Hello, I bought a Volvo C70 convertible built in 2002 a good two weeks ago, which stood for some time. My plan was to make the convertible so far fit for the TÜV, which has worked well so far, the last lack which prevents me from driving over TÜV, but the SRS lamp is causing some problems. My workshop told me that it could not read out the ECU (I am unfortunately not familiar with which device it was tried) , then I got a cheap reading buys (the iCarsoft i906), which also worked very well with my 1997 V70 before. But this too could not read out the airbaig error. Could it possibly be related to my car and not at all to the readers? And how would you proceed now? I am grateful for any help.
