Hello,

I would really use an advise from experienced people. I have been reading a lot and it gets me to worry so I wanted to ask if I should start spend some money to prevent engine disaster in the future. Car is on 190k Miles very high 315k (2011).

Up till now what I read that could cause disaster are (Hopefully this only as maybe not limited too, please mention more if you think ):

1- Waterpump + its Thermostat
2- Crankshaft Pullys
3- Serpentive Belt
4- Turbo something!!!

I do have service history of the car from BMW but I do not find any of this done there also seems that BMW and other mechanic wont do any preventive job, they just fix what it's broken. Usually normal service were done on car since day one.

However, do you really think I should start changing these right away? so far there are no sign of failures, as I see car is running fine and no noise or cracking or similar!!! I even video the sound as not sure if it's bad or normal however I do not want end up with a disaster while driving

One last thing, if I should change them, is it doable as DIY or you think I should go to mechanic (They will charge a lot for this I believe)

Any recommendation?

Regards
