I have recently purchased a 2013 XF. I have a problem with the door mounted mirrors. I have contacted my local dealer, Guy Salmon in Coventry and spoke to Michael, who was very helpful, he informed my that the original purchaser did not take the optionof automatic folding mirrors. However the ability to fold the mirrors by simultaneously pressing the mirror adjustment switches was a standard fitting on this model. Sadly this does not happen on my vehicle. Any advice please.
