Anyone got any experience with SDD the diagnostics package ?

My 2015 XJ keeps displaying the Adaptive headlights warning, my IcarSoft is showing that the Swivel motor circuit for both headlights is the issue, so I suspect it is a wiring issue.

The Icarsoft shows an option to test the lights but says not supported, the lights are working ok and doing what they should.

It's been a couple of years since I last used SDD (sold my XKR in 2023) but I might remember some stuff. What is it you want to know?

You could try the Jaguar forums, jaginfo.org is mainly UK based with some SDD users

I managed to do what I need to do with my ICarsoft code reader, the error looked for all the world like the tech bulletin I found, but did more digging and found a suggestion that it may be because I didnt reset the BMS when I fitted a new battery in April.

Ran through the process on the code reader and no flashy AFS warning since, which is very pleasing.

Saved me three hours kicking my heels in Macclesfield whilst it was in with the specialist (Horner and Hudson, very helpful btw) and the £108 for hooking it up, so with that and other bits and pieces, its already paid for itself.

I think a specific code reader is absolutely essential for cars like this once out of the dealer network/warranty and you are trying to run them cost effectively. I work in IT and am fairly technical with cars so I find it fairly familiar.

Would like to explore SDD though but am a little wary, does seem to be a minefield for the unwary.

Glad you got sorted.

SDD is potentially hazardous, yes. Due to bitter experience I would say stay away from the cheap eBay Mangoose clone cables and definitely don't use one of the SDD installs in a virtual PC. Much safer to have a proper hardware interface (Diagnostic Associates DA-Dongle is fairly cost-effective) and use an old laptop which you can install XP or Win7 on and keep it solely for that purpose, i.e. no other stuff installed. Plenty of folk will no doubt say "rubbish I've had a cheap cable/VM install and never had a problem", but I have and I'm sure it was down to that. I'm not the only one either, seen fried ECUs due to bad cables. If you're just doing things like clearing fault codes then you may get away with it but I definitely wouldn't risk flashing modules with anything other than a proper interface.

Also worth having a proper battery tender for any sort of prolonged diagnosis and absolutely a must if reflashing modules, definitely don't want the battery letting you down whilst doing any of that.
