BMW M3: Connecting rod TSB, "could puke bottom end out"
January 09, 2008
I received an e-mail this morning in regards to a TSB ( Service Information B11 02 03 ) for our new used Long-Term M3, and to all M cars with early-- produced between October, 2001 and February, 2002-- S54 engines. The oil-pump and connecting rod bearings need to be replaced or, as was so delicately put in the message, the car could "puke its bottom end out."
Some sleuthing from an eager staff member (SubyTrojan) with connections at BMW, confirmed that our M3 was one of 4,000 cars involved, and was repaired in the summer of 2004, just over a year after the introduction of said TSB. The mileage was 23,361. We don't know if the car exhibited the tell-tale knocking that precedes puking.
With that out of the way, we're free and clear to continue driving this car the way BMW intended.
