So - I got a phone call with an update today. S5's are open for ordering again - that's official - apparantley! However:
1. It appears the Co2 emissions and fuel consumption remains unchanged, but given this was being retested, neither I, nor the dealer is convinced this has been updated, and the computer systems / databases / info may still be updating so we should know more in a day or two.
2. Some of the specs / options may be changing / being added / being removed (including - I'm told the rotor alloys no longer being available) but they are still on the configurator . . . so again this (along with other specs / options) may get updated in a day or two.
3. It looks like the S5 I ordered in mid July, by the time the configurator / specs get sorted and the order back in, and Audi's backlog sorted . . . I'm likely to take delivery in March. Yes: March (I'm assuming they meant next year and not 2019)! Although that's t.b.c. - should know more in a day or two.
So there we go - news that's not really news, but that's the update I got from the dealer who by their own admission are as confused too, but orders of S5's are open again and no longer suspended.
I guess we'll wait a couple of days for the dust to settle and re-appraise.
March though . . . could be all sorts of other options / cars / models to consider by then . . . ??
