2013 A4 177 TDi Black Edittion Questions..

Good to have you on, I'll see if I can answer some questions. If I'm wrong I'm sure someone will soon be along to let me/you know.

The A4 has the mechanical version of Quattro versus the Haldex clutch system of the A3/TT so is always engaged. The split of power front to rear is the only thing that changes but I don't know the maximum splits off my head, I think that on a straigh, flat section of road it's supposed to be 40:60 bias to the rear.

A remap on these engines is seeing around 190-200bhp with a significant chunk extra torque I believe. From experience, if driven reasonably you can see better fuel economy than standard once a map is applied.

As for the poor fuel economy I can't comment as I've got a different engine. That said, I think that for the most part Audi seem to be rather 'optamistic' with their MPG figures to be honest...

No worries, hope it's all the truth!

I had the 170 in my 2010 A3 Quattro and the DIS averaged something like 42mpg if I remember correctly. Only had it for about 13k miles so I recon the engine was still getting into it's swing to be honest.
