Quick question, I have been looking at the differences between different A4 1.8T models and I can't nail down the difference between the 2001 and the 2001.5. This is the model with the red flag on the side of the 1.8T badge on the trunk, is it just the K03 sport turbo? Is it worth looking for this model if I wanted a 2001 or is either model good. I have pretty much come down to the 2001 1.8T quattro because of the side curtain air bags but I would like to know the differences between the 2001 and 2001.5.

Thanks for any input.

 

I think that the red strip beside the 1.8T indicates 170 hp as opposed to 150.So on that note 2001.5!
