BMW 520 528 530 728 740 750 X5 security data loss recovery without replacing any parts
First, the BMW EWS2, EWS3 anti-theft computer is most likely to cause a computer data loss is one of the main set of unreasonable failure to:
1, when the battery voltage below 9 volts, with a key three consecutive open the switches can not start the car the car, and then can no longer start the car.
2, the car is not enough external electric power supply charge, please do not start the car, start car battery clip easily lead to bad data. Ten minutes later and then start charging.
3, power door locks if the keys to the car will not start for a long time, the door slowly opened the door and light Always wear the battery voltage below 9 V is the most likely to cause data loss.
Many repair shops have encountered this problem, like to repair the key when inserted in the switches inside, the BMW anti-theft computer using EWS2 and EWS3 models, when the key
When inserted into the ignition switches to start communication on the code, if the voltage is lower than 9 volts, ESW security computer will recognize the legitimate key code key code lock is illegal not to
Work (commonly known as the hopping code). This situation must be replaced as general EWS computer to replace the EWS computer must be set to the 4S shop.
Key data loss can not start the car, most of the mechanic can not repair, previously used only by purchasing a full set of PC replacement, or a re-match
Ordinary PCF7935 chip modified the original remote control car to start the car, which damaged the original remote control keys with the charging function. EML electronic chip is very simple
Key code can not jump start the car has no need to replace the original car keys, chip, do not break open the shell of the original key, the key data can be read by AD90, by modifying the computer data can EWS3
Repair and maintain the original key charging the same.

Pirates of the computer has been damaged and must be replaced EWS computer rewrite data, you can buy a computer without having to replace the old new EWS.
Note: Check whether the work EWS3 computer, do not use the test with a small light bulb to test whether EWS3 plug harness the power of any, or
Very easy to burn EWS3 small computer inside the CPU, causing anti-theft system is not working properly
