I had the same issue which showed drivetrain failure intermittently then it took it to limp mode it had ran 63k. After speaking with several garage and they pointed out the same issue. It was due to timing chain being stretched. i changed this which costed me near to ÂŁ1500. This included new camshaft sensors, timechain replacement, spark plugs and servicing. It has been running smooth since.
