E 320 cdi 2004 won’t start

[Broadleybenz]

Hi, I’ve got an e320 cdi and it just won’t start, coil plug light doesn’t come up at all so there’s nothing happening, won’t crank over. But when the coil light does appear which is very rare the car starts and stalls a few seconds later
Any ideas?
Thanks

Do you get any ignition lights at all when it doesn't crank ?

I actually had this happen to me on a W211 and I had to use a jumper wire to start the car which at least keeps you mobile. I sold on my car in the end so never managed to resolve the issue.

When you say jumper wire?

The RAC came out to me as the fault had left me stranded whilst taking a break at a service station.

They left me with a pair of wires under the bonnet by the fusebox that I had to twist together before starting and then disconnect after switching off the car. I later extended those wires into the cabin to save time.

I can only assume that those wires were hooked into the relay socket as per the first video.

first video shows 2 ways? Was it the one with crocile clips or one where you take the relay out

Thank you

 

[Broadleybenz]

Was it the crocile clio way or relay way
Thank you

I believe the relay way.

I believe the relay way.

Does that go from top pin on relay to bottom pin or down side of the fuse? I can’t make it out
Thanks

From top pin to bottom pin.

If you pause the first video on 2:07 then it should be clear.

You need to find the fault codes, but it may be the glow plug relay gone capput hence the occasional time it works.

Do you no which one the glow plug relay is

 

[BlackC55]

It probably wont be the glow plug relay causing this fault.

You need to get it on a Star to look at the live data of the ignition switch. This will show if its getting the cranking signal or not. Its guesswork without this info.

Thanks for your help, also do you know if this year and model was a stop/start?
