ok so i now am on Firm V18 but on this firmware i'm getting this stupid drivetrain malfunction fault when I start up. Then i have to turn off the car then turn it back on and it goes away. (123412 electronic wastegate stop learning:stop position (wastegate closed) not found--123401 wastegate learning stop during *** heading cycle---123511 wastegate flap sluggish --- 123512 electric wastegate, wastegate valve coldstart: stiff. I had something like this show up before on the old firmware but i could overcome it by putting the car in accessory mode before starting. im not sure if that works now..... anyway i did 2 map 5 third gear pulls. first one i had to come off early. second one seemed pretty good. Any suggestions? should i stlll mess with the FOL?
