Last week for some reason the ECU started beeping after turning off the ignition. There is an aproximate 3 second delay after shutting off the car and then the ECU gives 5 short beeps. I've not made any modifications to the Loyale. I'm the original owner and it has only 107k on the clock, mostly highway. I'm still getting 26-32mpg combined and she runs like a champ. I've yet to check the ECU for any code, but I also don't want to do any harm by not immeditely addressing a potential issue. Any thoughts/suggestions?
Thanks in advance,
