The customer reported that the vehicle was sluggish taking off on every drive and had a whirring or whistling noise while accelerating. Check engine and traction control warning lights had also been noted. The battery had been replaced a few weeks earlier, and an oil service was completed 2 days prior.

An initial inspection and road test confirmed a lack of power on acceleration, along with a noticeable whistle or whirring noise under load. The symptom pattern was consistent with a charge-air leak in the turbocharger and intercooler system. No specific fault codes were documented in the job notes, but the warning light history supported an engine performance-related fault.
