I'm running my Forester Turbo in at the moment and have accidentally taken it above 4k rpm (not redlined it though.) I'd like to know what the dealer can find out from plugging into the ECU. Is it done as a usual part of the service, or only when needed? Can he tell how well I treat my car?
regards,
Toerag

I don't think they can tell those things, however, they like to make things up. But you should never trust anything you hear at a dealership, anyway.;)

Yes, your ECU does store memory, reset it before you take it in for service.

If you have trouble codes in memory then the freeze-frame data will show what the RPM was at the time the code was set. There is no on-going recording.

Forester Turbo? Okay, we hate you now.;)

The 4,000rpm break-in limit is an advisory, it isn't strictly enforced. If you bring the car in for service in a few thousand miles they're not going to dink you for it.

"You hit 5,000 rpm once with 700 miles on the car. No Warranty For You!!"

No worries.

Julian, each country has its own laws and practices for regulating manufacturer's warranties and claims. I don't think you can automatically extrapolate based solely on how SoA warranties work here in the US. For instance, in some countries it's perfectly legal to require that all scheduled service be performed only at authorized facilities and that a certain brand of motor oil must be used in order to qualify for warranty repairs.

Point taken:)
