I'm in the same boat with a non-performance pack GTI, also ordered in October but for delivery in late-Jan or February. This is the first I've seen of the engine being affected by the scandal, can you please post a link?
I am concerned because, with existing models, tax would not be affected. However in this instance the tax will be higher than I would have been expecting upon first registration, and now the worries about resale values apply to not only the diesel owners but the petrol ones too.
Any links before I get onto my dealer would be appreciated...!
