Regaining 'snap crackle and pop' in F-Type S V8 after O2 sensor campaign
 

Has anyone had luck getting the exhaust note back to sound quality you had prior to the O2 sensor campaign?

I've asked my dealer as recently as 2 weeks ago and was told another update has not been made available from Jaguar to address this. I brought their attention to several TSB's I read about on these forums but they insist I have the latest update and they acknowledge it reduces exhaust sound level and acceleration for engine protection from carbon buildup.

But then again I keep reading there is a fix. What is the real truth regarding this?

There is only one TSB, not several. I lost all pops and crackles after K309 and regained them all again after the TSB was applied.

Have you quoted them the exact TSB #?
