Hello, please consult my Passat Yu Ling 2007 model 2. 0 manual, 5 years old, found that antifreeze is always leaking and engine oil is lacking for no reason.

Antifreeze: 1. Confirm whether there is leakage 2. Repair or replace the leak.

Engine oil: Volkswagen burns engine oil. It is recommended not to maintain it blindly, mostly piston rings. Check the consumption.

It is recommended to go to a professional repair shop or 4S shop for inspection. Under normal circumstances, the total repair cost is about 2000 yuan.
