Maybe dribbling injectors

I was working in Saudi in 2000, and one of the locals told me a story about his neighbour's car. I think it was a BMW, bought from a dealer.
One day it would not start at the neighbour's house, dealer towed it to the gagrage, car was OK.
Next day the same thing happened. Apparently this went on day after day for ages. Eventually the neighbour was told that another neighbour was jealous and had cast a spell on the car. They got their local Imam to come and bless the car, and it was OK after that.
Honestly I'm not making it up, but obviously I was not there when it all happened.
Very interesting, but no use.

BX XU BOTTOM PULLEY
Dear Tim.
Had a thunk Tim, could be modified or race camshafts. they look the
same to the naked eye.
Another thunk was if some prevoius owner had had a cambelt on
them, they may have sourced a re-con head, from a slightly different
model year perhaps.

I know the history on the car Vince, the cam shaft hasnt been modified, thanks for the thought though.bx petrol auto saloon wrote:Dear Tim.

I think you're barking up the wrong tree Tim. You need to take the car to someone who knows XU engines to identify the symptoms and diagnose it. You can bring it to me if you like, but I'm a fair distance from you!
FWIW, all the earlier XU 8v's had shimmed tappets, not hydraulic. Not sure if yours is the same or whether they upgraded to hydraulic before they phased the 8v out entirely.

I may be kitch, but we have exhausted pretty much every other avenue, Jim Eastment of Xantia fame suggested the pulley, its worth a try, the cars in bits as a non runner at the moment so its an ideal time to at least try it.

Tim, i'm no expert on these matters, however, you've listed quite a few parts that have been replaced. Were they checked to make sure that they weren't faulty also? As an example, you might have replaced the ECU, was it the correct one & was it brand new or 2nd hand & was it tested? You might have already replaced a faulty part with another without knowing it?
I personally wouldn't spend another penny on the xantia, until you get it lexia'd & have a xantia expert thoroughly go over your car to find the issue(s). I know the car has sentimental value to you, but no point in getting despondant, afterall you've spent probably twice what the car is worth & its still in bits. Keep the faith a bit longer mate, but i don't think advice on the forum albeit well meaning will solve things, it needs to be plugged in & physically looked at by someone in the know. All the best & let us know how you get on.

The ecu was off the same age of car, and the part numbers were checked to ensure it was correct and the right engine code, it made no difference Everything else fitted was brand new.
It has been Lexia'd by sir Jim of Xantis, and there was no problems listed excpet that it couldnt find the lambda probe, which was replaced, Lexia'd again and a clean bill of health shown although it was now lumpy and sluggish were as before it pulled cleanly but very juicy.
I do appreciate everyone's input but we have tried every other avenue and keep covering old ground so if somoene DOES have a pulley then please let me know, ive got to give it a try. If that doesnt cure it then its going on a trailer down south to a man who insists he can mend it!.

This must be driving you round the twist, i don't suppose that the ecu was actually checked to make sure that it wasn't carrying the same potential fault if it is inface a duff ecu? Do these 1.8 16v have this common emissions issue & lumpy running?
What was the reasoning behind the replacement pulley making the engine work smoothly? Even if that fixed that particular element, surely that wouldn't affect the emmissions that much?
Don't suppose you've checked the replacement lambda probe, perhaps that's gone wrong as well?
Sending it down South might be the best bet if you feel you've tried everything else. Without sounding funny, what about just buying a replacement engine if all else fails & even down South doesn't work out?

So a bit more information now - am I right in thinking that it ran well but used too much fuel so the first lambda sensor was replaced after the diagnostic check showed no lambda reading. That all sounds as you would expect, as if the ECU doesn't see a lambda reading it is likely to revert to a safe (rich) fuel map.
And now it is seeing a lambda reading but lumpy and sluggish? Is the fuel consumption the same? Are the emissions the same?
Do you know whether you can read out live data from the lambda sensor via the OBD socket? Failing that a fast acting voltmeter or an oscilloscope might be needed to see whether it is switching correctly.
