530li Four and a half years of maintenance and maintenance of 120,000 kilometers

8 18-6 The car has a mileage of 118,000 kilometers. I thought it would be necessary to maintain it when I was about 12.
In fact, I have never had any problems driving it normally. Many things have not been maintained. I just replaced four Michelin tire preventers three days ago. I thought I’d clean it up together and send it to BMW for specialized repair.
As a result, many problems were found:
The biggest problem is water leakage. Replace the turbine water pipe and the kettle. The water pump is not clear yet. Let me try replacing these two first.
The foot glue collapsed seriously, so two owls were replaced.
The brake pads on the front wheel are almost worn out, so they have to be replaced. The brake pads at the back are in good condition.
Spark plugs are replaced every 2- 3w in the forum. This car seems to have never been replaced. There is a little carbon deposition, and one of them is a little leaking oil, so all of them have been replaced.
I don’t want to make a fuss even if I leak oil, just glue it and seal it!
Clean up carbon deposits in the combustion chamber and intake air.
Transmission oil and oil pan replacement.
Cleaning air conditioning pipes + replacing air conditioning filter elements.
I spent a total of 7500 yuan, and my liver ached…
