. . . warranty? Searched old posts on this, and it seemed as though BMWNA had taken the position a single over-rev voids the warranty.

Any input would be appreciated. . .

No this would not void the warranty. The rev limiter is there to prevent the engine from over-rev. It's in cases where the rev limiter can not control the engine from over-rev by limiting the air/fuel intake that you have a problem. Such as when you downshift into 2nd while going 85 MPH or something like that where the rear wheels will drive the motor into an over-rev condition regardless of how much fuel/air the engine is getting. This problem is supposed to be eliminated with the SMG Drivelogic, but it does exist with a regular six speed. <br><img src="">

if you miss a downshift & accidently overrev the engine but cause no harm how would that constitute a case to void warranty? how would they ever prove it was from a downshift if no damage occured? the rev limitters have been questionable at best - plent of overrev data from smg cars - etc etc - also - the overrev c/h been accomplished by their own techs during 'service runs' -

if you blow the engine & upon inspection evidence reveals significant valve-line damage then you have something to discuss with the factory - hoping for help at that point - but if the engine blows b/c of the bearing failures i doubt the factory will be discussing your warranty at this point - they seem to be replacing the blown engines no questions asked when it is a lower end issue
