2013 Ford Escape 2.0 se with approximately 90k on the clock, following service where fuel evaporate valve was replaced and engine oxygen sensors reset the car has made a rather odd high pitched grinding/squealing sound at the start of fairly heavy (not aggressive) acceleration then again when lifting foot off accelerator. Since the service there is also a more pronounced whoosh from the turbo. Been back a number of times and sound persists. Can not be heard when giving throttle a good stomp in either Park or Neautal only Drive or Sport though just occurred to me not tested Reverse. No odd engine sounds during cruising or slowing down though engine breaking when lifting off the accelerator feels a little more pronounced. No shaking or odd gear changes during acceleration, slowing or cruising.
Was wondering if anyone has any ideas what could cause this. It sounds rather corse and damaging though dealer doesn’t seem too concerned, probably wants to charge me an arm and a leg making extensive repairs during the next service just around the corner.
Many thanks in advance
