I used needle nose pliers and pulled from the smaller part of when the ignition is on no 2 the glow plug does not light but when i start the engine light turn on for about 1min. Going back to other comments about checking fuses and burned out tracks in the relay box itself, the unit seems to be sealed and have no place to open it up for inspection. I have made sure that the solder joint is strong and goes completely round the remaining link not just on the top for strength has good continuity and it is a goog strong solder joint but it doesn't just pop it open it blows it a good 4mm open. The only problem is it's brand new. A digital multimeter shows the exact number result of the test. Also lather the plugs with anti-seize before reinstalling. You have the potential to get into My check engine light is on and also the glow plug light.
This is the number 1 plug. I just re and re my injectors today for cleaning pattern and pop testing. I had one go out on cylinder 4 too curiously and did all of them. Here is a pic of how the wiring works. I even think I can feel and hear the relay make contact. So on to the glow plugs.
Hi I have 2006 e320 cdi with 90K. The plugs that were bad came out pretty easily. I have the Beru plugs and plug out the plug no problem. If you suspect the relay is bad in your Mercedes, unless you are a mechanic, you may have difficulty finding it. Thanks guys for answering, I've been on it again all day i have repaired the No:4 glowplug link in the relay 5 times, even though I have replaced the bad glowplug and all plugs read ok for resistance when I start the engine after about 3 seconds the No:4 link blows again and the lights stays on.
Eventually it will pop apart. Searched glow plug testing and got resistance ratings all over the place. Connect the other end of the other lead to the battery. This is only a problem on engines with the long glow plugs the older short ones Thanks houseofdiesel for that useful info I figured if I was going through the labour of pulling all that stuff off the engine and actually pulling the glow plugs it would make sense to just put new ones in and be done with it for years. A stuck relay, and me forgetting to remove the key, caused the car to not start. Under the influence of increasing heat, the inherent resistance of the glow plug increases and will limit the current to approximately 8 amps.
Once all of the glow plugs have been located, disconnect any wires or caps attached to them. Put the black on the battery ground and the red on the battery Red just to check and make sure you're measuring 12V. These wires are attached to bolts. When they don't work you are going nowhere. And if so is is a simple repair or something easy The I just did my glow plugs 2 weeks ago and it was very easy to do with the proper tools. After replacing the fuse and turning on the ignition to the glow plug cycle, I checked to verify that I had power on both sides if the fuse.
If the winters get as cold as they do in here in Minnesota, you will like knowing that your glow plugs are not going to crap out when it's 40 degrees below zero. I have even vacuumed the relay in case a bit of solder or the original link shrapnel was floating about some where out of view and shorting but there is no short showing in any of the leads from relay to plugs but after it has blown the link when I start it again although I can't see a spark I can sometimes hear a quick crack and then it carries on running. Tired of messing with your old factory relay or maybe you are tired of having to pull a lever to light your glow plugs. It is located on the firewall in a small plastic holder. A multimeter is a black box of electronic circuitry used to test electrical wiring or devices. You could un plug the connector from the relay to right side of engine compartment towards the front with 4 wires leading in trunking to the engine and test 12v being delivered out of relay. Terminal 50 provides only 10.
This fuse was burned in half, so I replaced it with a brand new fuse. I bought a Bosch replacement plug that looked a bit different on the tip and had a White stripe around the top of the plug instead of a red one. An analog multimeter is harder to read because every possible result is listed at the top.

A few squirts with Blaster rocking it back and forth it finally budged. However if they are not, or this task is not something that you feel comfortable taking up on your own, this is a service that any professional technician, such as one from YourMechanic, should be able to perform quickly and easily. I have just replaced my glow plugs. If you strip out the potting compound, the relay housing clicks apart. The pencil element is heated indirectly by means of a heater element.
Also as has been said before make sure to get the 5v glow plugs from Beru. Replacing the glow plugs as a set before I sold it solved the problem. A digital multimeter shows the exact number result of the test. Since I changed the glow plugs the glow plug light never comes on when I insert the key it comes on after the car is started. For example, if your plug's resistance measured.
