Took my 2014 328d wagon to my dealer last week. I've been using a quart of coolant every 3 weeks. After checking it, I was told I definitely need the EGR module.
But... there isn't one in the entire USA. They were going to contact Germany. The next day I was told they are completely back ordered in Europe.
Then I was told... "you cannot drive this car!" Do you have a second vehicle?"
They would have given me a loaner if I needed one.
MY CAR IS IMPOUNDED until they complete the repair!!! It might take a couple of months... or more!
