High RPM noise....sounds like radio, but radio is off...
Hi.
I believe in breaking a car in with the motto "drive it like you stole it."
Anyway, in 2nd on my 2006 RL in M shifting mode, in gear 2 at 5500 to 6500 I get a weird noise coming what sounds like the engine (valves).....the car is 20 minutes into a highway cruise, so it is well warmed up.
800mi on the odo.

I paid for premium gas....but you never know if the station is really using it.
It was a "new" sound to me...running an S4 with a high compression ration v8 with the same gas station's gas did not cause this....
Good thought, I'll go to the local Sunoco and get 94 gas asap.
Is there a "record" of such events in the ECU a la Audi......?
TIA

Are you sure you're not just hearing the VTEC noise? The engine sound changes right around there...
And BTW, "drive it like you stole it" is a lousy way to run-in AWD clutch packs and sophisticated valve trains.

Thanks for the info....dealer told me to do so....5500 seems fair.
There were huge threads on this topic on the Audi forums... 5v engines and torsens....not an issue. I think Honda is just as good as Audi.....but I respect your concerns.

UPDATE:
I drove home and no bad noise. Same road (opposite direction)...warmed up. Same gear. Save revs.....weird.
No extra stuff in the car, just me. Same clothing. Same radio state (off).
Ideas?
BTW, no engine lights so per my service person, not misfires/pings.

I had the same issue, took a while to diagnose, but it was a defective heater core inside the dashboard. Hot water injecting thru the heater core causes the noise at high rpm. Have them replace it.
