They are a good engine, this one is still going strong. I change the oil every year or 10,000 miles whatever comes first, 10,000 miles is about 16,000km. The proper fuel filter housing tool is a very useful thing to have, i now use one and find it very useful on this design of filter housing.

Your comment after going through google translate: "Peugeot 406 engine is not the most successful in all respects" Fair enough, most engines are not the most successful in all respects. There are more economical engines, there are more powerful engines, more rev happy engines and so on. The DW10ATED was and still is one of the most reliable modern diesels, along with the VW PD diesel. Before diesels became too complicated, it has the right amount of technology in the form of common rail fuel injection to make it responsive and nice to drive but the parts were sourced from bosch and it all works quite well providing reasonable fuel economy and reliability. I can attest to the reliability of these engines as i have had this car for 10 years and it has been very reliable.

@@peugeotCitroen2CV he wants to say that peugeot's engine 2.0hdi is one of the best engines.

+peugeotCitroen2CV EGR If you remove it, or rather just perekroesh passage to the vacuum valve, the car will fly at the lower levels is very noticeable difference !!! Developed by it as if for pririrody. (Ignore the exhaust gases and soot into the engine again, hurting the motor !!!) But! some say that it makes a turn to him well, and you need it !!! all this hype and marketing !!!

+SergioMatiyek Ah right, blank off the EGR valve? I had the valve blanked off for a while on my car, did not notice any great deal of difference in power or economy (although on other cars the difference is more noticeable) what i did notice was that it took longer for the interior heater to warm up mainly because the exhaust gasses on a 406 go through a water jacket which seems to heat up the coolant quicker, with the egr valve blanked off this took longer so i returned it to normal. The DW10 isnt too adversely affected by its egr valve, its more of a problem on the DV6 engines.

this doesnt work for me actually. my car doesnt start up anymore, i think it doesnt prime the housing at all :( i dont know what to do…

Wise words indeed, although some WD40 and cable ties must also be considered haha

It is an interesting statement, although one wonders what it is more elegant and powerful than. A renault clio that would be true, although a Jaguar X308 XJ8 it may be less so haha.

Its something that you can do if the diesel might contain water, I've emptied out the fuel filter housing a few times to clean it which deals with the water, although I've never noticed any water in the filter housing when doing this, but i do get my diesel from the same texaco filling station and drive it every day which might help keep the water out of the system. If you want to drain the water out of the fuel filter there is a screw at the bottom of the housing.

Thats a strut brace it was added after the car left the factory, dont know why the previous owner did this but the car feels tighter in the corners than a 406 without one fitted, the difference is only slight.

EGR Cleaner

Thanks for the comment

they could be cleaned with an airline if ever the filter was clogged and you needed a quick fix to get you home, but i wouldn't recommend it as an alternative to a new filter, filters are cheap enough anyway.

peugeotCitroen2CV Perkins the diesel engine people, reckon that air filters can be used three times if they are back-flushed with air. One also needs to check for pin-holes.

Yes some vitaras got the dw10

the only down side of these engines is speed they are slow and loud and offcoures a on great side is almost excelent fuel economy

vladimir bali In the 406 its quite smooth and quiet (although it does have quite a bit of sound insulation in it), and with a remap youd be suprised how quick they can be, its a big lazy engine under no stress in developing its power so other than changing the oil, filters and timing belt it should do 250k miles no problem.

Je ne passe pas beaucoup de temps à lire diverses huiles. Mes facteurs moteurs locaux (magasin de pièces) recherchent l'immatriculation de la voiture et me donnent l'huile qui convient. Si je me souviens bien, ces moteurs 2.0 HDi prennent 10W-40. Cependant, comme vous parlez français, je suppose que vous êtes dans un climat plus chaud qu'en Irlande, donc la viscosité exacte recommandée peut être différente, c'est dans le manuel du propriétaire de la voiture les viscosités recommandées pour différentes températures. Cela dit, tout 2.0 HDi ou même sur les moteurs XUD, je mets simplement 10W-40 sans problème.

Hi there this was the HDi 110, the 110 denoting its Brake Horse Power BHP, that seems to be the unit we use here, and the one my head can grasp haha. Although a google tells me that 110bhp is equal to 82 Kw, not sure how the 406 2.0 HDi was marketed in countries that used KW as we had the 2.0 90, 2.0 110, and 2.2 136.

They are all TU engines and i think most are grand, the 8 valve ones are the only examples ive worked on. My mum owned a 1.5 diesel years ago it was very economical but at the same time it was an old school diesel ie slow and noisy, needed the head gasket done once but other than that it gave no trouble. The 1.1 is economical enough and in the 106 still great fun to drive. In anything bigger the 1.1 feels underpowered.

Oil grades and types has never been a subject ive paid much attention to, i am aware and fully appreciate that there are usually specific oils for specific engines but do not make any efforts to memorise it. Any decent motor factors can look it up from the vehicles registration and the cost is generally competitive with online prices. However the old 2.0 hdi is a fairly hardy engine, its a lot less fussy about its oil than the likes of the later 1.6 equipped with a DPF which will require low saps oil. Its 10-40 of some description but thats as far as i can remember.

