It applied to all F-Type versions within specific VIN ranges. The original offending K309 update was to be applied to all VINs from K00001 thru K29970 (MY14-16).
The JTB00495 fix was to be applied to K00001 thru K22184 (MY14-15), but only if K309 had been uploaded with an SDD version less than 145.7.
Thanks to F-driver on the Jaguar-Club.DE forum for this info.

 

This is very strange. I did not have an oppertunity to drive the car any more until last weekend. When taking it out for a spirited and longer drive this Saturday I found to my disapointment that more or less all the pops and crackles are now gone. It's very different from the short drive home after the JTB00495 fix was done.


I have gotten a confirmation from the dealer that the JTB00495 was applied to my car during last service, but with a very "bad" result - as it now is more mute than ever when I get off the throttle. I really have to work hard to get any pops and crackles what so ever, and it's only a single or a few pops and crackles no matter what I do, and no matter what mode I am in (dynamic, dynamic sport, normal with exaust open etc).


I have booked the car in for a closer "inspection" at the dealer Tuesday next week, as they could not give me any explanation over the phone (nor any suggestions of what they could do about it).


Anyone here with any suggestions?

 

Have VAP send you a tune with full snap, crackle, pop.

 

Can he do this? I thought he looked into modifying the exhaust tuning and decided it was too complex to edit?

 

Only way to know for certain is to ask him.

 

I have always thought that the R has enough "usable" Power, and was not planning on a tune.


However this might be something I will have to reconsider - if no other solution is found, and the VAP tune will restore the snap, crackle and pops...

 

My car is at the dealer today, trying to figure out what causes the missing pops and crackles. They read out the error codes, and there are two lambda probes (O2 sensors) that are giving wrong readings and/or readings outside what is normal and/or slow to respond. This might result in a change of settings in the engine management system, which might affect the amount of pops and crackles.

The faulty sensors might have been caused by the anti-corrotion coating that I had applied last year. Check engine light has not come on.

A lot of "might" but it does make sense. The two sensors will now be replaced, and hopefully with a positive result regarding pops and crackles.

 

So, I'm a manual. I doubt it's a big difference, but:

In any gear, revving tween 3400 and 4200 (approx), let your foot off the gas. Then, *immediately* lightly tap the throttle once again (or twice).

Enjoy!

 

I have had my F type for 2 months and do this alot just to hear the exhaust when driving around on short journeys.

Can anyone advise me as to how bad this is for the car or any other negative issues of doing this?
Not bothered about petrol consumption

 

There is no problem with this. It's designed to do it and your expected to "play".

 

On the MT, try some vigorous acceleration and an upshift at 4000 rpm. Results in a single 50 caliber gunshot. Blam! Glorious!

 

Similar with the AT in Dynamic & Sport when you shift up at 4,000 rpm plus.
It lets out a noise that J Clarkson referred to as "snorts like a hippo". Not really like a gunshot though.

 

In my case, it's a single massive backfire.

 

Replacing the two defect lambda sensors seems to have worked out well.

Pops and crackles are now "back to normal" - and I am truly enjoying it


It did take some miles (50-80 with some stops and starts in between) to drive before the sofware had "adapted" to the correct sensory inputs, but according to the mechanic that was to be expected, and he was correct.

 

Hi,

I have a 2016 F-Type R and I got the car back from 2nd annual service 2 weeks back. They have applied H007 and K405 updates (Which I am not sure what they do). I remember them updating my car last year for O2 sensors.

My car exhaust behaves as follows (active exhaust open):
- Normal mode, paddle shifter, 1st or 2nd gear: the exhaust pops and crackles alot

- Dynamic mode, paddle shifter, 1st or 2nd gear: the car pops and crackles alot

-Normal mode, gear in normal or S, rpm above 4K: if i release gas pedal, nothing happens, maybe one single pop. However, if I tap the gas pedal lightly one or two times right after releasing the gas pedal, i get lots of pops and crackles

-Dynamic mode, gear in normal or S, rpm above 4K: same as above, but slightly more pops and crackles.

Is the above the right behavior for the car exhaust?

 

See my response to your other post! Short answer is yes.

 

Slightly concerned...took it in this AM for the clutch replacement and they also mentioned something about the O2 sensors. Did not think to ask whether it is the problematic 'fix' others have reported...and had not worried about it initially since I was just outside of the range referenced in K309 (VIN is a low K30xxx).

In the interim, I am in an '18 F-Pace. It is new enough that it still has paper plates on it because they have not even received their metal plates used on their in-house loaners.

 

The K309 (o2 sensor update) is a turd sandwich disguised as 5 star meal. DON'T. DO. IT.

If you're the type who drives your car aggressively and likes the sound of the exhaust, you will not be happy. If you typically take it easy in the car, you might not notice.

I for one am still quite infuriated with this whole debacle and would advise you avoid this update at all costs.

 

Some of us noticed no change, though I received the K309b and not the initial one.

 

And some of us had issues that were resolved with v2 of the software update.
