The fault code is the same with the new feed?
Thanks for reply sorted mine out it had reverted itself back to manual mode in setting switched it back to auto in the diagnostic and all lights came back on dash and it's be sorted for the last few months if any one wants a brand new x y z switch I have a brand new Oem one I never used will sell it for £190 and thanks for infoHi all. i am yet another to have to this issue. I have done lots of reading on this, and theres loads of forums threads out there and mostly everyone says the same information.
I did all the recommended checks regarding battery voltage, strong connections on the leads, earth straps (i even added and additional engine to chassis earth lead to make sure) and then changed the XY switch for a brand new one. But nothing fixed it, until i went to my friendly local main dealer, where i got the key piece of information.
"9/10 its transmission wiring loom that has a broken wire, near where it fixes with the P clip".
Sure enough, on removing the loom i found a broken wiring on one of the T junctions. Only one wire was broken, and a few others had some slight chaffing. Soldered up the break and now even is back to normal.
very happy to finally have solved this issue
I will add some pics asap.
had this issue today and a quick search led me to this thread. saw this post and gave it a try - it worked!Had this problem with mine....was told by a friend if the battery is giving out a good voltage, it could be the XYZ switch sticking. He told me to hold the auto gear stick button in and vigorously move it forwards and backwards a number of times. This sorted it and its been fine ever since
thats the next thing i will be checking. it doesn't seem to be running as smoothly as it should. nothing anyone else might notice but you know your own car. got a couple of unexpected days off so i'll be having a look.A friend had the M&S lights coming on intermittently? Checked battery voltage, but eventually found oil in the main ECU plugs. After cleaning and drying thoroughly no more troubles.
i have actually done that fairly recently though i might give it another clean. i know my maf sensor is dead, (no signal on neilly's nanocom) but it was running ok on default. it just seems very slightly 'rougher' than it used to be with a kind of 'rumble' at around 2000rpm. my engine mounts have seen better days so that probably doesn't help.If you're "going in" can I suggest you do something else? Check the MAP sensor on the inlet manifold. It's not at all unknown for these to be so caked up with black clag that they don't work correctly. Clean off with aerosol brake & clutch cleaner. Takes 2 to 3 mins but deffo helps with the running.

well... i did swap it for my old one which i cleaned up (very carefully!) but i dont know if that one was working as there was no noticeable difference. after having to splash out on a torque converter, i didnt have much left for a new maf sensor!You still have not fixed it? But I suppose at the time you had other things to sorry about....LOL.
Cheers
