Hi Guys, This is my first time on Zroadster, I own an x reg z3 2ltr . I am the ripe old age of 86yrs and love driving the z3 . I have owned three z3s over the last 20yrs , my current one was bought at a police auction , and although the mileage was a bit high 150.000, The car ran perfectly for two months and then went into limp mode . It has been to two different garages . The first one said it was throttle body this was replaced with a second hand one and the car ran perfectly for 10 miles then went into limp mode. The second garage replaced the disa valve which did not cure the problem, the latest is I have found a garage who deal with vehicle electronics and have said if they cannot find and cure the fault there is no charge . So hopefully win win . Will report the outcome Cheers
