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!

And now the good news.

I did lift the bonnet on your BX this afternoon, just to see whats under there :lol: it looks to me like there's loads of adjustment left on the clutch.

Yeah... I thought Burton, Lincs was a bit far from Leicester!

Just a thought, have you checked out the list of Cit specialists on the BXClub website? There are two or three in Warwick, and one in Stafford.

Kewl Ken but as youve got the clutch did u want to fit it anyway?

Work tried to adjust the clutch beforehand and didnt get anywhere, and as its the original and the cars done 170000 miles its maybe wise!

Yeah, I know, once I've had a good look at it we'll come to a decision.

Of course it failed on emissions. There is a new lambda sensor fitted. Why? because the engine check light comes on.

If you let monkeys do your mechanicing for you this is what you'll get.

So what do you suggest Tom? Am limited where I am, I dont trust garages I dont know, especially these fastfit outfits, so I prefer to have it done on site so I can keep a eye on them!

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.

I NEVER EVER take a car for an MOT test without first changing the oil and filter and air filter.

Then a good blast in 3rd or 4th gear to blow the crap out of the system. It's only common sense. An engine can only put out what it draws in.

"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... :roll: 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. :x 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.

I rang citroen, as a last resort, they have come accross the problems and said to put some fuel cleaner through (it is injection) and I am changing the oil anf filter, spark plugs and air filter as a matter of course. Have checked all the connections and all seem fine.

Try again!

Tim, have you tried Mark Lightfoot?

There is a citroen/pug specialist in Burton listed in the yellow pages i've got at my desk at work. See if its still listed in the latest one

Local mechanic has a scanner we can borrow next week so gonna put it on there

Our foreman thinks its the cat! as the emissions as is would pass a non cat equipped car!
