Have a Gen 2 leaf and the brakes are very grabby. You try to brake and you get nothing nothing nothing, and then bam it locks up and you go from moving at a decent speed to completely stopped.

So the nearest place that can do a $200 firmware update is 350km away. THe range of this thing is about 100kms at 50kph on the flat, if you're lucky.

Anyone has any ideas how i can get hold of the update file and other equipment to update it?

Cheers

In Auckland I have Official Consult Tool (Dealership level scanner) and can apply upgrades to Nissan cars, program various blocks and program keys (even if all lost) Leaf included. I can reprogram LBC and VCM, including turning 24kWh into 30kwh version. Also can reprogram 40kwh LBC when cells are replaced. I do have official brake upgrade file, but I never ever offered it to anyone, nor ever applied it.
Simple 2 reasons are:
1) Brakes are complex system and has to be diagnosed from various points of view, mechanical, brake fluid, calibration, etc
2) There is simple (user performed) procedure to fix grabby brake effect. No tools needed. Google it. It had been discussed on FB and successfully applied by NZ Leaf Owners without the need to do any firmware upgrade.

FYI: The official upgrade had been issued for sub zero temperatures in places like Canada and USA, can be officially purchased by any mechanic, but IMO it is not applicable to NZ climate.
P.S. Some ppl in South Island saw it as a business opportunity perhaps applicable for short winter months in places like Dunedin and Invercargill, but for the rest of NZ it is nothing but a rip off.

Sample size of one but I got the firmware updated on my 2014 uk leaf when the breaks starting grabbing and it made a marked improvement.

Well, take the brake computer out and courier to those who would happily accept your $200. What is the problem with that?
FYI You do not have to drive the entire car, just send them the block.

I do reprogramming (conversions to English) of various blocks from various car makes and models for entire NZ, sending them back the same day. From programmng point of view it doesn't matter what block it is. Those who offer those upgrades technically should be able to reprogram your brakes...
