Jaguar Neutered My Exhaust!

[PhilB]

Is there any truth in this? My system lost all of its settings and saved places etc after the update, so is it true that it has simply reset and just needs to "learn" my driving style? I have to be honest, this is the first I've read of F-Types learning and adapting to how you drive.

There was a software update some time back that affected the exhaust system.
Look at the link in Tel's post yesterday.
The infotainment updates (H251 and the latest 19C mentioned here) are purely infotainment so won't affect the exhaust.
Those updates will also change settings back to default on some things (sound settings come to mind)

Thanks PhilB. I wonder though whether the software in my car was quite old, so updating to H251 also would have included a previous update that did effect the exhaust? I'm hoping that, as per the thread on Jaguar forums, this is all just caused by the system reset and that the full roar will come back after a bit more driving.

I think you need to forget H251 as that is an infotainment software update to enable later cars to have SOTA updates (sent over the air) purely for the infotainment system which is a standard thing on new cars.
If there has been an update that affects the exhaust in normal driving then it could have been applied by your dealer at service.

I'm going to spend a bit more time driving the car to see if, as per the Jaguar Forum thread, that makes any difference. But if not I'll be having a stern word with the service manager!

Who'll probably say he had to do it as Jaguar says it's necessary. The fact that it makes money for the dealer has nothing to do with it, of course.

Nothing to do with this?

Mine is MY18, so I don't think mine required that change. But who knows?

Mine had H136 - "Pass by Noise in Latched Special Programs Mode" applied when I had the rear parcel shelf replaced under warranty (WTF!) which stopped dynamic mode being remembered for up to 6 hours, but didn't adversely affect the pops and crackles. Later models have more stringent regulations to meet, and I hope they don't ry to retro-fit them to older models. I'm avoiding dealers as much as I can.

By that logic, if you wanted to test to see if your car has already been "neutered" :lol: in the past, could you switch it off in dynamic mode to see if it's remembered for up to 6hrs later?? :?:

You could certainly test that the dynamic mode remembrance had been removed by that method. When you go back to the car the ambient lights initially show red but no dynamic mode set - the message display shows "Dynamic mode off" or similar. As I said earlier, it's not neutered the noise.

Oh right, sorry - didn't see your earlier message Re noise

Quick update for you all - I've done just over 120 miles since the service and have been driving in a "spirited" fashion (averaging ~16mpg), and the exhaust noise is definitely starting to come back. The low end rumble that was missing is audible again and the gear shift snorts are also returning. It seems that the car really does learn from how you drive, and Jaguar really should make their customers aware of this when they carry out servicing!

I have a service due next month on my 66 plate R AWD. I think the 2016 models are the last to be untouched by Jaguar with regards to forgetting Dynamic mode on start up and any dumbass exhaust restrictions etc. Will ask beforehand which software updates are to be downloaded (if any) at the service.

Nope! Mines a 2016 model and they updated/removed dynamic mode memory from mine.

There are 2 different discussion going on though I think. The update to remove the dynamic mode memory is not related to any update that mutes the exhaust when driving etc.
All this update has done is remove the memory so when you start the car you have to immediately press dynamic mode.

My car hasn’t been affected by any noise loss. That’s something different that affects later models I believe.

How long ago did they apply the change on start up?

My car was serviced last year with zero changes. I don't think my car has any outstanding alerts and my VIN numbers shows nothing outstanding. Maybe it depends on how late in 2016 your car was made as mine was made in early 2016 but wasn't registered until Sept 2016.

On a pedantic point, the car does still remember dynamic mode for up to six hours (watch the ambient lighting stay red when you get back in the car!) but turns it off when you start up. Same effect, but the car doesn't have amnesia.

It’s when they do any warranty work. I had the telematics module replaced as dash displayed “limited sos functionality”. I was told (for right or wrong) that they won’t fund any warranty requests unless software is updated.
I didn’t know until it was done. I did complain and took it up with Jaguar. At the end of the day the car still sounds the same I just have to press the button if I’ve been driving in dynamic mode and restart the car within 6 hours.
I just wish they would give me the option before they go ahead and do these things. I have been very clear to them NOT to do anything which affects sound in my car without my consent.

My indie did a warranty repair and gave me the option of a flagged software update, warning of the risk to the exhaust sound. Didn't do the update just in case.

I see, so as I'm out of warranty then there shouldn't be any issues with stupid software updates. You're right about being frustrated with not being advised beforehand about the change that would occur.
