Lost my crackle and pop

Hi all,

So last Saturday I went for my first good drive in the MCS, it was popping and crackling all over the place detailed the car on Sunday and ever since quite as a mouse

Same conditions, everything hot, the only difference was in the ambient temperature and the fact I had polished the exhaust so it was like a mirror.

Any ideas or do I need to take a trip to the dealer to ask why it has stopped popping!

Help!

I don't have an S, but does some of the sound of the engine not come from a digital track played through a speaker in the rear area of the car?
Maybe a wire has fallen off!?

Apologies if that is just rubbish, sure I read it somewhere though!

In the old days of adjustable carburettors you could make an exhaust make a popping noise on the overrun by excessively leaning off the fuel mixture. Perhaps your ECU had decided to richen the mixture fractionally for some reason.

You polished the exhaust? Now you've done it. Of course that removed the crackle and pop.

Go to the dealer and have them apply official MINI Exhaust Grunge. You should be popping and crackling again in no time.

And stop polishing the exhaust.

The crackles and pops are REAL. Trust me. Not some improvised noise.

Could be ambient conditions playing a part. Mine was popping away this afternoon though on spirited drive home

Been driving my MCS for a month now in sport and still have never gotten the pop or sound. What am I doing wrong? I'm in the US, could that play a part? I didn't spec the JCW tuning either.

hi ,

I don't have a MCS but as I understand the popping and crackling is available in sport mode but on the overrun , so you have to shut the throttle abruptly at high to middling rpm. They overfuel it to make the sound

I hear it in my 2015 MCS occasionally, under conditions like @CO2slave describes.

I don't believe that the snap, crackle & pop comes from Active Sound; you can hear it from outside the car. The only thing I hear from Active Sound (as far as I can tell) is the growl under hard acceleration.

But then my ears have heard better days. Maybe I'll enlist a teenager to tell me if AS is popping or not...

@CO2slave has it right. Best way ive found is to drop it a gear, especially when heading downhill and not under acceleration. Other option is to quickly lift off the throttle at high revs

Wife's roadster s even pops between up and downshift gear changes and with the roof off can really make you jump.

Surprisingly delighted to have moved to an f54((with a r59 in the fold for fun!)
