So the PUMA goes back to the garage again tomorrow

Yes, it happens a few minutes after starting. It's a driving-along thing, not necessarily a start-up thing. The usual pattern is as follows:

- Start the car normally, nothing strange.
- Idle in the car port for only about 15-20 sec or so whilst I sort myself out.
- Idle down the driveway - nothing strange.
- Drive off down the street - engine coasting downhill - nothing strange, all smooth.
- Accelerate gently from the bottom of the street, drive without putting much load on the engine for perhaps 400-500m and few turns.
- Then, usually between gear changes, engine revs/rattles of its own accord.
(this morning happened between 2nd & 3rd, then again between 3rd & 4th gears)
- Drives normally from then on.

On the odd occasion when the rattle has occurred whilst in-gear there has been a noticeable loss of power.

In 18 months I have only had the engine light come on once. So far Land Rover's attempts to fix this have included replacing the fuel pressure valve and replacing the EGR.

solmanic its exactly the same as ours.....

Would just like to say that this morning was the coldest morning we have had yet....ice on the windscreens..

And the defender went into limp mode

Dullbird, sounds like your Defender's ongoing problems are ... indefensible. I would look into lemon laws.

I would like to extend that comment to most new 4WDs currently in the saleyards no matter what the make. They want to go into limp mode for the slightest possible reason.

A big let down to genuine off-road enthusiasts.

As far as I know, Australia does not have any "Lemon Laws". Manufacturers are simply obliged to keep fixing problems under warranty as many times as it takes and the only way to get any compensation for lost time & productivity caused by repeatedly having your vehicle off the road is to sue.

Is this what yours is doing?

If it's only rattling while the oil light is on I would think that's quite normal.

Help

I'm struggling with 14 pages and no real facts here.

I had a very brief episode of the chatters a few days ago...cold morning 200 m from home loss of power but no engine light. Mind you I am not losing sleep over it. A rare glitch is just that.

This has happened once before but with engine light and a replaced sensor.

My retorical question is "what is happening?"

What makes the chattering noise?

If the fuel pressure sensor is registering a fault is it because there is too much pressure or too little?

or

Is replacing a sensor like shooting the messenger?

We are dealing with a bit of machinery hereso there must be a cause for the effect. I see no forensic or engineering analysis.

I'm sorry Mahn but last time you had the problem or similar problem....you had a sensor changed you said all was fixed!

So is this the same problem you are having or now a different problem which seems to now be related to what we are all having.

A rare glitch :lol2: I wish a few of us could call it that.

You wont always get the engine light with the problem we are having mahn we have only had the engine light 3 times and two of those times we went into limp mode. (baring in mind we have had the problem for well over a year now)

The sooner people start to tell there dealers and keep on at there dealers about this problem the quicker the fix might get here...there is a software update coming for this fix apparently july.....I only wish it had come last year but with only myself complaining about it they were not going to rush about it for one person.

I'm not quite sure how to take what you mean in regards to you have seen no real facts in these 14 pages.

But I will answer as this if we could answer your questions in regards to fuel pressure and sensors then we probably wouldn't have a problem as it would of been fixed a long time ago....

They didn't know what was causing it hence the no facts.

I would idle it for longer,a couple of minutes and get some heat into it before I drove off.If there was ice on the windscreen give it more time. Pat

Well I have been onto my dealer about my rattle since a few months after buying the thing. In that time they have never denied that the problem exists, even though they haven't been able to replicate it themselves. They have had fault codes and done the two supposed repairs (fuel pressure valve & EGR) but I am keeping at them about the fact that the problem persists.

Its a tough one since, for me at least, it's not the sort of problem that makes my motoring any less enjoyable. Just the nagging knowledge that something isn't, and never has been totally right with the engine from new.

My plan now is to email and fax the dealer every single time it happens. Even if they can't make it happen when it's at the dealership, they can't really dispute a constant and detailed stream of feedback - all in writing - all with dates, times and conditions. No-one could claim that I was making it up and at least my service manager believes me and assures me that they will keep on it.

But Mahn, you are right. It doesn't make sense that a problem such as this, that at least four people on this forum are experiencing, has not been sorted out by Land Rover. Maybe we should all draft detailed letters to Land Rover (and I mean extremely detailed) and pass them around amongst ourselves so we all can verify how similar they are, then simultaneously email them to customer care. If they get four detailed complaints all at once, from different parts of the country, they might just realise that there is a design problem here that needs to be addressed at a factory level, not just having individual dealerships stabbing in the dark.

...that is if the supposed software fix that DB/MM have been told about doesn't sort it out.

Whilst that is good advice, this is a modern vehicle that was cold weather tested in Norway... It should be able to handle a quick cold morning start up in Sydney!
