wont work with diesel cars

ObD2 and check for oxygen sensors and filters.

You need to read the codes. Try asking on peugeot forums for advice about a cheap code reader.
Worst case you'll need to pay a garage to read them.

What sort of driving do you do? (short or long journeys, fast / slow)

The car barely gets used since we have a smaller car which use around the city. When we do use the car it's for long journeys. Saying that we do start the car everyday and make sure it's maintained well

Starting it everyday and not using it would be a bad thing. Stop doing that.

Pollution fault will typically be DPF/FAP or EGR - both of those are likely to get gummed up if you are doing lots of cold starts and will be expensive to fix.

As you have the warning up I would get out onto a motorway and do a 30 min run at highish engine speed to make sure that everything gets up to proper running temperature.
Is this one of the ones that needs Eolys fluid?

You can pick up a clone of the proper psa diag tool for about £100 but you need a laptop as well to run it on and to be confident to use it.

Dpf is goosed very common on this model of car

Most probably dpf or egr fault or even both.

Again, rubbish.

It gives the same for my current diesel as it did my previous petrol (which is everything!).

Its the same for petrol engines, you get very very basic information out of the port on new cars. They just don’t have the ability to read the non standard PID’s.

Thank you @adam_holcombe‌ @ding‌ @jr007‌ @mas99‌ @123batman321‌ @.MUFC.‌ @Dannyrobbo . I have read up on the diagnostic scanner some people it doesn't work on the diesel cars on other website but I'll buy one and give it a go. If not I'll just hit the psa diag tool however does this tool work on all cars ? Or is it model specific ? I'm going to go on the motorway to anything out for another an hour or so. But thank you all for the amazing help and I appreciate it a lot.

It's very likely you will need dealer level diagnostics for the dpf fault, A basic code reader would probably still give you a fault code for any egr fault though in my experience that is.

having had two 307s years ago both had these faults, even dealers couldn't figure out what the issue was, they were on the verge of putting in a new engine in one of them and then backed out because of the warranty expired only to decide 6 months later after threatening to take them to court and then selling the car they would still replace it. I would suggest finding a good specialist and getting them to look at it.

Psa Diag will be as close as you can get to dealer level, why can’t you just take it into a garage for them to hook up? You will get a diagnostic message but it isn’t going to be definitive and say replace .... it’ll still need further diagnosis from a garage or yourself.

I have been to many specialists they can't figure it out. They can't find the exact fault. They are just guessing at this point.

The problem is that most 'ordinary' garages don't have the dealer level tools. They'll have a generic thing or a snap-on reader, but having dealer level diags for all brands is v.expensive. I know that around me the small garages all seem to use the same diag specialist - basically, this guy has a van full of electronics and goes around the garages doing the complex diag stuff for them.

I have in the past had a tech 2 (saab/vauxhall/opel), vag-com (vw group) and PSA Lexia kit because I do my own work and it saves me a fortune compared to using garages.

The tech2 was a genuine unit with the cards for Saab and GM and cost me £500, Vag-com was £200 and the lexia was a clone £120.

The real issue is that modern cars with high pressure systems are quite complex and many garages simply don't understand the detail of how they work. I found this to be especially true with the PSA HDi stuff which is very good but gets expensive quickly if garages just throw parts at a problem they only partly understand.

They should at the very least be able to tell you what codes they've found. If it is FAP/DPF then what happens when they try a forced regen?

if you then have tried the dealer and they saying the same which is what happened in our experience then its probably time to trade it in or if its not in limp home mode and still has power like you said then just ignore the lights but not sure if it would pass another MOT with them on. We used to love Peugeots, had the 205 GTI back in the day but wouldn't have one again because of the experience with the 307s and sadly even new ones have the same fault read a long term review on a car site last year and their had had the same light and back and forwards to the dealers

Lot of good advice above. I recently had EGR and Throttle Body issues on a Citreon and the local garage (and on my own OBD reader) could read the basic faults, but a Citroen specialist independant had the kit to read the errors with more detail and was able to cross reference with Citroen service bulletins. A good independant specialising in Pugs is probably your best bet.
