luck.

Is it recommended to convert to the newer style plugs? Is there much to the conversion?

Whole kit includes a new relay and jumper wires. I see no need for a new relay so I think it's better to just buy the plugs individually and make up 3 or 4 short jumper wires. You get faster hotter glows with pencil plugs and no wasted heat escaping to atmosphere via the heavy resistance wires.

Excellent...when I bring home the 115, this will be one of the first enhancements.

the big round sensor is the temp sensor for the GP relay.
The interior I have is light brown, has all the door panels, B pillar and rear seat cover. Front seat covers are gone. Sorry, no right side mirror.

I heard that by doing the conversion to the pencil type, that they don't last has long has the old style. Is this true? Is there a big difference between the two?

My retrofit pencils have been working for 6 years with no problems. BIG difference in very cold weather.
In fact, I have a Perkins 4-108 diesel generator in my motorhome with loop plugs and I'm wondering if there is a retrofit plug available for them I like them so much.

The new GP relay has a temp sensor or the W115 itself has one? The W115 is all manual so a temp sensor would be a moot point.

actually the W115 300D was automatic used the same type of relay as the early 123s. I didn't know it until I bought one, I was expecting the gorilla knob like my 240. The GP light is at the base of the speedo.

Right I missed that one. Monomer didn't have the car listed, 617 was the key. I have both too and I forgot about the time. I am having my OM617.910 transplanted to replace my tired oil burning 240D motor and would like to convert it to fast GP relay. The funny part is that it will have a hybrid GP system since the IP is vaccum controlled and not cable shutoff so it has to have the 300D keyed to it.

Are you talking about the 'salt shaker'? There are quite a few variations of W115 glow plug systems... some with relays, some without. Do you have a gorilla knob for starting? We really need more info on the car to help you out.
I've had several W115 220d's with salt-shaker indicators and no glow plug relay (gorilla knob). The salt shaker doesn't glow real brightly and it takes ~45 seconds to get even a faint glow. When I first got the car(s), I thought this indicated glow plug problems. However, after a lot of troubleshooting (including glow plug current measurements), I found that the indicator didn't affect or indicate proper glow plug operation. When I upgraded to parallel plugs, I bypassed (i.e. shorted) the salt shaker indicator.
