For what it's worth, after we'd left the runway and on the taxi to the gate, there sounded like there was something not quite right - it definitely wasn't the usual quiet A350 taxi that I'd heard in Madrid or on the outbound flight. I'd describe as a sort of shuddering/growling type sound. Not sure if it's significant. Didn't think too much of it at the time, but now I can't help but wonder if it's related to the plane going tech.
