A load of government lefty produced bolacks!
Half the diesels driving around now will probably have no working CAT DPF or EGR valves as they just weren't designed to last more than the manufacturers warranty period. So what happens? We poor sods have to dodge around the rules just to stay on the road! Everyone went out and bought diesels as we were told they were better for the environment and the fuel and tax was cheaper. Now they've "discovered" diesels are really bad for us so have been putting up the price of diesel and road tax so the motors we've now got are a bloody liability especially if you live near London!
RAAARRRR rant rant!
Anyway stick a broom handle up that old cat bolt it on and see what happens. I think older cars (pre Euro5 2005 ish) have less restrictions and less tricky engine management systems ie you don't have to map out the DPF/EGR software to keep the dash lights off.
I've got a Vauxhall you know? I've been though it all......

Diesels pollute far more than lean burn petrol, the fuel is more expensive, and electronic management and parts like EGR, DPF, Cats etc etc, very limited lifespan and expensive to replace. Gutting the cat on an older vehicle will almost certainly mean reduced emissions, and better fuel economy and performance. Other than something with the old XUD atmo diesel, simply cannot work out why anyone would want to buy any French diesel vehicle, all of which have issues, many of them very expensive to sort out?

Had several XUD powered vehicles, and while not being that quick they were as reliable as Japanese, as well as cheap to run and maintain. HDI on the other hand is in my view a nightmare, unless you are very lucky indeed and nothing goes wrong............
Now seems that the only place to get the cat for this car is with Peugeot at £250 for recon ones! The ebay seller refunded me no problem and quick to. They were a pleasure to deal with. So I am going to refit the original and see what happens.

Peugeot were making diesels to Euro 4 emissions standard a few years before that was required by legislation. The MOT tests to Euro 3 standard (if that) so diesel particulate filters (dpf) are not required for the MOT (but ideally still have to look like they are there from the outside). I like to remove the dpf but keep the cat as that doesn't do much harm.
You can get rid of the particulate filter and get another 5mpg out of them but you need a remap so the diagnostics don't pick up the reduced back pressure. Not a case of just knocking it out. Get rid of the EGR while you are at it.
@p0689109 find a friendly Peugeot specialist forum as this stuff is car dependant and there is no point figuring it out from scratch. If you want to cut your losses I have a very pretty 180bhp 406 Coupe for sale with all reliability mods done. Has a very helpful specialist forum, 56mpg economy for £750. I just bought a V6 auto version of the same car because I'm getting old and lazy.

If you are sure the cat is causing your problems, then it seems pointless refitting it, without removing the internals first?
Seems a shame you cant get the car to a local diesel specialist though, as its only likely to cost £60 or so to find out whats actually wrong, rather than just guessing.
Malcolm I have joined the "peugeotforum" but not much help there.
I am not sure the cat is the problem and am going to refit it as I cleaned it out as best as a tapping hammer and air line could, and see if a new EGR solenoid valve makes a difference. First I have to get the rear brakes back together as I am having a bit of a problem with a caliper and its brake line after removing to replace the badly worn discs.

The cat needs to be either replaced or gutted completely if its suspect at all.

Maybe you could find the answer on one of the peugeot forums?

Cut it open, remove the core and weld it up again is the easiest way.
Update at last. I refitted the cat(what a pain the clamps are both to get off and even worse to get on. With the bolt removed the opening is not enough to unclip them from the manifold lip and the exit ends lip. It is nigh on impossible to open them enough to get them off. I managed to flip them off using a screwdriver. I had to utilise a brake caliper piston reset tool to open them up enough to get them back on). I then decided to locate the ECU and unclipped the three plugs and removed it to give it a once over. All the pins looked fine and there was no signs of damage or the like so refitted it. Connected the battery and she started up straight away. After a minute or so I gave it a bit of throttle and she revved up past 5000 rpm. Result, or so I thought. So I went back to finishing putting the plastic bits and the like in the engine compartment back to where they belonged and decided to take the car around to a garage that I use all the time. They very kindly offered to use their reader to see whats' what. They have a handheld Snap On unit which worked on the car. Unfortunately when I started up to take it there I found that the fault had returned. Restricted rpm 2800. The reader showed a couple of things, one of which was the glowplug relay was staying energised and the airflow meter. Now the Peugeot forum has had a couple of 1.6 diesels which have had a glow plug go down and that caused it to go into limp mode. So first I have to locate the glowplug relay (anybody know where that is, my Haynes and the Handbook does not consider them important enough to be included).
I had another defect that came with the car and that was the ABS. His reader showed that it was the front right sensor showing no output. So lets hope its just the sensor.
The reason the engine warning light was not illuminating was that on test, using the reader, it showed black! So either the lcd has gone or somebody has black taped the instrument.

New clamps every time on these exhausts. I bunged one on a couple of weeks ago and had to remove it again to cut and weld the tailpipe which was at the wrong angle. Aftermarket rubbish from a supposedly good manufacturer. The new clamp I had was a real hassle to fit the second time.
Don't know anything about glowplugs. My HDi doesn't need them. I did replace the MAF to fix a limp home mode once.
The PP2000 Peugeot diagnostic software (knock off version with the connector box to connect to a laptop for about £50 on eBay) is a must for me. I don't know how you can fix problems without that - the cars are always going wrong but rarely break down so you just diagnose with PP2000 when you get home and fix at the weekend. Sometimes they fix themselves the next day. That makes old Peugeots very cheap to buy. I just bought a 15 year old V6 to replace my HDi. Loving it. I plan to keep it long term as a classic.

I know what you mean about those exhaust clamps - a really stupid design. You can spread them by putting a long bolt through the hole where the clamp bolt goes with 2 nuts in the gap in the clamp. Screwing the nuts in opposite directions will force the clamp open.
If I come across one of those clamps on my cars they normally go in the scrap bin and I fit a standard 2 bolt clamp in its place. They're only a couple of quid and a whole lot easier to fit.
Before you go replacing the ABS sensor check the toothed ring on the drive shaft. Some of the rings are pressed on to the outer cv joint and they can split due to corrosion and not spin with the drive shaft. There are new ones on ebay and are simple to fit but you need to remove the drive shaft. If you need to fit a new sensor good luck as it is a pig getting the old one out.

Further invest shows that the culprit could be the airflow meter as running it unplugged allowed the engine to rev normally. When the garage read the data, as well as the glow plug relay, they mentioned that the air temp in the airflow meter was flagging up to. According to a chap on the Peugeot forum unless the car has DPF the glow plug relay will not cause the problem. From what I can gather that system is best left alone as the plugs are a nightmare to get at and to remove in one piece. The relay is a price too. Looks more like a contactor than a car relay too!
That's funny I'm usually removing standard 2 bolt clamps and throwing them in the bin and then fitting the single bolt design as they clamp up so much better. Of course that is only my opinion and you all know what they say about opinions.....
