Hello dear Hyundai municipality, at our city flea the MkL lighted up recently without any obvious reason. Vehicle drove at this time quite normal. After that read out and there came the error P0638, thus an unplausible signal from the throttle valve bank1. Wanted to delete the error, but no chance. Error code comes again and again, but no indication of the MkL anymore. It went out independently after a few days and did not come again. Only the error remained and left The driver’s flap was not supposed to be changed immediately on suspicion, especially since the car is driving normally and without increased fuel consumption. Meister said that the vehicle had to run restlessly with this error and that a strong power loss should also be noticeable. Can’t explain why you can’t get the error out and at the same time the MkL doesn’t shine anymore. Maybe someone already had this F I don’t care, because the car doesn’t make any bitches, but with this mistake I don’t get any more Tüv. EZ 2016 1,2l 84PS 28tkm Thank you
