Folks just ticked over 400 kms and the car really does drive nice. I notice I have a slight pause in power when accelerating in second if revs are a little low, this could be turbo lag? The more concerning issue was a rattle AFTER engine is shut off, I feel it's tied in with what feels like some slack with clutch and gear changes, if you let the clutch out a little fast it makes the change rough.

What would the rattle be on engine switch off?
I had completed a 100km trip when it did it, it may have dome it too on a gear change from 2nd to 3rd.

Thanks in advance

pc,,,,,,,i,ve just clocked 5oo k in mine ,,110wagon,,,,, has a few squeeks ,but no shutdown rattle,,,,,,,, have noticed rough gear engadgement on occasion,, i put it down to driver error ,,,,, drove proffessionally for tnt for over a decade and the box is good but requires positive selection in my opinion,,,,,, it does behave more like a truck/commercial g-box than a passenger car,and i figure this is a good thing ,,,,,, 1st gear is particularly low ,,this is superb for offroad ,,but demands once again positive selection of 2nd - 3rd and so on......one could assume the box may wear in a touch!!. i may be way off the mark here ,,because this is my 2nd l/r in 20 yrs but i know my g/boxs ,cheers

ps; i find the donk great it just lives at 2000rpm ,,any more appears a waste...short shift......less is more...


buy yourself a tube ,,sikaflex/silastic ,,,,,,and cure the floor of swiss cheese syndrome,,,,,,dust/water /mud.

I think the motor is very good as well, gear changes are clunky if I don't do the change the way it likes, you can't let the clutch out really quickly or it does it. The rattle on shutdown is the concern sounds like when you shake a nut or bolt in a empty Milo tin. Yes the motor works great at 2k I am impresses with the rig I just know there will be a few little teething issues cause that's defenders as a general rule

Does it sound like this?

YouTube- Strange Engine Noise

If so it's the EGR.

Hmmm - if is is 400 Kms, then it must be a Puma, so then it will be the EGR cycling.

It if is 400,000Kms, then who knows!!

Yeh may be similar from the drivers side sounds like a bolt spinning in a tin. It's only after motor just shuts off. If it is egr what does this part do and how long to fix it at the dealers?

It cycles 5 times to clear things out or something. This is by design, so dealer will not need to fix it. Lucky hey!

Agree with spudboy the noise is a "thack, thack, thack" it will be your EGR valve doing what LR call a "self clean" funny since they play up by getting jamed.??

The other noise you hear, could be typical drive line chatter most defenders do it either if the clutch is released bad or when fully loaded on a big hill and you punch the clutch in or stall it! It doesn't sounld good :o

thanks folks I think your right egr so how hard and how long to fix this ? Sounds like it's from the passenger side front part of motor when your sitting in the drivers seat. Is it safe to drive until you get it too a warranty repair place ?

no it wont stop it shoudl do it every time the car shuts down assuming it is the EGR cleaning itself

As for gear changes you can't come up quick on the defender...however if you have to baby the clutch which I have had to do many times it could be your clutch as my changes improved a lot when this was done..

i also found that a badly adjusted handbrake can also create this.....when My handbrake was recently done the changes where smooth quiet and faultless..then my handbrake played up again and it felt like a bag of **** to drive:D

The noise you describe does sound like the EGR valve cleaning operation. The EGR cleaning operation is a normal operation for the vehicle designed to clear carbon build up on the valve. It is not a problem and does not require repair as it is doing what it is meant to do. You are more likely to notice it in an enclosed area or when the radio is down in volume when you switch the vehicle off. If it does pack it in it will probably throw a fault code and produce a warning light.

The gear change "clunk" seems to be part of the Puma experience. Don't force the change but be positive and operate the clutch gradually and smoothly. The clutch "bite" point in mine tends to be at the 3/4 point of the travel. The technique will develop with a little use. I can get smooth positive gear changes every change and no "clunk". I don't have to drag the clutch to do it. I don't over-rev the engine. You will get used to it. I also tend to give the throttle a nudge in neutral on the down change which also helps produce a smooth shift. I drive it like a truck as it is more a truck than a car!

so the egr will always need a clean and therefore continue to make this noise so just ignore it seems to be the answer.

this forum is great.... I get the gear change right 3/4 of the time when I get it right it's the sweetest gear box I have used, it's a short throw and very slick I just can't get over how nice it goes on the highway compared to my 1999 cruiser ute. It also feels different in paddocks, it seems to negotiate drains and rough terrain in a more stable way than the cruiser used too as well. Right now it reeks of sloppy sheep **** as heaps if it was thrown up underneath yesterday

What is the engine and vehicle?? Was asked earlier.

From the discussion I am assuming a 130 with a Puma engine.

Please indicate engine etc that is being discussed in threads if it is not clear in avatars/signature blocks.

However if it makes as much noise as mine, it is faulty. Mine can be heard from inside the house over the stereo, it will also give the noise occasionally whilst driving. It has been like this since last September but I haven't been able to get back to the dealer yet. It's booked in for a couple of weeks time.

So if it is REALLY loud, get it looked at.

