Thanks Paul. If I get it sorted I'll let you know!

Hi Paul,

There are no codes and no warning lights! Just drives like a dog sometimes. Always seems to be in the wrong gear and who wants to drive at 30 mph in 8th gear @1000 rpm! Something needs to change and I thought a remap may help. 

Hi Frank,

Thanks for responding! I think that my comment mentioning "nearly a year" is not that far off the mark! It is now June and the original post was made in July and my follow-up at the end of May!😁. It is still driving erratically and overall driveability is poor with the original statement still valid. The only way to drive is using the sport mode with paddle shift so that it is not in 8th gear doing 30 m.p.h. @1000 rpm causing the engine to stutter as it is under too much load at low revs (I am a qualified Techy!).

I still think some kind of remap may be the answer, but I haven't had the chance to locate someone yet due to circumstances beyond my control (health issues and redundancy). 

Wow! Best part of a year and no responses. Not much point being on here then! Will try and find a more friendly group elsewhere!

Hi, I'm new on here and was wondering if anyone can point me in the right direction or offer advice. I have an XF Sportbrake 2018 25t. I have noticed the following when driving:

1. Sluggish/irrational throttle response
2. Auto box that doesn't know what gear it should be in when pulling away
3. A kind of "disconnect between throttle input and gearbox reaction.

I have spoken to a few people who have suggested a remap may address all 3 issues. Can anyone back that up or suggest someone that I could speak to on this subject? I don't want to approach Jaguar direct due to reading other peoples responses regarding "no fault codes so no issues" and the obvious main dealer hourly charges! My car has only done 26000 miles and has full history so well looked after. I am based in Buckinghamshire so any local contacts would be great!

Thanks in advance for any help/suggestions 🙂

Apologies if it was covered already. I have a really annoying issue with my XF Sportbrake 2.0 i 250

The car is very sluggish between 20-50mph. Seems like it is always in the wrong gear to the point that the car judders.

For example I could be driving 30mph and RPM would drop to about 1000 and the car will be in the 7th gear (can see if use flappy paddles (shift up and it shows one gear up from what is it now)

My pressing the accelerator gently the car would judder and then either drop one or 2 gears or start accelerating in the current gear which make is feel very sluggish.  

This behaviour is present when driving gently or in traffic. Once the car is driven more aggressively geabox shifts and RPM seem to be fine 

Sport or dynamic mode make no difference to timing of the gear shifts.

It is important to note that the car got progressively worse (only had it for 6 month), so I believe this is something to do with gearbox adaptations. 

Jaguar obviously can't fault it as there are no errors present on their computer and refused to reset gearbox and claim the behaves as designed.

I am very frustrated to the point I really hate driving this car. I can't believe Jaguar would design something as awful as this.

Anyone had similar experience or knows how to reset gearbox adaptations ?

Many Thanks

I have the same issue - Jaguar XF Sportbrake 2018. Looking to see if I can get a remap that may help. Anyone with any sensible ideas?
