Focus TDCi metallic rattle ...
Discussion
maybe nothing but then again could be DMF/starter motor
starting from cold i get a metallic rattle which lasts about 5 secs, this morning the rattle was louder then normal and its its first time i heard it for since last week.
I have had the aux belt and tensioner replaced, could it be the tensioner not working properly or do i have a mnore serious issue with the starter motor/DMF?
please help!

Hmm...my car does this ocassionally. I dont know what it is, but it hasnt got any worse over the last 8 months or so.
If it happened more often I would start to worry. how frequent is yours doing it?
well that makes me feel alittle better! the rattle occurs probably once a week, but sometimes i get it couple of days in a row and only in the morning when the car is cold. If it happened more often I would start to worry. how frequent is yours doing it?
have you had the aux belt and tensioner replaced?

You'll start getting whirring/grinding noises off the starter if it's the DMF, so if you havent got those I wouldnt worry just yet
I'm sure Ford said to me idle pulley for what I described to them. Whether it's a figment of their imagination is something altogether different though
thanks, if my car makes it out for another couple of months that would be perfect.I'm sure Ford said to me idle pulley for what I described to them. Whether it's a figment of their imagination is something altogether different though

Ive had tensioners (idlers etc) go on cars before. The symptoms are not far off but definately not the same, although that metallic noise does sound a bit like a dry bearing or something (metal hitting metal). A momentary blip of the throttle has never cured it on other cars. Its always taken several minutes of running for the noise to slowly dissappear.

yes, it only happens when its a cold morning and the car has been sat overnight. Ive also had it a few days in a row, but not at all since before xmas.

rattle today or yesterday. Ive had tensioners (idlers etc) go on cars before.

your description is spot on, a metallic noise that sounds like a dry bearing.
if doesn't get any worse then i can kepe the car for another month or so!
Hi
Best way to test the DMF is when its rattling,put it in 1st with hand brake on,and lift clutch slightly to allow it to drag,if rattle stops quite probably DMS.
Ford changed the DMS in 04,but only changed it in production and those that failed under warranty.
When it gets really bad it can effect starting.
Mine rattles like crazy,but as I do long journeys I've not yet changed it.

cheers, I'll give that a go when it makes the rattle next. my focus is a late 2004 model year (54 plate). i would assume it has the revised DMF.Best way to test the DMF is when its rattling,put it in 1st with hand brake on,and lift clutch slightly to allow it to drag,if rattle stops quite probably DMS.

i haven't had the metallic rattle for 4 weeks.. completely disappeared! but i have another problem a flat spot at 1900-2100rpm in 5th gear, doesn't always occur though and sometimes the engines drops power (like the turbo isn't isn't blowing hard enough) between 3000-3500rpm in second gear, then suddenly regains full power.

do you give the car a bit of a thrashing after its had the ecu updated? if not you should, from almost a standing start through the entire rev range for as many gears as possible, with the foot to the deck. The ecu is one of these adaptive jobbies and it takes time for it to figure everything out again.
I find it takes my car around 150 miles or so to fully recover from a reset (after disconnecting the battery) or flash update. Until then, it feels pretty flat and unresponsive, although it does steadily improve from the outset. Driving it harder than normal and taking it through the gears definately helps the process quite a lot though.

i pretty much drive the car hard can't remember if i gave the car a good seeing to on its last ECU update.
