Heres a funny one for you to answer I have found another minor but annoying problem with my beloved 407. When I come out of work I turn left onto the main road and shortly after about 100 yards reach a roundabout which I turn left at. Every time I turn left at this roundabout my traction control cuts in for a few seconds as I manouever round the left hand bend. It only happens once and other left hand turns are ok without any problem. Its funny how this occurs same road conditions dry or wet. Cuts in once then disappears about a minute or 2 after start up is it a sensor fault if so where is it located?
