well aren't you lucky.....That you have such a bomb proof car!

Hey DB,

What's the fequency of these issues in the UK or mainland Europe? Bear in mind it is a lot colder there for a lot longer, would you expect there to be far more cases of this? Is this the case, or does Aus suffer more cases?

Pete I'am hearing of cases in the UK but not a lot as of yet same here though there wasn't any case's other than myself up until about a week and a half ago (maybe apart from solmanic but at the time we weren't sure we had the same thing)..And I have had the problem for over a year!

Thats one thing I said to Ian that I would of expected to see more in the UK.....because of the temperature.

Who knows there could be variables....Fuel/antifreeze...temprature during the day probably being double what it is in the uk before tumbling at night.
Could even be down to mechanical sympathy some people may have it but may not know

There could potentially be so many reason's why not....The same as Why was the PUMA released over there for a year and then have so many problems when it comes here? why did it taken them a year to find the water in the fuel and why a number of cases here and a few mentioned in the uk when they get more avaerage rainfall over a period of time.

I can't answer that question but I have people working on it..As talking to a guy in the Uk, Landrover UK appear to be well aware of the problem! So there must of been a fair few cases for them to be bothered about it. Might just be the case that we haven't heard of many.

I'm going to talk to the dealer and find out if they have heard anything..

Well here is a quick summary of my engine rattle:

- Rattle same as DB's and others' descriptions.
- Occurs within 1-2km (5 min) from starting, worse in cold weather.
- Started happening within three weeks of taking delivery of the car (Jan 2008).
- For first six months the rattle occurred increasing in frequency to about one in every three mornings.
- At six months it started getting quite bad culminating in an engine warning light coming on (June 2008).
- Reported to dealer, fuel pressure valve & fuel common rail changed.
- Over the next two months (colder weather) the rattle persisted, same frequency, sometimes quite badly but not enough to trigger any warning lights.
- Following first service the rattle was less frequent, but still occurred perhaps once a fortnight.
- Notified LR customer service so it was on record as having been reported more than once and not resolved (Oct 2008).
- Following a long trip in September 2008 I drained a LOT of water out of the filter/separator and informed the dealer.
- Second service Feb 2009 - dealer informed me that they had found a fault code logged that probably related to the rattle - replaced the EGR March 2009.

The rattle is much less frequent, but has occurred at least three times since the EGR was replaced in March. Warmer weather and now different morning routine means it is hard to say whether the rattle is as bad as before.

The vehicle is kept in a car port, and was prior to moving, so the general environment hasn't changed, just the morning driving routine. Like DB, my dealer had the car for three days last July and was not able to replicate the problem, even though it was occurring much more often. I also suspect they had the vehicle stored inside or were not starting it when it was cold enough to cause the rattle.

My dilemma now is this, the rattle is not happening often enough for me to be confident that the dealer could ever replicate it in the workshop. Also, if I could be sure that it wasn't going to cause any long term damage to the engine, I could live with it.

Maybe - but I was not trying to be smug - just letting you know my situation in regard to this issue in an attempt to help. Perhaps warming the vehicle up for at least 5 minutes before driving off prevents this problem.

BTW that's not necessarily a good idea. You have a look in your manual and I'd be surprised if it doesn't advise you start and then drive off gently immediately. Idling for that long wastes fuel and can cause other problems. I'm sure I've heard of bore glazing and oil contamination before - help?

makes no difference!......

He has tried that in the past.
And I have personally waited in the car for it to warm up a bit (not that 5mins gets much heat into the engine at tick over) and driven very slowly to see if I can avoid it...but no it still did it to me, I did it to see if it was the way Ian was driving. I think you either have this issue or you don't or something a long the way helps create it. I'm not sure.

So what happens when you're sitting in traffic - or on a club drive waiting in a convoy line? etc etc - there are many times when the vehicle is going to have the engine running for at least 5 minutes without driving anywhere. What is the different with these situations and at startup?

I've always started vehicles like this and I haven't had any issues - length of wait before driving off depends on how cold it is. The amount of fuel used at idle is negligible - I never get worse that 10l per 100km at any rate so it obviously isn't affecting my consumption in any noticeable way.

But I take the message from dullbird that warming up the vehicle makes no difference in the case of this issue. I, and I'm sure I say this on behalf of everyone here, we all hope your problem is resolved to your satisfaction and quickly.
