Hello, have a S40II with the following problem: Tacho failure, error message SRS Airbag maintenance urgent; you can only continue driving if you turn off the engine it starts again after several attempts. Can take up to 15 minutes. But also that the message appears only for a short time. If this error already had about 6-7 months ago, new software was played on it->was ok until now, but now starts again. Found a link with a video of the error.http://w ww.youtube.com/watch?feature=player_embedded&v=AwGeEqbmQ6c Auto was already in workshop, but nothing was found–> Error doesn’t always occur (sometimes it’s months of rest, then again everyday of the mistakes) Maybe who can help me from you ?
