It's gone! I drive in sport mode all the time because the throttle response helps with heel&toe, and I LOVE the pops and burbles.

But since yesterday, pops and burbles disappeared... Sport mode button still is making the steering heavier, and throttle sharper... This is so weird!

Anyone with similar experience?

ps: this is a 2011 Cooper S.

 

Just a thought but it might be fuel quality. Try using a higher grade maybe that will do the trick?

 

Thanks for the reply. I pretty much always get my fuel from the same Chevron station by my office, and I always use the highest grade.

But maybe they had bad fuel in my last fill?

 

Was your car up to operating temps? The way the p&b works, it drops unburnt fuel onto the hot exhaust manifold, as far as I understand it.

 

The car was at operating temps. And I think you're right about how the p&b works.

Maybe your car just isn't feeling talkative today.

 

I've noticed that mine is variable with some days being louder than others. I haven't tracked it yet to see if there is a pattern.

 

Ambient temperature effects my pops & burbles. In about 70 - 80 degrees there are times where I will get an extremely loud pop, almost a backfire. In the high 80's and 90's its usually justs the standard pops.

 

a new MINI is loaded with burbles and pops

just so many

you used yours up

a classic has an unlimited amount

 

Well, I got my pops back, shortly. Then I got a check engine light. Sweet.

 

How I wish I could rid The Dread Pirate of the backfire noises!

 

Dunno why but when the AC is on mine doesn't pops, when is worm(70 and up) doesn't pops..

meh

 

Love the P&B's. Once in a blue I will get a backfire like pop.

 

Did the OP get the codes checked to see what the issue was?

 

well mine used to pop and gurgle in the morn cold start but after the sensor bulletin stuff was done it won't accelerate gurgle and pop like prior. now it only does it at temp and when traveling. They say nothing was changed