Hi there, if your mechanic has determined the egr to be leaking using a coolant pressure tester where it has put pressure on the system to see for leaks then perhaps thats where it is coming from. However it could be from pipes, thermostat area, water pump or the radiator. The EGR cooling could be in theory bypassed on a 2.0 just disconnect the two coolant pipes and replace it. However the EGR on the 2.0 i think from memory is stainless steel so unlikely to develop a leak this way.

@@peugeotCitroen2CV hello!thanks for the answer first! The mechanic said that either it was the egr,or the head gasket,and since both repairs costed too much the car was not worth the try.but i dont think he did a thorough check. Im happy with the car and for me it would a bit sad to have to get a new one,and for now it leaks very little so i can drive around 150km before i see the red lamp. What would you recommend?for sure it doesnt seem like there is any clear leaking anywhere,so it might be one of the things you mentioned.but also not white smokes,not higher fuel use,any power lose in the motor or any other sign apart from the level going down a bit. Thanks again for the help!

Should you see where the leaking comes from with a pressure test?thanks a lot

@@joshpatat4763 Buy yourself a coolant pressure test kit, ensure it has the cap for peugeot in it. When it pressurises the system you can go round and see if there is any visible coolant leaks. If there is oil in the water, it could be the engine oil cooler. Do not always suspect the head gasket although its not impossible. Water pump gasket, thermostat housing, hoses, radiator all other places where it could be leaking from.

@@joshpatat4763 yes i would recommend doing that

Clean the maf sensor with the maf spray. It will better read the airflow details. It is located after air filter housing, easy to take it off and clean, but dont touch it, can destroy it ! Also it is clever to disable the Egr valve, but only by software, someone who knows ( chiptunning workshop). Not recommended with blank plate, because it will turn on the engine light.

Hesitant, have you tried driving it with the MAF sensor disconnected? I don't think the HDI has a MAP sensor, especially not the 90 models. The EGR if its giving issues the car might smoke more and be down on power. Its worth just disconnecting the vacuum pipe going to the EGR and putting a bolt in it to blank it, then a plastic cap over the electrovalve to stop a vacuum leak. It will save trying to fit a blanking plate. Any other issues have a look on 406oc.co.uk which is the best place to go if you want a quicker response.

There are oil suction tools that can remove the oil from the dipstick but i usually just remove the sump plug as they should be designed to let all the oil flow out anyway (the 1.6 HDi DV6 engine i believe has the sump plug in a bad place and taking the sump off is the only way to guarantee that the old oil has been removed) but on the other engines just take off the sump plug and give it plenty of time to drain out. With your petrol engine the old oil shouldn't be too contaminated, and what little remains of the old oil won't be enough to worry about, if your oil hasn't been changed in a while and its a bit sludgy try one of them engine oil flushes.

Hi, I found out where the filter is. It is just above the motor. I coudn't believe it was there. LOL. I just changed it. I changed the brake rotor as well. I painted with a caliper paint. It is really beautiful. The old one is rusted but still in good condition. I will clean it vinager and then i will paint it. Without your videos I will never make it. Thanks a lot. Do you have whatsup so I can send photos to you.

+Moruf Bankole Normally on Pugs it is accompanied with some other warning, low oil pressure, high coolant temperature etc. Can you see any other warnings or oddities about the instrument cluster?

my timing belt cut and it has damage d engine,i need engine now how much is it 406 prestige

+Moruf Bankole What engine is it you have, prestige i am guessing is a trim level rather than engine. Ive bought full 406 HDi's with good engines for about £150 in the past so the 2.0 HDi is cheap as chips, the 1.9 XUD is still reasonably cheap. The petrol engines are more scarce but i wouldnt pay more than £300 for one.

Tubo intercoler 406 hdi 110cv

@@abdelkaderbelhadje330 Yes the 110 has the intercooler. Turbo all versions of 406 diesel had a turbo. The 405 was available without one but performance was a bit leisurely.

It is what the instructions recommend, although it would be better remove the air intake ducting and spray it in behind the MAF sensor.

@@peugeotCitroen2CV recommends to spray egr cleaner when you change the air filter? Or i misunderstand it

@@rccarslover7143 Its easy to do it when the air filter is out

@@peugeotCitroen2CV ok but is not for when you replace the air filter🤣 i was confused

Wynns EGR cleaner, a note though, remove the MAF sensor and spray it behind the maf sensor so the spray does not come into contact with the sensor.

It cleans the EGR valve (exhaust gas recirculation) the best description i can give is that its a valve which puts a certain amount of the exhaust gasses back through the engine and the end result of doing this is reduced nitrogen oxide (or dioxide I'm not good at chemistry) emissions. Although the sooty exhaust gas can clog up the egr valve and inlet pipes using the spray is supposed to solve problems with it being clogged up but i have used it here as preventative maintenance. Its possible to blank off the EGR valve some people think the car is more responsive but it depends on the car, had my cars EGR blanked off for a while but it didn't feel any difference and when the winter came i noticed the car took longer for the cabin heater to warm up so the blanking plate was removed.

So what kind of spray that you used? I have seen valve cleaner here in my country, but never see the EGR cleaner spray. I had 307 hdi, the previous owner blocked permanently the EGR hose (or maybe valve). So technically none of gas recirculated to the combustion. Is it what you mean blank off? I wonder if you could give us a video about doing de carbonation (carbon cleaning) job, very appreciate that.
