Hi,
i note here that you are talking about the efficieny programme, assume you mean the option in drive select? I've posted elsewhere in this forum that I did have an efficiency option ( along with comfort, auto, dymanic and individual) but that it disappeared one day.. yup, just went on holiday leaving only 4 options. The dealer says it was never there but it was, that or I am mixing dreams with reality, because I recall using it often on drab motorway runs. The responses to the forum have yet to prove other S4 B8 drivers have it... just lots of helpful theories...

Any chance you can let me know if this is what you are referring to and if you indeed have all five options? Looks like yours is a 15 plate, so is mine, a UK black edition avant... so in theory if it's available on yours then I can show this thread to the dealer to prove I'm not losing it. Thanks, hope that ramble makes sense. All the best Alistair
