just wondering if anyone can help, I've had it diagnostics checked with three faults showing - mainly coms related but the one they apparently couldn't clear was a occupancy seat sensor which they are saying needs a complete replacement meaning the whole seat would need to Come out etc. This was caused by a water bottle being stuck under the front seat when it was moved forward, to that end I see it madness to replace a whole sensor when it could be basic wire damage. also I'm not sure the cost but I assume it will be high, anyone had this before or got any advice/wisdom they can give me on the situation.

many thanks!
