The stability control light is on in my husband's 5-series BMW. I took it to a BMW mechanic for an estimate -- a mechanic I've never used before but they specialize in imports. The total estimate for repairs is $4600 (includes a variety of worn/leaking parts apparently)!! And about $1850 of this is for the stability control. So I'm having a little trouble breathing and my stomach's hurting...my question is this. How cut and dried is the diagnosis? They say that the ABS/DSC hydraulic control unit is faulty and ABS pressure sensor is faulty. If I pay the dealer for a second opinion, is it possible that the diagnosis will be different? And is this estimate of $1845 appropriate for this diagnosis? I'd so appreciate some help here!
