نوشته شده توسط : Likaibin

Model:
Mercedes Benz SL500 (R129) 2001

Problem:
Made a key for a 2001 SL500, car ran fine for 2 days.. Then car won’t start..
Solution:

hht-win-benz-sl500-1

hht-win-benz-sl500-2

hht-win-benz-sl500-3

hht-win-benz-sl500-4
Took immo box out and read HC05 chip with xprog 5.84, data was garbled..
Tried writing data to two new/used immo boxes.. those were bad too..

hht-win-benz-sl500-5
hht-win-benz-sl500-6

Put Julie emulator on DME, a Bosch ME2.0, first try, the car started but no gas pedal, wrote data again and personalized DME, and it worked fine…

When checking DAS authorizations under actual values, make sure to hit the right arrow button, it shows the last authorization…

Procedure to personalize/code DME:

Device used:

MB Star diagnostic scanner SD Connect C4/C5 with software HHT-WIN (latest mb star software has HHT functionality)

Connect C5 Xentry Connect multiplexer via WLAN cable and setup software on my a Dell laptop
