318is noise

[Finto_316]

hi,
under medium to hard acceleration we have noticed a high whine ,on the drivers side of the car, also theres a noise on the drivers side on accelertion anyway we had the same noise on our old 316i
heres a video of the tapping knocking which we think is a high whine,also if you can hear by the sound of the engine i dont think it sounds right anyway, hard to describe. bought a chip of speedtouch so seeing if that will liven it up ha
