Hi Guys , Newbie here I'm afraid , Bought a Jaguar XF 3.0S Portfolio , private sale , 78k on the clock , 58 plate in Black . spent 6 months plus looking for the right one !!! . I have had the car some 6 weeks now , the last 4 weeks its been in and out of my mech's garage three times !!! Restricted performance comes up 4 wks ago ,driving along bypass doing 50 mph goes to over take , and up pops the red letters restricted performance , phone AA , turns out to be code Poo6A , carries out repair , resets , all fine , then next day it does the same thing overtaking again !!! . Into garage , for repair , replaces black !! air filter full of debris , replaces oil in engine as this was black ! (serviced by Jaguar Sept 2014),resets fault all ok again for a few days , then restricted performance lights up again . Into garage , for repair , replaces both mass air sensors , one was grey/black colour , resets fault , all ok again , few days later restricted performance lights up again , this time we sense a rubber burning smell ? into garage , for repair , checks out DPF filters , need cleaning !! , uses special cleaner from Germany for DPS cleaning , all done and test drove by mech , worked well drives great !! , then all of a sudden restricted performance came on , checked code , we now have P2263 ? , We have done all we can at the garage , could any one recommend a good independent garage please in the Gloucestershire area , other than HA FOX of Chel , Parents used them for there XK8 , not very good . Many thanks in advance Paul
