I have had the EGR cooler in my 2015 X3 replaced 4 times since October 2019. I paid for the first one and the rest were under guarantee. It is faulty again. What could be the cause?
Hi, would like to know why you had the egr cooler replaced. Was it leaking coolant into the egr, was it smoking, etc.? Also, was it a 2l diesel or 3l diesel?
