Just wondering did you find what problem was with your lights only I've got front light malfunction error message. Thanks.




Yes spooky you should write here as I was just about to update this thread myself!  ;)


Having had the fault for 12mths now it got to a stage a few months back where (having changed jobs) I was spending far more of my time out in the evenings - hence spending more time with this error message.


From reading online there appears to be a few different flavors of this 'Front Headlight Malfunction' ranging from the more serious "my lights fail completely", to a more mundane "they still work fine, but" etc.


In my case (as above) the lights still work after the error is displayed, I simply experience a partial re-run of the auto setup 'sweep' (from left to right etc.) every couple of minutes whilst driving, certainly to the annoyance of other road users.


After having my car in at 3 different garages (including 2 Ford main dealers) for a combined total of around 16 days (faulty parking sensors (which I don't even have fitted) don't ask!  <_<) I have I think managed to now get a formal diagnosis.


At the last garage I visited I was able to spend some time with an engineer after explaining all the troubles i had previously. Anyhow, he kindly went through the fault diagnostics with me in the test station (for free which was good) and we narrowed it down to 3 possibilities in my case.


1. My passenger cornering lamp was only coming on intermittently (dodgy bulb)


2. Within the passenger foot well, underneath the glove box, there is a wiring board/fuse type unit (sorry not very technical with cars :P). We've noticed sometimes that when my wife's grandmother sits in the car (she uses a walking stick) the airbag sensor and other weird messages pop up from time to time.

Well the engineer showed and explained that on some editions either through manufacturing or over time, the carpet and board protecting this unit wears away/isn't fitted and so folks with long legs (me) or walking sticks/crutches etc. can sometimes knock this and loosen connections etc. 


3. Headlight leveling sensor


So for point one it was a fairly straight forward job of popping down my local Europarts store (very helpful chaps) and grabbing some new bulbs - think it came in at under £10 for a pair.

Took the lights out and replaced them both a fortnight ago and then refitted them. Sadly whilst this resolved the cornering lamp issue, I'm still left with he error & headlight problem.


Point 2 was simple - mine is still sealed and covered so fairly certain that it was only throwing up errors once some one actually hit it/stood on it etc With the headlight fault message coming on even if I'm driving the car on my own, then this wasn't likely the cause either.


Point 3 appears to be the problem in my case; After completing the above and booking it back in to the same garage, I've received a report that says the following:


- "Road test - confirm fault"

- "IDS Check"

- "Right hand headlamp swiveling feedback sensor fault"

- "Basic wiring checks complete at headlamp"

- "Requires new headlamp assembly"


Obviously this is output from what the computer says is a fault - I don't think there has been any human in-depth diagnosis of the actual head lamp itself, but I'm fairly accepting that this is probably the most likely cause given the error codes and what I actually witness when the error comes onto the dash.


What I'm less accepting of is the modern practice of making headlamps complete sealed units - £449 for one lamp!!  :angry:  I think I'll take my chances with the scrap man.


So that is where I am now.


Apologies for the lengthy feedback, but I wanted to just give you and others who may stumble across this in the future, some points to try before heading down the replacement route.


On a more annoying note - the late 07/early 08 titanium X models have halogen bulbs as opposed to the standard xenon of later models. So I've the extra complication of trying to make sure I find a drivers side - automatic leveling - halogen headlamp for cheap as chips as I'm currently laid off work too....The words needle & haystack come to mind...!


I hope this helps - even if it gives you some things to check off, that aren't the reason.


Good luck.

I can see how that abbreviation may get you in trouble... :P


Thank you very much for the pointers - If/when it ever stops raining>sleet>snow>raining here I'll get out on the drive and get the headlight unit out and do as you suggest.


Something which my wife spotted last night actually from coming back in the snow is that the drivers headlight unit seems to have some condensation on the inside - I'm in no way mechanically minded but I'm guessing water + electrics could also be a possible cause?
