Hi gents , many thanks for your replies , Steve. I have been reading the many issues facing this model ( the dreaded diesel ) , I have contacted my local lexus dealer and they say my car hasn't had any recall , ( not aware of gasket issue myself 5th injector ? ) was this a lexus recall ? , must admit my local lexus ( jemca sidcup are pretty much stuck up and a little unhelpful ) I did have a major major service done there (£ 700 ) and they picked up usual discs and pads , caliper etc , rattly heat shield and that was it ( incidentally had my brakes discs , calipers done in Hungary at a Toyota dealer ( 300 all in ) . They didn't do my heat shield as they wanted£120 for putting two bolts in ( halfords did it when they put new tyres on . Zoran , blocked injector ? I use premium diesel would it still be worth putting an additive in on next fuel up ( millers etc) . Thanks
