Peugeot Boxer 2.2 HDI - Error p15BE diagram or consultation needed

The vehicle is as in the subject, 2014. I know that the problem may be in the cables, the spark plug in the fuel vapor valve, the relay, etc., so I'm digging around, but a bit in the dark because there is no diagram. The candle has a measured resistance of 1.2 Ω, so it turns out ok. In the harness I found a melted black wire going from the BSM plug to the spark plug plug. As I remember, there was over 12V on the yellow one, which also goes to the spark plug plug, after the ignition was turned on. Once I fix the harness, I'll check it again. There is no positive voltage reaching the relay's working contact legs.
Does anyone have a diagram or can tell me how it works? Jumper has a similar solution, and Fords have the same solution.
Is this candle in the DPF supposed to initiate filter burning by igniting soot with fuel vapors?

Check fuse no. 5, maxi 20A, in the fuse box.

It is functional and powered, the relay is also functional, I can control it from the diagnostic device. One working contact is connected to the wire going to the candle, but the second working contact is not powered, so there is no connection to the fuse, Damage to the cassette, or is there something else between the fuse and the relay? They often write about it as BSI or BSM, it detects disconnected components, so it is not an ordinary fuse and relay box. For example, the lack of a candle relay, i.e. the lack of a coil on the control contacts, generates the P15BB error.

Did your friend deal with this problem? I have the same error. Today or tomorrow I will be replacing the fuse box under the hood. I'll let you know what the result will be.

I also have error P15BE-73 P1490-92. Has anyone managed to find a diagram or a specific description? Did replacing the box help?

Has the above issue been resolved? because there is no answer, and I have the same problem in Citroen Jumper 2.2 from 2014. Namely, the DPF (particulate matter) light and error P15BE. I cannot locate the fuse and relay for this fuel metering system.

Small additional box in the box under the hood, one red relay and one fuse. If it is OK, disassemble the dispenser and wash it very thoroughly. The fuel must flow freely through it.

And where is this dispenser located? so that I can do it tomorrow.

Access from the bottom, right in front of the DPF.

The fuse next to the lamp was burning. There are three of them next to each other and the one in the middle was burning when I tested the spark plug relay program (or whatever they call it). I disconnected the plug at the bottom from the spark plug and connected the bulb, which was flashing on the test and the fuse was not burning. It couldn't be simpler. There was a short circuit on the spark plug itself due to rust and it could not be repaired.
My friend replaced the entire element of this candle, the price is PLN 850 for a new one.
After replacement, automatic firing occurred because the system was functional.

A question for my friend decibel91: where exactly is the box with the relay and the DPF injector fuse located? Maybe someone else solved this problem with the P15BE error, the check light is on after removing the error and turning off the car, the error returns after about 5 minutes, the car drives normally, the injector was replaced with a new one, there is voltage on the connector.

In the box under the hood, it looks like an added fuse strip.

Yes, but I only have a relay there, when I disconnect it, the car does not start.

Bridge the relay and see what it turns on.

I see an old topic, maybe someone can help. I have the same error, but the problem is that there is no current on the cube from the spark plug at the DPF and when the car warms up, it loses power and this error appears. I will add that when I disconnect the cube from the temperature sensor, the car has power. Boxer 2.2 HDI 2013.

My 20A fuse under the hood blew, the error was cleared, and everything works.

Gentlemen, perhaps someone will know.

I have the same error.
P15BE
The fuse was blown, I inserted a new 20A.
I replaced the T20 relay
I replaced the injector.
Still the error comes back and the engine enters emergency mode.
I checked on autodoc, as soon as the computer wants to apply current to the plug (new), zero response. I connected an H7 bulb in place of the candle and a meter. No current arrives at all, not for a second.

Somewhere someone described that they plugged a wire from a 20A fuse from the 5th injector into a T30 relay, but I can't find information anywhere on what the T30 relay is from.
I'm about to tear my hair out....

I have the same problem with the fuse for vaporizer blowing regularly and P15BE(73) showing on diagnostics.
On closer look the wiring harness under the fuse box has been badly melted. I'm guessing the vaporizer went faulty causing high current, just not high enough to blow the fuse immediately, so the wire got red hot. The wire supplying the vaporizer glow plug is far too thin gauge and doesn't look like it would handle much more than 5A never mind 25A which is needed to blow the fuse.
Now there's just a mess of melted insulation and several fuses are popping!
I'll try to replace the melted wiring and see if it comes back to life!
