Excellent explanation. A lot of the anxiety about DPF and EGR concerns is greatly reduced by real-world instances such as yours. Frequent maintenance and safe driving practices have a significant impact. I appreciate you sharing your story.
Well spoken, Dave. I've observed the same thing with prolonged service intervals: if minor seepages are ignored for a longer period of time, they grow into larger issues. Without the main dealer price tag, a competent independent BMW specialist can typically determine if the problem is actually a turbo or merely a seal.
I agree. I've also used a square configuration in the winter and found it to be very effective, particularly in the snow. In addition to making life easier, going a little narrower with the appropriate offsets typically results in cost savings.
