I have bought a 2013 2.2 diesel xf jaguar(believe its called a sport) and i realy dont trust the glue/compressor thing. not very good on internet,ref;looking for spare wheel or a normal one would be better. 18" 245/45/zr18 are the tyres at moment dont know why the z. derek since i bought the jaguar the eco stop start has only worked 2 or 3 day's have had it back for updating twice.(gear lever mods.) i understand it can be very sensitive but when will it work normal.
