Oddly enough, however, when I set the digital cruise control, it
doesn't quite agree with the more accurate analogue speedo. In other
words, if I want to do exactly 50mph through motorway road works, a
speedo reading slightly above 50mph is OK, but I need to set the
digital cruise control to something like 55mph to achieve this
precisely (if the traffic is heavy, I don't bother, and just let the
adaptive cruise control keep my speed the same as the cars I'm
following).

When I reach the end of the road works, (if necessary) I change the
target speed on the cruise control to, say, 77 mph to ensure that I
do exactly 70 mph. Again, the ACC slows me down if needed.


That sounds more like 10% over rather than 5%. Please explain?

Yes, the adaptive cruise control needs to be set approximately 10% over
the targeted true speed for some reason. The analogue speedo then shows
a speed about 5% over the true speed. It was a bit disconcerting at
first, but I soon got used to it, and haven't bothered to raise it with
the garage as I doubt that they'd know what I was talking about.


I'm not sure I know either, but as long as it works ...

There's a real problem with garage staff being way behind the
technology curve. It's a bit like the NHS where, all too often, the
only way to get proper treatment is to learn about your condition and
research it yourself.

My partner's Octavia has had chronic gearbox/clutch problems since we
bought it last April. After a new gearbox and five further visits,
the problem still wasn't solved. Following a few Google searches and
asking questions on a Skoda forum, it took a change of dealer to one
that services Skoda, VW and Audi (and therefore has a greater range of
experience of these mechanically identical brands) to identify and
quickly solve a problem with the dual mass flywheel.

The most senior mechanic at the previous dealer has achieved "master
Technician" status, which is apparently the highest level of Skoda's
technical qualifications, yet he didn't even know what a dual mass
flywheel was, nor how it could go wrong (and did).

Now I have learned about the vagaries of dual mass flywheels, that
Octavia is the last manual gearbox car we will ever buy. ;-)
