Old Friend.
Looks like Ive bought a naill , its still failed tho MOT! New Lambda probe is fitted, but emissions are still too high, does fluctuate when u thrash it to a passable level but as soon as it ticks over it goes up and up!
Emission light comes and goes off again! Mechanics are now claiming could be a temperature sender/ catalytic conveter or even a headgasket or all of the above!
Noone local to work on it either! Anyone know someone in the burton area who works on citroens/peugeots please speak up!
If it was any other car I would get rid and get what I can for it!

If you mean Burton, Lincs, then I can recommend John Hannam in Lincoln. Mr Barnsley BXer should have his number as I recall he has taken a car to John before. Otherwise I have the contact number of one John Bradshaw, Xantia owner (amongst others) who is a fine mechanic who lives in Kenilworth - he works for Land Rover. I also know a keen Citroen enthusiast who lives in Hinckley, who does a lot of work on his own cars, mainly GS's, but he also has an XM - but might not know much about Xantias. They're all CCC members
Hope that helps!

It is all about doing a proper diagnosis. Your monkey has changed the lambda because the engine check light comes on. This is not the sole reason for the light coming on. The lambda is his first guess at £42.
Check all the connections to the various thermostats and temperature controlled resistors If one fails, the Lambda voltage will be wrong.
It would not cost so much to strip the plumbing off and wash it through, checking that all the pipes were sound and the clips tight, That the throttle body was well washed out, that the oil and filter were fresh, the injectors clean and that the air cleaner was new. Spin out the plugs and that will tell you a lot. A good thrash for ten miles and maybe the light goes out and stays out. Even if it doesn't, you have ruled out most of the likely problems. Swapping expensive components by guesswork ain't my idea of fault finding. Reading the lambda voltage and determining what is wrong with the mixture is the right way to do it.
The emissions were wrong. The sensor gave the "wrong" voltage; not because the sensor was duff but because that was what it was reading.

"Emission light comes and goes off again! Mechanics are now claiming could be a temperature sender/ catalytic conveter or even a headgasket or all of the above!"
Notice again how they're suggesting expensive faults... Imagine if they changed the cat and the headgasket and it still failed the test on emissions... I'm amazed they haven't stripped the carb yet.
I had a bad experience with a Cit specialist, whose first recourse when tracing the source of a misfire was to strip and clean the carb (GSA). It didn't cure the misfire of course. I found much later that one of the brand new spark-plugs they'd fitted was completely fouled with dirt, probably picked up from around the hole. The car had no misfire when I took it in to their garage - but it suddenly had one after I picked it up (after hours). After I cleaned that plug - magic - misfire gone!
I go with what Ken says. I always combine my MOT with a service and pre-MOT check-over, which usually involves oil and filters change etc.
