hey pat ours pulls hard to the left also perhaps this is also a common fault of a common rail diesel .......

Pat I dont deny other newer models have problems also.....but for it to be suggested that our "problems" are because we don't know common rail diesels I find to be honest a little insulting...

I some times feel the brand honour is just a little bit to much, to the point where I feel sometimes we are not even believed we have problems with our cars.......just because others have worked on them type of engines does not mean we don't have issues.

I'm afraid we DO have issues...not all but some. I wish sometimes people would just do us a favour and stop making it out that its our fault or our lack of knowledge and understanding of how common rails work as to why we have these issues.

It can sometimes get even more disheartening when you have troubles with the car and then feel you have to battle with your own fellow landy owners that we all come to for support just to prove we have issues because we are not believed. Makes those troubles we have just that little bit worse.

Oh and just so there is no confusion I'm not just talking about this thread but many many other where people have gone out of there way just to try and prove us wrong

so when I say our etc I'm meaning in a collective term not just me.

I did have water contamination but only in the fuelk tank and a little in the filter but not enough to carry through I hope.

The wind sound I did not notice while recording but must have been caused by the fan draught.

It makes no difference clutch in or out but I also have I think another broken clutch but that is heared driving in gear at low idle revs.

This engine idle noise is only sometimes evident and varies as to when it occurs other than it must be a little warm before it hapens. Never when cold.

The best way to describe it is a rrrrrrr pause rrrrrrrrr pause rrrrrrrrrr at idle and dissapears when you rev up even slightly above idle.

Maybe I just have to live with it. Was never there from new which makes me think "problem brewing"

No one is saying that haven't had your share of troubles but you are taking advice from dealers who I know for a fact tell BS to satisfy customers.All CM engines rattle,thats what they do and looking through other forums everyone is complaining about it but everyone has to get used to it.The biggest problem with dealers is they don't find the problem with vehicles they simply replace parts hopeing it fix's it.You fall into that area.

What advice is that then PAT?

as said above do they all go into limp home mode on a regular basis...????

I'm starting to think you only read what you want pat

Still i have always thought the puma sounded different.........I have also always thought this is what they sound like.

Still this is the first post I have seen complaining about what they sound like, so what other problems are you referring to that are common to moden day diesels? bad clutch? failing vacuum pumps? failing diffs? turbo heat shield bolts falling out water contamination due to poorly placed components, faulty EGR........These are some of the most common faults and things I hear people complain about I wouldn't say that these are all due to people not knowing what a common rail diesel sounds like.

No, I was only refering to the "rattle" I've heard mentioned on here a few times. I'm aware that they have their other issues. I'm sorry if I offended anyone, just trying to help by saying that CR diesels do sound different to old school diesels (and seem to change their note from time to time - or at least my work Ranger does). Hopefully there are many more good stories about the pumas out there - its just you don't hear many. (Like Falcon XR6's - I've got one and can't fault it, but they all have bad diffs and gearbox's full of water apparently!)

Sticking cooling jets will cause premature bore wear and cause an audible knock.

It's definately not a knock - but on advise from all here it seems to be ok for a commonrail. Thanks for putting my mind at rest.

I drive a D4D at work and I have a terible knocking when cold and on start up which lasts for about 8 minutes of driving.

Another thought that crossed my mind. Reading the water related posts in DB's thread regarding engine knock etc.

I was wondering if I may have slight water errosion on the injectors as detailed in an article on the CR's. My filter had a lot of silt and a little water before relocating the breather after a long wet trip on dirt roads. The article stated that if the filter was blocked the suction could draw up some of the water sitting in the bottom.

How do I convince LR to buy that theory and can injectors be removed and tested for this cheaply?
If LR were not interested could I get an independent diesel injector shop to at least remove one injector, test it and then I could take it and a report to LR to get them to change all if it proved to be leaking.

Long shot maybe???
