    Hello,

    We have a problem to start the Audi A6 C7 after a crash, the impact was harmless but unfortunate because the sensor under the fender went off, activated the cushions and belts, so the pyrotechnic clamp fired, the car went out and did not start. After replacing the clamp, the car turns 1-2 times and does not start, there are many errors in the computer, no ABS communication and ubiquitous related errors. Air conditioning, etc. not working.

    What does not allow us to sleep is the inability to start the car, no communication with ABS and inactive air conditioning, for example, heating and ventilation of the seats works. Probably a lot of things will come to life when he blows his heart.

    Any suggestions ?

    Preliminary plan:
    -check the fuse and relay from ABS, as is known from ABS, various wonders can happen

    I have VCDS 17.8, but it doesn't define most of the errors in the computer:

    This is how the left beam, which goes to the bumper, is broken, the airbag sensor, the temperature sensor and the left sensor, for the engine cover closure, but the ABS cables are in the same bundle, but this section has remained intact.

    Maybe something from immo? However, here the engine would probably rotate for more than 1-2 revolutions, once I forgot to put immo pips in the remote control in another car and it turned but did not start, unless it is otherwise implemented in Audi.

    The worst thing is that vcds doesn't show error codes and I can't access another face at the moment.

    crash data fired from the airbag controller? Does any message pop up on the car's display when I try to start?

    I haven't kicked anything out yet, honestly it's the first time I'm dealing with such topics so you can say that I'm learning. A few bugs are mostly crap, the most important ones are a parking brake error and a brake system failure.

    There is no other error when you try to fire.

    I have to have some more comprehensive facebook to decode these errors

    Take the crash data out of the eggs and give the abs error number.

    Can vcds delete crash data?

    There is no carbon communication with the ABS Module

    Vcds can't clear a crash, a bit more sophisticated hardware is needed ;)

    Would you name the equipment that takes over? He will look at what prices, maybe it will be cheaper than a visit of a specialist and learn something.

    With VCDS, you can remove the error of the airbag firing, at least in such a way that there are no errors in the controller or in the meter, confirmed on the GOLF MK7, Leon II and Octavia II

    The car started, today I covered the topic, the problem was in the abs bundle. The climate has come to life, in general most topics have normalized.

    However, I have further questions:

    1. should I replace the impact sensor under the fender, are they disposable or not?

    2. Does anyone know what the principle of their operation is?

    3. Can I safely connect the pyrotechnic fuse under the cartridge control, so far the plug from the cartridge control is disconnected?

    4.If I put on new pillows and belts, will nothing shoot again? I understand that it is all replaced on a disconnected battery.

    5. Is it possible to replace the pads first and then delete the crash data? Or the other way around?

    If you have an "ecu faulty" error or something like that, you won't delete it.

    1. I do not know, for the sake of the sake of peace I would mention.
    4. Nothing will work out, do it on a detached battery
    5. Replace the caves and then delete the error

    For example, carprog, but this exceeds the multiple of cleaning by a professional. Alternatively, disassemble the controller and clean the batch manually.

Topic summary

The discussion revolves around an Audi A6 C7 (2013) that fails to start after a minor crash, which triggered the airbag system and pyrotechnic clamp. The owner replaced the clamp but encountered multiple error codes, including no ABS communication and malfunctioning air conditioning. Suggestions include checking ABS fuses and relays, as well as extracting crash data from the airbag controller. The owner later resolved the starting issue by addressing a problem in the ABS wiring, which restored most functions. Further inquiries were made regarding the replacement of impact sensors, the safety of reconnecting pyrotechnic fuses, and the sequence of replacing airbags and clearing crash data.
