Although I'm frequently on the Opinions and 740 forum, as my V70 is a Tdi (I'm a Brit) I don't normally post here. However, this problem will be common to all V70's so I thought I'd ask you guys as well as the UK forum, as there may be limited experience of this proble, so here goes. I had a recurring SRS light keep coming on on my classic shape 2000 V70 which was reset a couple of times by the dealer (I don't have a code reader, the Tdi needs VCT tool). They told me it was a 412 code (each time) which indicates intermittent NSF SIPS airbag and said it would need replacing. This I agreed to, so they changed the bag in August. The SRS light came on AGAIN last week so, today, I've just had it checked again and, guess what, it's a 412 code AGAIN. Dealer insists that the airbag WAS faulty (but how they knew I can't imagine because the fault code always cleared indicating an intermittent fault) and are now suggesting the car needs to be left for a day to "check the SRS system". So, how specific is a code and, if it is not specific, how can they change a part that may not be the fault. Do I have a case for claiming money back? (I've just paid them to clear the same code, suppose I should have refused payment). I realise US litigation / consumer rights are different but I'd value any opinions please. This car is beginning to get expensive. Regards.

I'm not sure if an SRS code tells exactly where the fault is. However, Volvo is no longer in the business of "fixing" things but instead of "replacing" things dependent on code. It's that way in the U.S., and I assume all over the world.

In our old 850 we kept getting an SRS code. Went through some airbag "tries" but the problem ended up with a mylar cable inside the steering wheel that spins with the wheel, winding and unwinding as you go. When that part was finally fixed all of our problems went away. Might be worth asking about this...most likely it's something like a connection to the airbag and not the airbag itself. Those hardly ever go bad.

Thanks. I have VADIS software and a 412 code IS specific to an intermittent NSF airbag (the seat one). So I presume the only cause, assuming the connections to the SRS controller are OK, would be a dry solder joint on the SRS circuit board going intermittent. Regards.
