SOURCE: glowplug light comes on and goes off quikly, engine hard to start. Changed all 4 glow plugs and coolant sensor. Light stays on for a good 10 seconds when water temp. sensor is unpluged.

The glow plugs work in direct relation to the engine block temp. The relay for the glow plugs is obviously reading the wrong temp, that's why they turn back off. It's most likely that the temp sensor is bad, but trace the wires back and make sure there are no breaks in the insulation and they are well connected at the plug-ins. I have seen a lot of wires at the connector look good but fall off as soon as you touch them.

If the temp sensor is the same on for your your dash, then borrow a heat sensing gun and double check it against the guage. I have seen them read wrong by as much as up to 20 degrees. If the sensor reads rught and feeds both the guage and the glow plugs, then the problem would be either the wire harness or the glow plug relay. Hope this helps.

SOURCE: Why after putting oil in does depollution light comes on

Hello
The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPEDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

I've got a citroen Dispatch 1.6 diesel 07 plate the engine management light has come on and it saying depollution system faulty how can I fix this


I am guessing but it could be the particulate filter is sufficiently blocked to cause exhaust back pressure to become excessive.

If this is the case the car will need the solvent reservoir topping up and diagnostic equipment using to initiate a cleaning cycle.

Depollution system faulty the engine is dead car want go


Is there any fault indication on the dash where the radio display is.
Anti pollution is basically citroens way of saying emissions system so it could be as simple as a loose emissions pipe but from what you say and the car does not run it could be your catalytic converter (part of the exhaust system) has failed causing the engine management system to cut in and protect the engine.
If there is no fault apart from anti pollution showing in the radio display find someone with a diagnostic machine to give you a better idea of the fault. Hope this helps a bit.

Citroen C8 depollution system faulty


These motors and some other models with the same system always give problems .Havent done one myself as yet but other mechanics have that i talk too and if this is a diesel which has this system then you remove the particle filter on the exhaust system and make a rear box to fit type job and the sensor you disconnect and solder a resistor of around the 10.000 ohm mark across the sesnor wires to make the computer think all is well .Depends on the year though as to weither this will work satisfactory as a 53 plate sounds misteriously like some sort of secret code to me .Just noticed it says petrol 16v Hmm have to think again here as no idea with this one only ever see a diesel variant but if the cap fits so to speak have a look to see if has got a filtering out exhaust system if not then sell it quick and buy a ford or a VW

My 407hdi has 165000km on the odometer and gave me a message ''depollution system failure'' after starting and only idling at 800rpm before the engine cutting out. What does this mean and how can this be...


depollution system means emmision control unit which means lambda sensor + computer and catalytic convertor...
have the lambda sensor/oxygen sensor replaced.
