Hi!

My MW failed its MOT this morning on headlight allignment. I have the factory xenon headlights which have an automatic sensor, so I'm not sure how to adjust the alignment. Ive had a look at the back of the headlights, and there appears to be two white stalks. Are these anything to do with the allignment? If so, anyone know which stalk does what?

Thanks in advance!

Owen.

Check the linkage underneath the car which is used to determine the body angle. Mine had sheared and I only noticed it by chance when I had my head under there once. If it is flopping about the headlights may have gone to full up or down deflection. If I remember rightly it was somewhere inboard of front right wheel (but it was a while ago).

Does it look like a miniature anti roll link?

Owen

Yes, and I think it's connected at one end to a variable resistor.

Brilliant! I found that the other month. It not connected to anything, I had no idea what It was. Thats probably the problem then.

There are two automatic adjusters for the original Xenon HID headlamps. One is on the rear axle as in the picture below and there's a similar one on the right hand front wishbone. The zero position of the headlamp beams should be set with the Fiat Examiner tool. I'm currently pestering Yani to add it to his FES software.

When any fault is detected with the automatic system, the headlamp ECU should point the headlamp beams to their lowest position.

Here's also a diagram of the manual adjusters fitted to the back of the headlamps.

That couldn't be more helpful!

I had my Xenon lights point down and stayed down after the F*at Garage replaced my rear bushes. they will not put right:bang:so was FES software ever done, if not what is the best way to sort?

As it occurred after replacing the bushes, it's likely that the garage has left the link rod disconnected (as shown in my picture in post 6 above) or worse, they didn't realise the rod needs to be disconnected before lowering the axle, and have broken the plastic arm on the sensor. I made the same mistake, the first time I lowered the back of my rear axle to replace the springs. Fortunately, I had the broken parts and melded them back together with a soldering iron.

You can now set the zero position of the sensors with FES (now MES). You will need to make sure both sensors are fitted correctly before doing it. Setting the zero position doesn't adjust the headlamps though. The sensors work by sending a voltage of between 0 and 5 volts (depending on loading of the car) to the master ECU in the left headlamp. Setting the zero position with MES tells the ECU that the current voltage is the level position voltage (probably 2.5 volts). You will still need to adjust the reflectors with the 2 white, plastic screws on the back of each headlamp housing.

Some good points, will have to look now it's got me thinking. Is a link available or subject explaining the use of the software and with what and how? Me thinks others would like to sort but all in all a very good explanation.

Davren you're one very knowledgeable chap. You got the same knowledge with the new Bravo? If so, I'll come looking for you when I get a problem. Lol.

Ya daft bugger. Lol, I know you're equally as clever, don't be feeling left out now. Lol.

Stilo Xenon Headlight

Does anyone know if you can fit these factory Multi Wagon Xenon's on a Stilo Hatchback?
I don't want to use a conversion kit and blind everyone.

Not legally without fitted the rear axle and sensors, front suspension sensor, all associated wiring and ECU(s) and front bumper with the headlamp washers.

Not worth the agro IMO, far easier to fit uprated headlight bulbs in the OEM reflector units, which are very good units in comparison to some cars from experience.

Hi Davren,

Sorry to hi-jack this thread, but I thought it would be best to post my question here rather than starting a new thread.

Could you tell me if/where you can get that ball jointed link rod for the rear headlight level sensor easily and cheaply?

My local fiat dealer can order it in on Monday, but its £23.22. That seems pricey for just a small, curved drop-link lol or is that a reasonable price?

Only place you would get one is a Fiat dealer or a breakers, but as not many Stilos had HID headlamps, there's not many in the breakers.

There's was one on eBay here (can tell by the headlamp washers) : http://www.ebay.co.uk/itm/131087751378?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2648 It's ended now but you could send a message to ask if they've still got it.

What's wrong with yours?

EDIT: Just found another one here: http://www.ebay.co.uk/itm/fiat-stilo-1-8-breaking-for-parts-/111303339843?pt=Automobiles_UK&hash=item19ea322f43

Search eBay for " Stilo breaking " then look at the pictures to find ones with headlamp washers. Most breakers wouldn't know that means they have HID headlamps.

What price would seem reasonable then

I don't see any issue with that price for an item which isn't mass produced and will have been taking up space on a shelf probably for half a decade.

Many thanks for the links Davren.

Well nothing is wrong with mine right now, but just the other day it was absolutely rusted solid that it ripped the whole sensor bracket off it's pop rivets. With some hammering on the back of the ball joint and working it with wd-40, I got the ball joint free and bolted the bracket back to the body. Then while out driving the next day, one of my rear springs snapped so now I need to undo this link rod to fit the new springs as you know (I'd rather not disturb the fix I did on the main sensor bracket) and because its so rusted I'm pretty sure the rod isn't going to be re-usable assuming I can get it off intact in the first place.

The only other option I thought of was to buy 2 ball & socket joints on ebay and bend a length of threaded rod to the right shape, but it doesn't work out much cheaper than Fiats price for the part and its more work. I may well go this route for the front sensor link rod as it doesn't need bending and Fiat quoted me £40 odd for the front one, so it would work out cheaper and worth while for that one.

I don't know, that's why I asked. If it's a good price, then that's fine.

I just thought I'd check on here with the people in the know as there may have been other options such as an aftermarket version that I just hadn't been able to find or like my DIY solution above. I was just looking for an opinion and advice on possible alternative solutions and now I have some, thank you.
