While accelerating away from a roundabout heard a low 'bang' from engine and a serious loss of power from car. Managed to drive home(slowly) with intermittent loss of power. Had it to local mechanic and he thinks it is either the turbo or an intercooler pipe has blown?? There are no warning lights showing on dash but obviously something wrong. Car is on an '06 plate with around 90K on the clock. Any suggestions or anyone experienced similar problem would be good to hear from you reagrding what sort of bill I could expect.
