Thread: Ongoing Immobiliser Problems 130 Puma

I run the GAP diagnostic tool sold through BAS UK. Wasn't cheap to buy the license and ECU remap. As a diagnostic tool and live data tool it has saved my bacon in remote Oz a few times. I wouldn't travel remote without a means to fault find. Money well spent imo.

Tombie has described the remapping process. it really is simple as plugging in the bluetooth dongle into the OBD2 plug, launch app, turn on ignition and let the 2 talk to each other. While i don't change maps very often (almost never now it's set up), i've not had it fault out on me leaving it partially re-coded.

*Was the switch on the back of the key barrel changed? This is a common fault.
*As the TDCi (puma) 2.4 uses the same imobiliser as the previous model TD5, any repairer that has the tools to turn off the handshake on a TD5 can do a 2.4

*you really need to find a repairer that has a clue about Defenders...

You would have thought one of the biggest Land Rover dealerships and service workshops in Sydney would be bale to diagnose and rectify this. They have had it there for a month now and claim they test it daily but are unable to get it fault when there. I know I will pick it up and it will do it again.

This is driving me nuts.

No I wouldn't have thought that for a minute

Well after having the vehicle for a month they can't get the immobiliser fault to replicate. They have now decided to replace the immobiliser with a brand new one. This has to come from England so will be a week or two arriving. We will see if this is the issue - I doubt it but anyway worth a try.

Latest update - The tell me me they have been in touch with the technical department in England who have diagnosed the fault - they think. Apparently they say that when locking and unlocking the vehicle with the fob, the Australian set up as opposed to the European set up sends a signal to the ECU to make the blinkers flash and this is also supposed to tell the immobiliser to disengage. They say that there is a fault in this whereby the lights activating causes an issue and does not disable the immobiliser all the time?????? Go figure. They say they were able to get the vehicle to fault a number of times and once they reset the system the fault went away.

This would appear to be a cheaper solution for them as they now say there is no need to replace the immobiliser which would cost them around $3000. I pick it up tomorrow and they want me to monitor it and see if this fault does not happen again.

Here is hoping as I am planning to do another EDJIT Simpson adventure fairly remote next winter.

Well like Gomer Pyle once said, Surprise Surprise Surprise. First trip out the same immobiliser fault reoccurred, yet again 4 times. Back to the highly reputable Land Rover service team who will no doubt re-consult the Book of Armaments, the entrails of chickens and dusty fortune telling cards for the next installment of "We can work it out" - not.

I keep telling them - override or bypass the immobilizer, I don't want it, I don't need it but they won't do it.

The frustration level is now on full overload.

You could fix this by taking it somewhere else.
