Hi all I hope somebody can help me I have just bought 2 weeks ago a xf s porfolio she has been running like a dream up until today when I popped into sport mode and dynamic the the noise started it sounds like a scream or a squeal when you press the accelerator but only around a certain rev range not a continuous noise this is my first jag and I’m gutted to be hearing this so soon in my ownership I so hope somebody has some advice or can recommend a specialist near me I live in Peterborough many thanks in advance
