Took delivery of new X3 in December and within a few weeks noticed a knocking sound coming from the drivers side front end when driving on or off the drive.
I took it to the dealership where it was diagnosed has having a faulty steering rack. A new steering rack was fitted and everything was fine. A few weeks later the same knocking sound was back.
As before I took it to the dealership and the same problem was diagnosed. It needed a new steering rack. A new steering rack was fitted. Four days ago the knocking sound returned and after diagnosis it turns out to be a faulty steering rack.
This vehicle has less than 3700 miles on the clock.
When I first heard the knocking noise I was putting it down to the vehicle being new, creaky plastic or not enough water in the windscreen washer bottle.
The dealership has been great. The service I have received has been second to none. Customer Services at BMW UK do not want take responsibility and have got slopey shoulders.
