Would be interested because my 135is with about 65,000 miles on it is an N55.
There are a very small number of threads maybe 6 on N55 bearing failures at N54tech, the BMS JB4 modified forum, but not many out of the thousands of modified N55 posts there. |
My girlfriend previous X3 35i had rod bearing failure at 105k miles.
I went to see a 2013 335 with a friend and engine broke previous day, rod bearings.
They seems to break around 105-120k miles if not maintained well.
