Tag: how to fix BMW diesel common trouble code

If you have a BMW X5 Diesel with codes P2620, P2621, P02CB relating to throttle position this video will show you what I replaced to correct the faults. The first code was P2621 Throttle position output circuit low. This is a very common issue with the BMW X5 (E70) Diesel, I was experiencing a strong shudder when I was shutting down my BMW X5 diesel. Please share your experience and diagnostics, thanks.
