I had the front wheel bearings changed on my BMW X3 2005 and the lights ABS, 4x4 Brake and Tire Pressure lights have come on. they do not turn on immediately but after a few minutes when I shift to drive they come on. Is it safe to drive like this, what could be the possible causes. My mechanic says that the bearings I bought were made in China although per the supplier these are a fit for the model I have, I bought them on ebay for $ 20 each.
Can somebody please advice?
