Too bad it was only officially registered as Euro 4

Today I'll ask the mechanic if he can install an EGR/coolant heat exchanger from the newer model while he's fooling around with the engine.

Does it require ECU inputs (did you see wiring running to/from it ?) , or is it working all the time ?
If it's always-on, it may be possible - wether it'd pay for itself is another matter.

Adding a DPF is out of the question, until a retrofit kit produced.

Non-regulated DPFs are not very effective.

The block heater finally arrived



From the instructions it appears that it is not mounted in the block's freeze holes, but there is a special port for it in a plastic coolant housing behind the engine. This technically makes it a coolant heater, but also eases installation.

Yesterday I installed a piece of coroplast between the radiator and intercooler.



This supplements the two-part grille block and should allow cooler air into the cylinder while keeping the engine warm.

The EGR/coolant heat exchanger has no wires, so it's the easiest mod (unless cooling the recirculated exhaust gasses will make a sensor somewhere else go bonkers). It looks like this:

I'm sure that a DPF in Mr A's ride would be kept quite clean...

What make & model is the heater ?
It might fit or they might do one for my V50 as well - I can't use it unless I have the car garaged though (it's sleeping outside).
Volvo wants a ridiculous amount of money for a block heater.

I wonder if I already have that cooler, or could get it installed.
Which Peugeot models have it ?

DEFA 412512. It costs about 100€, I got it for 90€ through a mechanic with a discount (my brother-in-law). But you should have an extra 50-100€ ready for the cables/connectors from DEFA

I'm willing to bet that you do, since it seems to be paired with the DPF. My 307 left the factory for southern France in May 2005, one of the last pre-lift units (so I have a few post-lift details, eg the electrical system is CAN-CAN instead of VAN-CAN, whatever that means). I don't think I've seen a 2007 or later 1.6 HDi without the EGR cooler, but I have seen earlier models with it (not only Peugeots, but also Citroëns and Fords). I'm not sure whether there were cars with a DPF but without an EGR cooler. It looks like this:



Here's the back of an engine with an EGR cooler:



And one without (like mine):



(The arrow shows where I think the heater goes.)
You will have to look at the back of your engine. Almost everything is in the back, and getting there is a Royal PITA, so a mirror will help after you've taken pretty much all the ducts and filters off. The EGR cooler I ordered cost 50€ used from a Peugeot 307, but the exact same cooler was available for 60€ (Citroën C3 1.6 HDi) or 70€ (Peugeot 308 1.6 HDi). Now that's marketing!

I've started a new thread on cooled EGR, where I (and hopefully other members) will add more details about the benefits of EGR cooling.

[Piwoslaw]

I used the coolant heater for the first time yesterday: the outdoor temperature was 10°C, the engine temperature after 30 minutes of heating was 24°C. So whenever I can, I'll probably start preheating 1.5-2 hours before taking off. I wonder how much over ambient temperature I'll be able to get?

What are you saying, my foot is heavy or my car is dirty ? How very dare you. However I suspect you may be correct...

I'm watching, but I'll happily live without it for now.

Mrs A is possibly going to renew her Octavia in the new years and a non-DPF spec is part of the search - much more of those available...

I'm not sure of the wattage of your heater but i have a 1KW heater that is pumped through the engine. After 2 hours it gets up to 55c, maybe a few more if it's not so cold. I have the option of making it a 2 or 3KW heater which would heat it quicker and lessen the time it has to dump heat as an alloy block loses heat very quickly!
I have to go now, my kid has gone to bed telling me he has plans to make a zombie garden tomorrow!! I may be busy making tombstones etc.
Not with coroplast though.

[Piwoslaw]

My heater is only 550W (Kill-a-Watt-oid says 519W), it was the only one I could find for my engine. It takes its sweet time, but that's much better than nothing. Won't help much on short notice, though
I did start wondering about adding a small (~5-10W) pump to help move the coolant into the engine block before it cools, and/or insulate the section between the heater and the block. The latter wouldn't be too hard if only I could get my hand that deep behind the engine without lifting it out of the car

I guess the next step would be to find a small heater that replaces the oil pan's drain plug.

Dead neighbours work the best.

According to A Jnr just now.
