Hello All,
I am having trouble wit the car due to immobilisation.


The problem started with a key problem. The key does not unlocked the car and alarm start to went off. And the car immobilised. Even the local licensed dealer/service can not solve the issue. I transfered the car to an old technician. What they told me is When they connected the car to the T4 diagnostic everything went normal and the car is starting and working very well. When they disconnect the car immobilising again and not starting.

He say we cannot program with T4 diagnostic because BCU is on the limit of programming. It cannot limit reprogramming again. So I have 3 main questions:

1. Does BCU has a limit of reprogramming/or reseting to remobilise the car? There could be a missunderstanding. I assume T4 is the original LR service machine and should do anything. Also I do not think if BCU has a limit for that. if there is, I need advise to how to reset it.
2. Is there any way to fix via T4 diagnostic tool?
3. In Turkey, NANOCOM is not sold and bringing is not very easy because of the Customs. Is there any other solutuons that can help?

Your advises are much appreciated.

 

Is this a Discovery 2?

 

Yes, Discovery 2 Td5 2001

 

Does the key unlock the car manually?

 

Yes, but alarm goes off.

 

Locking and unlocking the car three times with the key or fob typically resets it.
