On the new models the 140 has a single tail pipe where as the 170 has a twin.
170 definitely + a remap your looking 220-240bhp.
How did you deal with your DPF mate or have you not remapped yours yet?

I haven't had mine done Yet. You have a DPF delete when getting a remap on DPF engines unless you only want upto 200bhp.
I'm going to wait a while or ill get bored of having the power, want more but have to folk out big money for the next step.
My 2.0 TDI-140 has been remapped to around 170. It was done over two years ago and I have had no problems at all with the DPF. The problem with removing the DPF is that I'm sure sometime in the not too distant future a diesel car will need a DPF to meet the emission standards as they are gradually changed and a car that had a DPF when it was manufactured and has subsequently had it removed will fail an MOT. It is already unlikely that a petrol engined car that has has it's catalytic converter removed will the the MOT emission tests.
I was going to get mine mapped and bin the dpf but i now have an injector issue and manifold intake runner control (basically the throttle body) has jammed open so the car is doing 28 mpg at the moment which is less than the mapped vxr i had so i think i will be sorting these issues out and selling it instead.
If i had known now when buying i would have bought a 140 and mapped it, the 170 has been nothing but hassle and the dpf plays up all the time and the mpg is pretty poor, i think at max i have had 45 mpg where as a fellow work mate gets on average 45 with long journeys he gets 55mpg and thats a 140.
As for the DPF doing its job, I have had mates following me and didn't believe it was a diesel as there was no smoke or smell even under hard acceleration. Definitely does its job but will definitely be coming off if they pass 2012's mot without
Depending on the age, but from 2009 onwards both 140s and 170s are fitted with a DPF. Prior to my current car I had a 2007 2.0 TDI-170 and had no problems at all with the DPF on that either. In fact I never even say the DPF light come on.
I am just about to order another A3 because mine will be 3 years old in April and I tend to change my car every three years and there is a 4-5 month wait on a new one. The new 2012 A3 will be released some time next year but only in 3-door version. The Sportback is not due until 2013 and I like the existing one anyway. This time because of the problems related to remapping the latest ECUs - it can no longer be done through the diagnostic socket and the ECU has to be removed from the car - and the fact that with the 2012 MOT a car can be failed if it has obviously been remapped beyond the OEM specifications and also the insurance for a remapped car I think I will be going for a 170 again.
After all the DPF is there for a reason, to help to protect the environment and the people living in it. This may come low on some peoples list of priorities but it's quite important to me. After all Audi have spent a lot of money making their cars more environmentally friendly it does seem a bit silly for owners to try and turn the clock back.
I'm worried about the Germany laws tbh. Planning on going there a few times a year. Reason I wanted it removed was for the custom code remap which requires the dpf to be removed to get its full potential. Is there a thread out the emissions law in Germany? I'd like to know what it entails.
I test drove a mapped quattro which had had the dpf removed and it was quick but it smoke more than an old bus to the point the cockpit filled up with smoke on start up with the door open so i didnt buy it.

I drove both the 140 and the 170 and decided I couldn't live without the extra power of the 170 (had a remapped 130 TDI Golf before)
Mine's now running the following with the DPF still in place
Who did the remap mate? and have you noticed a improvment in MPG.
I have a 2009 2.0 TDI 140 common-rail engined Sportback and mine had twin exhaust pipes. Speaking to an Audi Master Tech a year or so ago he said that the only difference between the current 140 CR and the 170 CR engines was the size of turbo used.
