Hey @Sweetface, did you find any guide to change that solenoid out? I am having the exact same issue with the exact same codes and am pretty sure that VVT solenoid is my issue. I'm sure I can swing the fix but a little guidance wouldn't hurt.
Looking for a new set of wheels and tires to replace my PP1's on my S550. Would prefer something staggered but if its square, at least 10 in wide would also work. I am in Central WA and am willing to drive to meet up.
