Difficult to overrev with a limiter in place... I would request the printout.

There is a wealth of info available here

Nope, its easy to overrev - just select the wrong gear (i.e. 1st instead of 3rd, or 2nd instead of 6th etc) and the engine will spin up to whatever revs are physically required and self-destruct.

The ECU will record level-1 and level-2 interventions. Level 2 are ok and just indicate when the rev limiter is hit - which is perfectly normal and what its there for.

Level-1 mechanical overrevs are when the incorrect gear has been selected - if this is the case then your warranty is invalid, you will not receive any goodwill claim and you're gonna have a big bill. A GT3 owner recently was asked £27K for a new engine because of this.

Ask the OPC for a printout of the codes and see if there have been any level1 overrevs.

There is a bit more information on the PCGB forum here:

Greig has it right, but reversed. Range 1 means nothing other than the rev limiter came on to protect the engine from any potential damage. Range 2 is not so good.

But there are Boxster with bearing failures that have no range 2, and Boxsters with range 2 that run fine. Bearing failures are known to happen which are unrelated to rpms.
