Re: bas/esp light
Just put in a new relay control module in my '04 coupe. It cleared the P0410 fault code (air injection system) but now the BAS/ESP lamp is on. I disconnected the battery to install the RCM, so that may indicate the BAS/ESP lamp activation is somehow related to voltage. Haven't driven the car yet to see what happens. My battery is relatively new and checks out fine. It's also maintained on a Battery Tender due to infrequent driving. All these advanced electronic systems can by annoying.
