Don't think there was ever a recall in the UK, LR never admitted there was a problem. I'd be interested to hear of any evidence of a recall.

It affects all p38 that have to press there key fob to disable once opens early unlike laters that read key fob from ignition simple show me a thread with a key fob that don't register from 1999 onwards!!!

Would you like to re write that in some language that we can understand?

Unlock your car with the mechanical key in the door then try to start your car it will say engine disabled press key or enter eka code old type
If you unlock your car with the mechanical key and go to start your car it will new type passive ingnition coil simples that's why the old type struggle with Interference and the new type don't simples that's why you will never see a late diesel with keyfob problems unlike petrols that lose sync any shape or form
If you unlock your car with the mechanical key and go to start your car it will new type passive ingnition coil simples that's why the old type struggle with Interference and the new type don't simples that's why you will never see a late diesel with keyfob problems unlike petrols that lose sync any shape or form

Sorry passive ignition coil and RF interferance are not the same things, but of course you will not accept that so I will not be wasting my time.Unlock your car with the mechanical key in the door then try to start your car it will say engine disabled press key or enter eka code old type

I know the early one rely on the rf receiver to tell the becm
The later ones the coil in the ignition register the code that's the diffrance
I assume you are talking about key synchronising.??I know the early one rely on the rf receiver to tell the becm
The later ones the coil in the ignition register the code that's the diffrance
The early models, you had to unlock the door mechanically and press the Fob button....this told the BeCM to re-sync the fob/BeCM rolling codes....the signal was received by the RF Unit which sent it to the BeCM, the BeCM then told the RF Unit to tell the Fob the New Rolling Code sequence....
The Later models had a passive device in the Ignition coil which would sense sense the key was placed in the ignition, this would then trigger the RF unit to send the resync rolling code to the fob....
The resync is still done through the RF Receiver as all the coil in the ignition barrell is there for is to initiate the resync....it is purely passive....it has no transmit function....IIRC

Yes saint that's my point the later one work perfectly through the ignition where as the early ones relied on the press/ signal from the key fob and from that problems arise
but this function does not only work for sync it also triggers the rf to send that's why I have explains about opening with key if you had the early type you would have to press the button to start the late you don't becuase it reads the key in the ignition

Yes the earlier sync was a pain...but the way it works is exactly the same....the only difference is the coil tells the system initiate the sync instead of having to push buttons and unlock/lock the door mechanically is all.....the sync is still performed usign the RF unit...so if you have issues with the RF unit, it won't matter whether it is an early model or late....as the RF unit handles the sync codes not the passive coil!Yes saint that's my point the later one work perfectly through the ignition where as the early ones relied on the press/ signal from the key fob and from that problems arise

Yes but what people don't Realise is that the press of that key can get interrupted and that if it hadnt could be low battery ect you wouldn't of had the problems in the first place that's why the later one reads the key and you have no problems
So even if your rf hasn't been changed its not always the rf but the key why do think they changed it to passive
The Later ones don't read the key...the coil is passive....it just initiates the sync....you still need the RF unit to send/receive the rolling codes...all the coil does is initiate the sync by exciting the fob to send its sync code....Yes but what people don't Realise is that the press of that key can get interrupted and that if it hadnt could be low battery ect you wouldn't of had the problems in the first place that's why the later one reads the key and you have no problems

from RAVE:
So my reply stands, if you have issues with the RF receiver regardless of passive coil or not...you will still have issues with synchronising the keys....

That the key fob alone with buttons doesn't always do so IMO its more relyable therefore you don't have problems with the later ones
Unless your RF unit is causing problems then regardless of which sync method it is passive or button push...it still won't sync....
Yes duff buttons on the fob will not allow you to sync...but so will a duff RF unit.....as per my original reply and subsequent replies thereof....

