This car is purchased for a new big trade, and the price is expensive. Generally, we rarely come to a small shop like me, and even if we look down on the stalls of these poor repair motorcycles, they all like to go to the 4S shop to maintain and repair. , The owner will not let the disassembly, afraid of the damage, I can’t cry and laugh, and I won’t let it move. What do you pull over? I can only use my eyes to watch the car?

In desperation, do I say that my shop plus a house is enough for you to this BMW car? If you can’t repair it well, you can buy you a new one. The owner is relieved, and the operation begins …

From Jane to annoyance gradually decompose, the owner watched my disassembly while helping me take pictures.

I have gone through 16 spring and autumn in this industry. I have encountered any kinds of customers. The soreness and pain inside know that it is clear that it can be conquered. No matter how high the technology is, it is empty. car!

After conquering the user, I started to remember my thoughts and put the line into my mind …

The BMW line has a reasonable layout, and almost every signal plug is waterproof.

There is no BMW route map in my hand. I learned from the car owner that I ride normally in the morning. After stopping, I did not get angry after starting, and then I couldn’t start with a car drag.

Based on the analysis of maintenance experience for so many years, I judged that this may be caused by three reasons: one is that the battery power is not enough, the other is poor line contact, and the third is that there is a problem with the starter or relay.

After measuring the battery voltage, you can reach 12.8V. The voltage is sufficient to exclude the first case.

Open the key instrument to self -check normally, the oil pump has a “tap” sound, the initial oil pressure is normal, and the motion boot button has no response.

The launching line of this car is similar to the car. It uses negative electrodes to form a circuit. The universal meter test does not turn on the machine. There are counting in the heart, and the fault is basically concluded in this area.

After some disassembly and detection, the root cause was found. For its reasons, the adverse lines of the negative lines caused the motivation to form a circuit.

Carefully polish, change the screw after re -reinstatement, and get out of touch.

Complete assembly.

It is not worth mentioning after finding the root cause of the failure, and you don’t even need to change it, but how to find it requires experience and technology. That’s how I repair the car, how about you?
