This BMW 5 Series is my first car and the one that has been with me for the longest time. It is now 100,000 kilometers and I need to do a major maintenance. This time, I still choose BMW Changyue Maintenance. This is BMW’s original factory maintenance. I think whether it is a major maintenance or a minor basic maintenance, I still have to go to the 4s shop for the original factory maintenance.

Because any small accessories used in the 4s shop are original factory, the quality is better than the accessories used in outside repair shops, and the technicians in the 4s shop have better skills and are all professionally trained. Every maintenance work they do is recorded, and even if there is a problem, it can be traced back to it. Unlike outside repair shops, where there is a problem, no one can find it. So it has to be more reliable to maintain it in a 4s store.

This time it is major maintenance, oil triple filter maintenance, brake fluid maintenance, engine carbon deposit cleaning, engine water leakage (replacing auxiliary water pipe, exhaust pipe, upper water pipe, antifreeze), engine oil leakage (replacing valve chamber cover assembly, engine oil pan, main oil passage sealing ring), mainly these.
