Need help with power brakes and P2187
Hello, I am new here and just purchased a 2004 X5 4.4 I love the car and it looks like new. I got it cheap from a wholesaler because it has a few issues I am working through. A couple of days ago, the check engine light came on with P2187 (left bank lean) and at the same time the brakes got scary. The brakes at first feel fine but lose power assist before coming to a complete stop which means you really have to stand on the pedal to get it to come to a complete stop. I am checking out the obvious but wanted to see if anyone has ever experienced this and what the fault was. Thank you!
