Since April 20 12, Mr. Chang has been asking the 4S store and BMW's headquarters in China for explanations. Up to now, the problems have not been solved, and the road to safeguarding rights is extremely difficult. According to my own calculation, the actual oil consumption of 1000 km has reached nearly 1 liter. Mr. Chang only knew after consulting automobile professionals that excessive combustion of engine oil may damage the engine and even endanger driving safety.
BMW's official maintenance manual indicates that the maximum allowable fuel consumption of BMW gasoline engine is 0.7 liters per thousand kilometers. It is pointed out that the measurement of fuel consumption needs to strictly follow the professional operation process, and only authorized dealers of BMW or institutions with corresponding testing qualifications can provide effective measurement results.
Mr. Chang measured it himself, and the fuel consumption per thousand kilometers of his car reached one liter, which exceeded the limit officially announced by BMW, so he found BMW's Jinqibao 4S store in Yulin. However, the test results of this 4S shop show that the fuel consumption of his car is only 0.2387 liters per thousand kilometers.
The test results of BMW Yulin Jinqibao 4S store are more than four times different from their own measurement results, which makes Mr. Chang feel very abnormal. Later, he went to BMW Xi Anrongbao 4S store and tested the fuel consumption again. Results The test result given by Xi Anrongbao 4S store was 0.65 liters per thousand kilometers.
It is very close to the upper limit of 0.7 liters of oil per thousand kilometers in the BMW maintenance manual. The test results of the two 4S stores are far from each other. Mr. Chang thought that the data measured by the 4S shop was suspicious and suspected of fraud, so he began to report the problem to BMW China. However, the customer service staff of BMW China said that it is normal as long as the fuel consumption per thousand kilometers is within the range of 0.7 liters.
Extended data:
According to BMW's maintenance manual, the oil needs to be replaced and maintained for 10,000 kilometers. According to the calculation, the engine needs 6.5 liters of engine oil (running 1 10,000 kilometers), but now the engine only adds 4.25 liters of engine oil, which means that my engine does not need engine oil for the remaining 3,000 kilometers, but runs with zero oil.
According to the test results of 4S shop, Mr. Chang's car can't wait for the maintenance period of 1 10,000 kilometers at all, and the oil has been burned out. Driving without oil will inevitably seriously damage the engine. Therefore, Mr. Chang repeatedly asked Xi 'an and Yulin BMW 4S stores to solve the problem and complained to the industrial and commercial department, but all failed.
The problem of burning engine oil has not been solved. A trip in April 20 12 put Mr. Chang through a life-and-death test. The engine suddenly turned off while the vehicle was driving, which made Chang still feel scared.
Phoenix. Com-CCTV: BMW's burning of engine oil led to flameout, and the owner's rights protection was beaten.
