not sure about the engine management update,but my brakes are shit hot! all the time,
engine update may have been done at the last service about 9 weeks ago but im not sure as ive only had the car about 8 weeks,and im not sure as to get a new filter cos i dont want to void any warranty that i still have, which is about 17 months,so i supose i will have to wait for the warranty to run out before ant major tunning goes on
cheers
steve
