Hello all.
Just bought a 75k miles 2018 1.6TDI which also makes an intermittent high pitched squeal from the right / rear side of the car. Turning the engine off & restarting sometimes stops the noise. Car is going back to the garage where we bought it from & I will update you on outcome. Not holding my breath as they sold the car with 1 winter tyre (FOS) 1 part worn (FNS) & 2 cheapo-no-grip on the rear!
