Guessing its the lower power 2.0 as it looks like this with 2 separate sensors, and reckon the one arrowed is the pressure sensor

Yes that looks right. Here is an example of a 1920CZ used on that engine: 1920CZ - Sensor, air pressure sensor OE number by CITROËN, PEUGEOT | Spareto

If I’m not mistaken the 163 hp engine is the twin turbo 2.2 version, which are quite rare in Oz. Take a look at your VIN. It should have “RHR” in it, which is (one of) the engine designations for the 136.

Peugeot servicebox lists the 2.2l HDi as 175. I think that's PS metric HP

I thought it might be interesting to post what my version of servicebox shows for the 407 engines. The first screen shot is from Servicebox and the second from the wiring diagrams section (SEDRE). One confusing thing is they list the engines differently. They both show two engines: DW10 BTED with and without FAP and DW10 CTED. The engine power specification seems to differ slightly to the figures I found on the internet:
DW10 BTED4 / RHR 136PS (100 kW, 134 HP) with or without FAP
DW10 CTED4 (DW10C) / RHH (165 PS (121 kW, 163 HP) with PEF

Does anyone have a pinout for the glowplug relay? Just so I can test plug resistance from the relay instead of trying to get to the actual plugs. Resistance values would be good too?

I have attached a wiring diagram which I think is probably about right for your car. The wiring diagrams vary according to the RPO number (this should be at the top of the tyre pressure label near the driver's door hinge) but I think the glow plug relay details on the diagram should be right. The resistance of the glow plugs should be no more than 6 Ohms. They are 12V heaters so in fact I would expect them to be much lower than 6 Ohms when cold.

The errors you have so far disclosed, to me, don't suggest it would stop your engine starting. I am wondering if the anti-theft might be engaged or at play ?

To add to RedSectors suggesting. Once you get DiagBox working you should look at the immobiliser in both the engine ECU section and the BSI section. What sometimes happens is that the key's transponder works okay so the car passes the beep test but the engine ECU doesn't receive the unlock command from the BSI. This fault does not generate a fault code.

Engine control unit locked?

That's is what I feared the engine ECU should be unlocked. The transponder label recognised tells me the key is being recognised. There should be another screen relating to the engine ECU which shows that it's waiting for a response from the BSI.

Thanks again Ian, didn't get a pic but in the engine ECU it said it was fine. Have to bear with me on the diagbox thing its all new to me. Used to vagcom and generic readers.
Anyway battery has finally died so its removed and on charge for another bash at it tomorrow.
What does 'economy mode active' mean? Keeps flashing up on the screen in the middle of the dash wonderer if it was relevant.
Also diagbox shows the same 2 codes that have appeared before. Didn't get time to pull the sensor or check the glow plugs (neighbours car and tend to be busy with my own stuff)

Thanks for the help all much appreciated

Don't worry about economy mode. It just turns off the less important things to save battery power. It comes up after 30 minutes if an accessory is left running or if the battery drops below 10V. It will clear when the engine starts.

In the case of the engine ECU diagbox result does is show waiting for BSI?. If so that is bad, it should say unlocked.

Definately didn't say waiting for BSI mate, pretty sure it said unlocked.

That's very odd because the BSI data is saying it's locked.

 

[Wacky7791]

Once the battery is reconnected it'll likely start, run for a few seconds then die and not start again, this has happened twice before.
Be interesting to see what diagbox says has a fault before trying to start it the first time.

Record/upload the run, might help us work out what is going on.

 

[Wacky7791]

Would love to redsector, can you advise how to do this?
