A family member has an A4 Avant and on startup when it's cold, if you try and accelerate when its stationary or moving slowly there is a massive lag before anything happens. It's hard to explain but it's definitely not the lag of a petrol engine without a turbo.
I did try and search the forum but couldn't find anything. Is this like anything that anyone has heard of? I've tried doing an accelerator reset thing which didn't work.
It's a 2010 A4 2.0TSI Automatic Quattro Avant. It's only done 10k.
