big thanks to paul at wortec for sorting my fault code,engine light on my C7, common code P26C8, relates to changing your exhaust, i have a billy bullet,no actuator valves, after 3 years plus the ecu/bcm works out they are not in place so throws up fault code, heads up,im gonna save all you C7 owners £100 now, its not in the ECU, its in the BCM, it costs £100 ECU license fee to plug inTo your diagnostic, only the HP2 SUITE ,can delete this,anybody can switch it off but i can gaurantee it will return,i had to pay £200 as wortec initially found it in the ECU but 1 mile up the road it pinged back on,its a bit like crash data,eventually after getting into BCM its gone for good,even the importers ian allen cannot do this as they dont have the HP SUITE, WORTEC are near havant, portsmouth,total cost was £280 but should be £180 and you send me £50 for the freeadvice

yes the actuators in the original exhaust system,it relates more to aftermarket exhausts like billy bullet,borla,akroprovic that have no actuators and the setting in the infotainment screen is disabled
