The W211 e220 CDI injector plug is being referred to.

Greetings, everyone.
I hope that everything is going well.

May I request a little amount of assistance, please?

While removing injector number 2 from the W211 e220cdi, the wire on the plug itself snapped.

Is it feasible to modify the wiring for injector number 2?
Is it possible to fix or solder it back into the plug?

Any assistance would be much appreciated.
Thank you very much.

Yes, you will be able to get replacement terminals and plug connections directly from Mercedes. The cost will not be high. However, I do not own any numerical data on it.

Thank you for your kind words, dodipops.
The cables will be color-coded.
If I recall well, the interior of the plug consists of two spade-like connections that attach to the injector. The plug itself has a D-shaped configuration. However, the wires on the plug are damaged. Therefore, I would want to know which wire corresponds to either side of the plug.
Will it make a difference if I connect the wires to the plug in any orientation?

Thank you, dodipops and everyone else.
I will communicate with you once more.

You would need tools for the process of re-terminating.
Have you considered purchasing the NO2 plug with tails from a breaker and then re-soldering it somewhat farther away from the injector?

Hello,Bitxx .

I obtained an image of the plug from the internet.

However, the wires on our plug have become detached and are too short to be reattached by soldering. As a temporary solution, two wires have been soldered to the pins of the plug, without following any specific colour coding. Now, when I reconnect the plug to the injector, I am uncertain about which wire should be connected to which wire on the cable loom (referred to as the wires that are supposed to be connected to the plug).
I have not personally seen the automobile; all of my knowledge is derived from my father's accounts.
I will be descending tomorrow, and hopefully everything will go well.
In order to ensure that I am able to make updates, I will need to do certain actions.

Thank you everyone / mate.

Indeed, it is necessary to connect the appropriate wire to the corresponding side of the connector.
Examining the other injectors may provide insight into if the wire has already severed from the socket.

Contact a Mercedes-Benz professional by phone and request their assistance in examining the wiring schematics to provide you with accurate information about pin positions and wire colours.

Indeed,...

In the photograph shown, it is evident that the two wires inside the connection have been detached. Consequently, my father skillfully soldered the two wires onto the pins, incurring no financial expense.
Upon reaching the parents, I found that the injector was there and just required the wires to be connected.
I have obtained a magnifying lens and I am ready to examine the colours of the wires on the original loom. I do not have any jokes or distractions to divert my attention.
I observed them nevertheless.
The colours mentioned are dark green and dark brown.
The colours are dark brown and black.
I inspected the remaining injectors to ensure their proper functioning, as suggested by one of the individuals mentioned before.

Therefore.
The colours green and brown have been or are now located on the passenger side of an automobile in the UK.
The colours brown and black are located on the driver's side.

The car successfully started on the first attempt and is now running smoothly and evenly. There are no leaks.

Everything is satisfactory.

However, in my opinion, that is an unfavourable proposition coming from a prestigious vehicle manufacturer.
The black death refers to the diesel fuel contamination that occurs when it seeps through the copper seal. The coat becomes stuck and obstructs the flow of electricity down the wires to the socket.
I expected that they would have installed a fuel-resistant protective covering around the wires.

However, everything is currently in a satisfactory state.

Thank you everyone for your assistance once again.
Hopefully, this information proves beneficial to someone.
However, please be cautious of the wires as they tend to get fragile.

Wishing you a safe and enjoyable journey.
Thank you.
