Yes its me again LOL, from one thing to the next, Trying to make this car perfect and 100% code free. I've got a rear air suspension code U1026 Invalid or missing data for engine RPM. its a pending code and doesn't set a light and the suspension works fine, just wondering if anyone else has encountered this, cant find anything on the codes diag procedures. Honestly if I dont figure it out I dont care, it doesn't affect functionality or set a light. Thanks
