Hi guys,
You've been a great source of info in the past. So here goes, 2001 HDi
Exec 100k miles recently serviced so all fluids topped (abd checked).
There's a strange clattering noise across all rev ranges and is more
noticable once into 4th and 5th gear. I know you get the bag of spanners
bit with the diesel but this sounds like a constant chattering noise like
a loose cover or something. Have checked the obvious and everything seems
to be in place but its still making this noise.

Is it to do with the time of year i.e cold air? The noise is pretty much
there all the time at the moment and doesn't go away when the cars warmed
up. The timing belt was changed about 4k miles ago would this have
anything to do with it?

TIA

It probably IS due to having had the timing belt changed. We experienced
exactly the same problem after having the belt changed on my wife's 406
HDi. According to our dealer (Castles, Leicester), the noise is coming
from the belt tensioner which is "hammering". Seems like it does not
like to be distrurbed. It works fine until the belt is changed and then
has a sulk.

In our case, the problem resolved itself within a couple of weeks.
Sounds like it's gone on longer with you. I'd refer it back to the
garage that did the belt change.

Probably unrelated to this episode (unless anybody knows differenetly),
the crankshaft pulley started to fall apart within a couple of weeks of
the belt change. That was a VERY expensive repair. Watch out.

Suggest you return the car ASAP to the garage that recently serviced
it and ask them. Even if someone was able to give you a reliable
suggestion of what may be wrong with your car, what would you do with
the information?
