Is this normal for a 5 years old car? I have a 2005 3.0 and I have replaced the 2nd air flow sensor 4 times. The last time I replaced it was about 10 months ago. Now my Service Engine Light is on again and the OBD CODE is P1419. Could there be something else wrong with my X5? Any help or advice will be greatly appreciate.
