Is there anyway to check yourself if there is an issue with the EAKs? So after you got this fixed, your burbles returned back?

My car has some quiet burbles but they only sound like they're coming from the right hand side. Can't hear anything from the left side!

I let off the gas there no any burbles on traction mode.

Do you have MPE exhaust? If so then make sure the flap is open. If you don't have the MPE, there's a secret way of opening the flaps which you can YouTube, but I believe is you press button once to put into MDM and then press gas pedal fully once (when car is switched on but not cranked yet). MDM with flaps open gives the most burbles

Thank you very much

You're welcome. Let us know if it worked. Here's the video of the secret exhaust mode or to open the flaps on a non MPE exhaust:

everything was fine until I replaced the new charge pipe. I'm not sure it had anything to do with this. I have the Stock exhaust.

That's strange! When I switched from the stock chargepipe to a cvt chagepipe, the burbles were a lot louder! I have a M2 Lci with M Performance Exhaust and Wagner decat Downpipe
