Well, I might have had a bit of a bombshell dropped on me today. I'm still in Germany on business and got a call today from Lisa at VW Customer services (I know a few of you have dealt with her), who told me that after all the promises that my configuration was valid, they now have had it confirmed that lane assist cannot be specified and it was a glitch that allowed it through.
She went on to say that it would have to obviously be removed (no real hardship there), but when I said, hang on a mo, would this be treated as a "change" to the order (which it isn't from my point of view), she said probably, and when I further asked if this "change" would have a build week implication, she couldn't 100% hand on heart, say no. So it could be that their system allowed me to configure a car in error, but I might be punished as a result

She's supposed to be calling me back on Tuesday with more information on my car, but to be honest (and with all respect to Lisa - she has after all always called me back when she promised), I don't hold out more hope of getting any more information. It going to be a case of it could arrive anytime between July and December, but we'll give you a call when it turns up at the dealers.
How on earth have things got this bad....what a shambles......