On 1996 and later models (UK, Europe? and some other markets, but not North America or Australia), the system was "improved" by adding a so-called "passive immobilization" feature (enabled in North America and some other markets) that activates engine immobilization whenever the key is removed from the ignition, regardless of whether or not the vehicle is subsequently locked or the theft alarm armed. A "passive immobilization coil" was added around the barrel of the ignition switch to trigger a code from the (remote handset )when it is inserted in the ignition, enabling remobilization ok not sync but it does that as well....
Now I might be FRIGIN stupid but this next bit is about the remote not the FRIGIN rf if you press the button but you have Interference it won't work where as above the ignition isn't affected and will always make it friggin transmit !!!
In the UK, a different frequency (433 MHz) from that in the US (315 MHz) is used for remote locking and several owners have experienced trouble using the remote to lock or unlock the vehicle when parked in places where a lot of radio interference is present, such as at airports. Joe
The problem isn't the button on the fob, the problem is that the message it transmits isn't picked up by the receiver because of interference. The code that gets transmitted when you plop the key in the ignition isn't sent to the BeCM through the barrel, it is sent via radio waves. If your receiver is being bombarded by rogue signals you're not going to start.
My late 1999 (so late it was almost a 2000) has had problems with interference in the past. Most noticeable was when I parked near RAF Fylingdale.

You weren't on about the Passive Immobilisation system, you were talking about Key Fob Sync....
The Passive Coil Immobilisation system excites the Fob to send a code to the RF UNIT to tell the BeCM to remobilise the car - the key sync function is carried out at the same time to ensure the BeCM and the Fob rolling codes are always in sync hence why the later models where called 'Easy-Sync'....But if the RF Unit is blocked by interference - regardless of if it is a late or early model, with or without Passive Coil - if the RF Unit doesn't get the rolling code signal from the Fob it will not remobilise the car or resync the Fobs....
All the Passive Coil does is tell tthe Fob to send a code to the RF Unit to tell the BeCM to remobilise the car and to send back to the RF Unit a New Rolling Code to send back to the Fob....
The Coil is passive, it is just a magnetic field, it does not transmit nor receive anything...that is done through the RF Unit....all the Passive coil does is excite the receiver in the Fob which tells the Fob to talk with the RF Unit....nothing more nothing less...the Immboiliser and sync is all handled via the RF Unit and the BeCM not the Passive Coil.....
On the early models without the Coil, the BeCM and the Fob had awhole bunch of Rolling Codes stored in it.....each time you repss a button, the rolling code within the Fob changes....and the BeCM tells the Fob which new set of codes to use.....
If the Buttons are pressed repeatedly away from the car, or if the car is not responding to the Fob....each repeated press changes the Fobs rolling codes through the set it received....BUT the BeCM Rolling codes don't change and the Fob and BeCM go out of sync with eachother and have to be reset to eachother by going through the resync procedure....
The Later models did away with this mostly, as when you put the key in the ignition the key and BeCM will reset eachother s rolling code set, and as such was known as the Easy Sync system.....

What in saying is yes the rf tells the becm to tell the ECM everything is ok
Why do you think you get so many people saying my fob doesn't work it won't resync
The old system you had to press the button to either resync or unlock disable doors ect that message was getting lost Interfered with from the fob
I don't know how or why but now by putting it in the barrel it always disables and resync's that message don't get lost now from the fob unlike the early type that's my point

You do still get people without of sync keys on the later model.....because the RF Unit interference problem....
The reason you get more people complaining baout the earlier models is because the sync process is more complex.....
The reason you don't get many moaning about the later models is because once the cause of interference is gone it will sort itself out automatically....whereas on the earlier one, you have to do it yourself....
They are both just as prone to lose sync, and just as prone not to resync if the cause of the interference is still around......it is just once the intereference is gone the later models will resync themselves..the early one won't.......and thats my point!

Jesus you're thick. Put the key in the ignition on a car with the coil and watch the LED on the Friggin Fob Flash as it sends the code to the RF. Take aerial wire off on later cars and it doesn't always work, likewise if the receiver is picking up crap it doesn't work. All it does is replace a push of the FOB button. You can chuck the coil away and still resync by pressing a button.
The other reason later cars have less problem is because they have the MK2 receiver.

ok saint but I don't know of any late diesels that do its always the petrols yes
