What's the context behind the search? Did the TTS come with a space saver and it has gone missing, or does it not have a spare at all?

Mercedes use the same pdc and centre bore, but I couldn't vouch for whether a Mercedes space saver would clear Audi brakes. Or indeed, whether a spare from a different model of Audi would clear TTS brakes if the TTS never came with a spare.

I have a C-class space saver in the workshop which came from my Dad's car when we swapped to a full size spare, but I think the tyre might be too small on that. I can check tomorrow.

Having owned three of them, I could not knock them.

Brilliant cars, all three evolutions, utterly reliable with way way better dealers than Audi, fun to drive, cheap to run. The last one, the JCW, would leave most cars trailing on a B road, including my M4

As for the so-called 'maxi' version, I could not believe how much better the fit and finish was on the 3rd gen car we had, compared to the gen 1 and gen 2 cars that preceeded it.

Dare I say, pishes all over an Audi A1

The TTS came with a tin of gummy stuff and compressed air (as did the mini) but no spare. It looks like it never had a spare of any kind and, although I’ve never used the gummy stuff and air, I’m sceptical, so would like a space saver if I could find one.
