Re: Can't decide between TDI and TFSI... help? –

My brother (lives in California) has the A6 Tfsi 3.0. He had an S4 prior to that and it's basically the same engine EXCEPT in the US they fit the ZF 8 speed tiptronic box to the A6 rather than the s-Tronic which they use in Europe. It's great car - very fast (as fast as my BiTdi but with more 'immediate' power delivery). He's done 30k miles (50k km) with no issues.
Now the S4 which was s-Tronic DID have gearbox issues... just lumpy changes and actually had a bunch of work done by Audi US (mechatronic changes, I think they may have even changed the gearbox). It never failed in any way but was a worry.
The gearbox would be my biggest concern... Fuel consumption, well despite JSRed's experience people with 245 / 272 and BiTdis generally get MUCH better economy than he is reporting. Usually up in the mid-high 30 MPG on average (my allroad averages 36 - 37MPG overall). Of course it depends on driving style and type of journeys that you make. The petrol V6 is not going to achieve that but it does seem reasonably economical particularly on motorway runs. I cannot give you specific figures from my brothers car (I could ask him if you are really interested) but I know he is impressed with the economy compared to his old S4. I suspect he is getting high 20s MPG on average. Having said that if you've done 200k km in your existing car then you're going to feel a 20 - 30% increase in fuel costs.
If you can get the Tfsi with an extended warranty (especially covering the gearbox) and you can deal with higher fuel bills then I'd say "go for it" - it's probably what I would do. No DPF to worry about.... no Adblue
