Instrument panel lighting

I have recently changed my vehicle from a 2009 VW Touran to a 2017 VW Caravelle.  On the Touran, the panel lighting came on when the sidelights were switched on.  But on the Caravelle this doesn't happen until the headlight are switched on.  Initially I thought this meant a fault in the system but, going onto the Caravelle and California Owners Club website, I found that this was a VW feature and there were several adverse comments about it.   One poster pointed out that on a dull day, although lights were not required, the instrument panel could be in shadow and not readily readable.  Had its lighting been linked to the sidelights, simply switching just them on would solve the problem.  I know that switching on dipped beam would also solve the problem, but the jury seems to still be out as to whether headlights should be used during daylight hours, and I thought that the DRL's, which automatically illuminate when the ignition is switched on, were supposed to be the answer to this.  Another poster claims to have found that a code can be changed so that the instrument panel is lit all the time - presumably when the ignition is turned on. Another owner, along with myself, decided not to "tamper" in case of messing up something else. When the car goes in for its annual service I will be asking for this to be changed if it is in fact possible.
