Ticking Noise in 2015 Z4

Hi All,
Just wondering if any one can point me to root cause of a ticking noise that has developed just after i had the dealer repair heat exchanger valve. it is only during idling and low speed, noise turns up and down as i press the gas pedal.
i have a audio/video file, i wish i could upload.
thanks in advance.

i did some further search on google, and the noise might be "pulsing", possibly related to the flap in the exhaust pipe.. anyone have suggestions.
