What a frustrating few weeks.
My XF started to make a wobbling noise from the front near side wheel area. I asked my main dealer to have a look and they informed me the wheel was buckled. So I paid and got it repaired. The noise continued, so I took it back and they then informed me that my front wheels were very out of balance. So I paid and they balanced them.... the noise continued. I took the car to a local but well respected Indy tyre dealer to have a snoop. Low and behold it was a defective tyre, I replaced both...no noise!! Hurrah...
Poor showing by a Jag main dealer!!
