Dpf is goosed or needs fluid topped up

Sounds like the de pollution filter. Have it checked at a Local garage of run a fault reader on it the part is expensive but if you search around you may find it cheaper then a main dealer
#3
'anti pollution' faults are a generic warning in Peugeots, it can mean anything. you need to do a diagnostics
#4
Looks like this is a common fault judging by Google. Get onto a Peugeot forum ASAP as there are a few possibilities but joining a Peugeot forum will help avoid unnecessary and costly expenses and point you in the right direction according to your capabilities.

I spent fortune on my Renault for a similar fault try cheap things first.. mine just needed a filter changed.. it was meant to be done at service and not changed so that was problem.. occurred few months down the line.. before I diagnosed this garage changed fuel pump and £6 fault cost me over £300 so do cheap stuff first...

This happened to me, but the car still drove fine. It was an error and the garage just reset something and it hasn't happened since.

You can buy your own OBD2 fault reader off ebay very cheap (less than £10)... Free apps will give fault codes and you can start to look into it once you know the fault... With the apps you can buy the premium version and they let you clear the fault in case it was just a glitch.

Sounds like an egr valve issue - if it's a known fault try to get the dealer to pay 50% as a 'good will' gesture.

they usually do free check ups most smaller garages these days so just ask them before they do it pointless paying for it given how ready and easily it is to buy the obd2 readers. some still try rip people of buy trying charge large amounts like £20+ quid for it.

EGR valve i bet. get it deleted!
A slice of EU Red tape in your engine bay, that they dont contribute to the cost of when it goes wrong.
An EGR valve is like your appendix. The car doesn't need it to run and all it does is cause problems.

Whatever the problem the garage will blame supermarket fuel.

What Adam says, but I feel your pain. I had exactly the same problem with an 08 plate 308 Sport diesel after ~5yrs. Happened increasingly often. Would start again after 10 mins or so (of trying, but I had a couple of scary moments when it lost power in the fast lane of a motorway). Could usually clear the error light for a bit by forcing a regeneration.

Replacement DPF options were £700-£1000, but had to do a diagnostic first ... ~£60. They (Pug dealership, generally very good) decided it needed a different part (can't remember what), to the tune of ~£500. Did that. Problem cleared - for all of 3 weeks, then back to the same problem. Decided to trade it in after that, as I could just see good money going after bad, and decided it was also too dangerous.

Never going back to diesel: I had even worse luck with a 1.9HDi Renault Scenic (from new). You name it, it went wrong.

Apart from that one, Pugs have always been pretty good to me.

Good luck with finding out what causes yours though.

Remove the egr plug. It will give an error after a few starts but shouldn't put you in limp mode. May give you a clue where to look.

It will most probably be a fault with the dpf or the egr. The best solution would be to have the dpf hollowed out and remapped, When remapping tell them to write out the dpf and egr. That problem would go away and you'll get more power and mpg.

DPF hollowed out = £60-£70 labour, Remap = £150-£400 but you'll probably get 10%+ fuel economy so recoup the cost eventually and never suffer any dreaded dpf or egr faults again.

It might also be a good idea to clean the egr out because it could be stuck open, remapping wouldn't help if that was the case. Removing via remap just prevents the car requesting the egr to open at certain times etc.

It will still pass the mot so long as the dpf is in place, they will check visually hence hollowed not removed ;).

An auto electrician might be a better option than a garage for diagnosing the fault.

Cheap obd scanners are useful but they will only usually read the ecu, Some codes require dealer level diagnostics. Just because the cheap obd scanner doesn't detect a fault code it doesn't mean there aren't any ;) as I've found out in the past.

Just a quick update for those whom took the time to reply. Took it the quarter of mile to the garage this morning half way there totally conked out had to be towed the rest of the way. Rang the garage this afternoon said diesel was empty had put some in and the car was running fine??? Rang me back 20 mins later to say it had a diesel leak. Just rang back again saying got a terrible leak somewhere at back of engine and currently stripping bits to find the leak and this is the probable cause. So ring back again tomorrow
