Is it possible to disengaged the autobstop start on my d5 and if so how
I find really annoying when it switches of for a few seconds then back on
Say at a set of traffic lights
Hi Andy,
You can turn it off in the menu but it will only last until you start the car again.
Unfortunately the stop start defaults to always on every time the ignition is cycled.
The car can be configured to retain the last setting but this will need a GAP IID tool or similar that can edit the car configuration files.
If you do want to do this let me know and I’ll find the settings you need to change.
It was the first job I did when I got my D5.
Hope this helps.
Hi mate
I've got a gap lld i need to get it updated from a d3 to d5
Haven't had chance yet , but yes defo want to get it switched off
Find it really abandoned keep thinking of a starter motor !!

You can program the function of the "favourite " (diamond) button on the steering wheel to turn off stop-start. You'll still need to press it every journey, but it's just one button press.

Hi, yes I’m sure it can’t be good for the car and used to drive me mad if I forgot to disable it.
The details are here in this excellent post from Mole:
Certainly for the facelift cars you will need the current GAP tool as unfortunately the newer cars use a different protocol. Not sure about the earlier models.
The MY2017+ D5 needs the G4 version of the IID tool. The G3 version has limited functionality on a D5, the G2 version has even less. Not sure if you can upgrade the G2 version to the G4, I'd email GAP support and ask first. Currently, the IID tool doesn't cover MY2026 models.
I upgraded my IID tool from the G3 I bought for the Disco 4 to the G4 version via the GAP website. The upgrade costs £220 and involves you sending the G3 version back to GAP Diagnostics in Canada (postage is included in the cost), they then send you a new G4 version by return post.
The upgrade isn't cheap (cheaper than buying a new one)...but you get what you pay for with an IID tool, it does exactly what it says on the tin. I even bought a fancy schmancy hardshell case for mine. eBay link
...Custom designed, 3D printed to very high quality in ABS and sold by a D5 owner and forum member. You know you want one...

The newest JLR vehicles (including the current D5 models) have locked down the CCF. Making even the Gen4 IID just a code reader on these vehicles.

$600CAD is roughly £320...which is still a couple of hundred quid less than buying a brand new IID tool at full price (£520). Gap have just added £100 to the cost of replacing a later, and still supported, G3 version rather than ask for full price.
To me, that's a pretty reasonable compromise considering the G2 was discontinued a fair while ago. GAP keep a customer, you get a fully functional G4 IID tool. Being a VIN locked tool, they're also giving a better value deal for your G2 than you could get selling it privately.
Don't get me wrong, as home mechanic tool purchases go...especially a VIN locked diagnostic tool... £320 is a hard swallow.
It's still a fair bit less than full price though...I was in a similar position when updating my G3 and being faced with £220 for the pleasure. Having used the IID tool as much as I did with the Disco 4 though, I bit the bullet and forked out.
I never owed a D4 ,had the d3 almost 14 year , the tool paid fir itself
Almost the first time I used it , gap are saying its absolutel
but I could always update it , clearly there's a lot more going on
around a d5 so I guess ill have to bite the bullet as I'm sure at
Some point im going to need it , no doubt it will save me a
Load of money
