Peugeot 207 1.6HDI - P1351: Accessing & Identifying Relay Type, Removing Headlight & Reflector

Question

Hello.
As in the picture attached, I have a problem with the lack of candle power.
Diagbox informs that the voltage reaches the relay, but the candles do not.
Question: how to get to the relay in the easiest way?
The relay is located under the left reflector.
Is it necessary to dismantle the reflector? Can the headlight be removed without unscrewing the bumper?

Is this relay semiconductor or electromechanical?
Can you open it?

You will not find them here. They are at the rear of the engine, from the side of the bulkhead.

In C2 I downloaded the bumper and the lamp. the relay can be cut inside the electronics and relay. In my case, "contacts were sticking together" and milked the battery at a stop, so I fixed it.
If you do not undress it, you will not know.

I understand that you did not measure this tension, only you trusted what displays the diagnosis - and this is not true. Check the candles from the intermediate connector (a few cm from the candles) this error informs about the malfunction of the candles.

That's right. Not making voltage measurements. Thanks for the hint. I will check the voltage at the connector. Where is the connector located? Under the air filter housing?

Doktorr · Answer

The efficiency of the candles is measured on the candles with a measuring ammeter or by disconnecting the candle connector, each candle is checked individually. If the cables go individually to each candle, the measurement can be done by unfastening the cube at the relay, eg by supplying a plus from the battery through a bulb, eg 21w in the direction of a candle.

Luckskywalker · Answer

There are individual wires for each candle, why do you need to dig into the relay at this stage if the problem is probably in the candles themselves? There is a 4 pin intermediate connector where you can quickly sprinkle it. If there will be ok then you should go to the relay. The connector is located from the spark plugs towards the timing. Check the resistance and current consumption of each spark plug.

A question to the founder of the topic. You solved the problem?
I touched the candles, two exchanged, the error still. I've called up the beam - all transitions are. I do not want to blindly exchange this relay because it is almost PLN 200, but I see that there will be no other way out.

Please, indicate in my photo where there are glow plugs and cables for glow plugs.

How should I get to them best?

You have to take out the air filter with the packaging and possibly the manual fuel pump. Access weak.
