Hey my girlfriend and i have just bought a nice rs4 only problem that i have with it is the flat tyre warning light is on. i have tried resetting it on the dash with no joy so i popped along to my mates garage and put it on his diagnostics it came up with a couple fault codes being
"ERROR CODE : 1521 (tyre pressure sensor (ATT))"
"FAULTY ERROR CODE : 1833 (antenna for rear tyre pressure supervision (ATT))"
Anyone got info on these as i dont know what needs replaced... or can i turn this system off???
thanks doug king