It's not that loud and controlled. I have just started garaging it and it's more noticeable in the garage which echoes a lot.

Do all Pumas do it and if fuel is old or lesser quality would that make the egr self clean more?

dose the noise go away with the clutch disengaged, if so its clutch rattle, and yours been a new car you will have the ungraded clutch ,

pumas do rattle on shutdown/ start up, it just the ford clutch:mad:

Do all Pumas do it and if fuel is old or lesser quality would that make the egr self clean more?

All Pumas should do the self cleaning cycle on shut down. From the manual:


OVERVIEW
The EGR (exhaust gas recirculation) system comprises:

EGR (exhaust gas recirculation) modulator


EGR (exhaust gas recirculation) cooler

Gas transfer pipe and mixer


The EGR (exhaust gas recirculation) cooler receives exhaust gas directly from the exhaust manifold, where it is cooled by a water matrix which is integrated into the overall engine cooling system.. Attached to the Cool side of the cooler is the EGR (exhaust gas recirculation) valve. This valve is motor driven – controlled by the ECM (engine control module) to provide varying amounts of EGR (exhaust gas recirculation) recirculation depending on the engine operation. At engine switch off the valve opens and closes several times to clear any deposits which may have accumulated during running.



The EGR (exhaust gas recirculation) pipe transports the cooled gas to the mixer where it is blended into to the incoming air stream. The ECM (engine control module) monitors the EGR (exhaust gas recirculation) system function and stores fault codes in the event of failure. The EGR (exhaust gas recirculation) valve can also be activated for testing using the Land Rover recommended diagnostic tool.

no I tried before in garage with car in neutral not touching clutch at all switched car off it did the little thack thack routine maybe 4 to 5 times. And it was not that loud just there.

i mean buy clutch disengaged is foot on clutch;),

the clutch is not spinning?

On my 2007 Defender Puma the EGR valve operation occurs after the engine has shut down. There is no rotation of the engine or clutch components at this point. Everything stops then the EGR valve cleaning operation starts with its 5 cycles.

Stig as above there is no rotation if clutch when it does it. I'm glad it's not anything to be concerned about at this stage.......all the sheep dung on it is a bigger concern lol

PC3, I think you me and Brid all seem to have new Puma's from the recent shipment. Did you collect yours in early June? I did.

As you will see from my other recent posts, I have some sort of transmission rattle issue. Let's keep discussion of trans that on that thread (http://www.aulro.com/afvb/90-110-130-defender-county/107434-puma-transfer-casefree-play.html) but let's compare notes with Brid.

But what I noticed on my first big drive in terms of the possible EGR issue exactly mirrors your feedback about "lag" at low revs. I described this as "hesitation" on one of my earlier threads.

I found that when accelerating in gear on a light throttle - it seems to only happen in these circumstances - it's like the engine is struggling for fuel or air.

I can make it happen easily going 2-3-4 with a light throttle, or also when accelerating from overrun in 5th or 6th. When I put my foot down a bit harder, it seems to "push through" the issue and go all smooth again.

When I described the sympotoms by phone to the dealer (Alto Sydney) they thought it "sounded like EGR". Mine is going in for a look in 2 weeks time. I will write more then, but as with the transmission or rattle issue, I suggest we compare notes as this sounds like a batch issue...

Gav, I exhibit some of the symptoms you speak of.......I am not whinging as I have gone in eyes wide open. I'm 1 hour away from either Geelong Melbourne docklands. Tomorrow it goes for bullbar lights etc. A few more kms I,ll get my list together and see if some things can be looked at. For me the 130 is the most practical car around, all in all it's brilliant just a couple of teething issues I think......should not be the case, but it's Defenders. I just need to work out if Geelong or Melbourne are more knowledgable with pumas.Shoot us a pm if you want my ph#

Pulling into our street last night after a 14 hour shift, wife sends a text needing something for young bloke from chemist. Nearest chemist at that time of day is 40 minutes away. No worries, an extra hour or so in my defender playing what's that noise makes me a happy man after a long day. Love it!
Gav, mines an 07, if you want to get together to compare rattles one day.

Thanks Pumice - that would be great. Here's my timetable:

- Dropped the Defender off with Daniel/Mulgo today for the rest of the fit-out (side step/sliders, wheel carrier, 12V power, 2 x batteries, sound proofing, DVD, cameras & stereo etc.) - will take 2 weeks
- Get it back in 2 weeks then straight off to Alto to diagnose/fix my issues - I plan on leaving it with them for up to a week if needed. Have sent them a detailed list by email and logged all conversations for future use as needed. Hopefully woin't come to that.
- CouplerTec anti-rust unit fitment scheduled for WED 7th
- Booked into Heasman Steering to custom tune the Bilsteins on 12th
- Hopefully back on the road by 15th so I can drive it back to Melbourne (I visit my office there every month) and get some more miles on it
- Hopefully camping mid July & catch up with you then or after that. I will post my camping dates up on the Upcoming Events as soon as I know in case anyone wants to meet up, compare noises and fit-outs and do a few tracks ;)
