a friend of mine has a vw passat 4motion 130bhp. real fresh car. he had her in the garage the last day and the mechanic noticed the exhaust clamp was slack. iv never noticed any unusual noises from her before so was suprised to see this was the case. he tightned it up and said no more bout it. next thing you no shes "kooo-ing" away through the gears. i always thought that the koo was caused by back pressure, this supposedly causes damage to the turbo, therfore vw wouldnt send a car out standard "kooo-ing". what actualy is causing this koo sound, is it something to do with the exhaust and is it able to recreated on other cars?
