problem #1

Jan 232021

M340i X-Drive LX 3.0lV6

  • Automatic transmission
  • 500 miles

6 days without car while they try to find problem, I just bought the car about 1 month earlier.

They claim resetting BDC unit and replacing key fob is a permanent fix. But no explanation of what caused BDC to need resetting. I'm guessing BDC unit needs replacement as in other years they had problems with this unit shorting out and being replaced. It's a very expensive unit, so I guess I'm the guinea pig to test it out. It's never the customer that counts first but their profits!!
