Question about N20 Timming Chain
Hello F30 Community, i would like to know your take on N20 Timming Chain
Im proud 3rd owner of last of BMW 3 2016 328I N20 it is US Spec but i live in Europe it have it just reach 172.000 Km , Most of time car is filled with 98 Octan E5 from this cheap gas station and i putt extra aditive into it, and if i have long trip i just filled it up with 100 Octan E5
As i'm aproaching time for Oil change wich usually i do it myself but i also wanted to do my Gear box oil changed (Last time was 90k km)so i asked my mechanic if i should replace my timming chain.
My mechanic bassicaly respond with : i looked in oil cap and chain looks great and Engine run smooth, no click noises, no missfire so there is no reason to changed it.
But i had this problem that happened to me 4 times in past 1.5 year wich i couldnt get a right answear to it, some time i put like this cheap 95 Octan E10 gas from 1 gas station near my house like 20 euro only and when my car showed 30km remain for trip suddendly car just went into limb mode and lost power and tell me to stop. If i turned car off and turn on straight away it wont start like its trying to start but it wont so i turned car off for 2 minute and start it again then it turn on without problem.
Does this problem have something to do with my Timing chain that hadnt been changed yet? even if its not should i changed it yet? because its quite a hit to my budget to change a timing chain.
Thamks a head for any respond or suggestion.
