Long story short

car has rattling sound for few days on first start up; it rattled for a second and everything goes well until i park vehicle for more than 1-2hours

fast forward to today, the car suddenly has hesitation starting up and check engine light out

plugged in Xentry and found fault code

P001685 - the position of the intake camshaft (cylinder 1) is implausible relative to the position of the crankshaft....there is a signal above permissible value
Other than car has hesitation to start, its fire up with no misfire or whatsoever

Can someone tell me if i should be changing

timing chain guides etc or sprockets will do or is my camshaft gone?
Can anyone advised if this is common is M133 engine with 70k miles on my 2014 45?

Will appreciate if some gurus here (who gotten this before) will share their repair experience
