Twice in the last week "Max engine rpm 6400" (or similar) has briefly flashed up on the MFD on engine start up. There hasn't been a flare of revs, size 12s no where near the accelerator. Yesterday it did it as we set off for a 200 mile journey fully loaded up for a week away. 

Also, ACC was disabled and so was stop start. 

After the long run, all seems fine now. 

Is this a symptom of a dieing battery? It's the original and I only normally do short runs.

Quite possibly, based on the stop/start being disabled. That was how my mate knew his Superb needed a new battery. The "max revs" thing may be another undocumented bug though.

It's been fine again today, shame that my OBDeleven is at home to check for any other faults.
