You need an auto electrician to connect a pro grade scan tool computer and it will diagnose codes and communication errors that a cheap tool can't.

What is a 55 plate?

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.

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

folks out side UK have no clue what my51 plate
we use the VIN to learn what year it is. and engine,and what country sold to.
is dash heater blower dead? on even high? speed?
test 1 of 10 . or so.
test 2 does pcm scans show ect at 180 to 200f temp?
google 200f to C and get your answer.
test 2 do both fire wall hoses, to heater core feel super hot, hand flays off?
i not both the core is clogged
if all hoses water feel cool they are and thermostat bad or missing

I have a dispatch 52 plate with no working reverse lights, I THINK I need a new reverse light switch which is ment to be with the bulk of the engine but I cant for the life of me find it, any help would be great

Hi, i'm pretty sure that it's the warning light to tell you to drain the water trap on the bottom of the diesel filter.
Hope that helps Matt...
