Hi XRAD, maybe you have to control the connectors of the airbag for extra resistant. It seems strange that the first run to delete code had no succes after 10 seconds.
You have no options with durametric to look into airco, abs, alarm and tiptronic?
Maybe you can do some experiments to ad a code in the software from durametric? Doe they have a config file where you can manipulate the adresses from the different components in the car?
here you have an example
[S00] This is the mainadres!
and those are the faultcoades possible.
;Anti-lock/traction control trouble codes
11=Lateral lock valve-No feedback signal from valve to control unit
12=Lateral acceleration sensor short-circuit/break in circuit
13=Lateral acceleration sensor-implausible signal
14=Lateral lock-deviation in regulating values
15=Control unit defective
21=Front left speed sensor
22=Front right speed sensor
23=Rear right speed sensor
24=Rear left speed sensor
31=Front left ABS valve
32=Front right ABS valve
33=Rear axle ABS valve
34=Valve relay
35=Return pump
41=Front-rear differential lock valve
42=Front-rear acceleration sensor short-circuit/break in circuit
43=Longitudinal acceleration sensor-implausible signal
44=Front-rear differential lock control diviations
45=Full differetial locking button

;Climate control trouble codes
11=Inside temperature sensor
12=Left mixing chamber temperature sensor
13=Right mixing chamber temperature sensor
14=Evaporator temperature sensor
15=Rear fan temperature sensor
21=Oil cooler temperature sensor
22=Defrost flap motor
23=Footwell flap motor
24=Fresh air flap motor
31=Left mixing flap motor
32=Right mixing flap motor
33=Left heater blower motor
34=Right heater blower motor
41=Condenser blower motor

43=Rear blower motor speed 1
46=Rear blower motor speed 1
44=Rear blower motor speed 2
47=Rear blower motor speed 2
45=Inside sensor blower motor
I don't know if you are handy but others let me know. maybe I can help you out?
