I bought a second hand 2003 MCS and noticed that it has an exhaust burble when shifting from 1st, 2nd, or 3rd (possibly higher but have not paid attention to higher gears).

I read that this sound was engineered in the 2005 models but was wondering if its something that has possibly been retrofit to my MCS with a simple ECU update?

Thanks,

Does it have an aftermarket exhuast or one-ball? IT could be and ECU (how MINI got it on the 05s and 06s) but just about any exhaust mod will also create the burble

 

I am pretty sure its 100% stock car. I picked it up off of a lease which probably would not have been allowed to make any modifications.

 

stock has a bit... very faint, but it is there

 

maybe you have some sort of exhuast leak?

 

my 03 with Milltek burbles.

 

 

Yup, it's completly normal, but like you said, they changed the ECU around in 05'+ to make it burble even more. The 02'-04's do it to some degree, but I can only hear mine when the doors are open.
