Non DPF A4/5/6
Discussion
Just for reassurance theres a lot of hype talked about DPF's and yes if they go wrong they can be expensive to fix, however, they are not as chocolate as made out to be.
If the car was designed for DPF then they are generally better eg 3.0TDI 08>, if they were added to meet regs ie 2.0TDI <07 they can be more problematic.
I also had this worry as my commute is quite short & engine does not heat up fully or allow sufficient revs with auto box. In over a year in these daily conditions the DPF warning light (pre warning) has never activated. When it does it gives an opportunity to clear it by driving with sufficient revs eg sport mode >2500 revs for 20 mins.
I try to give mine a hard run weekly/fortnightly & no problems to date. If you do regular longer journeys there shouldn't be any problems in theory. Most new Audis have them post 2006 so you are restricted sans DPF.
Personally i would have preferred a petrol manual but A6's are mainly diesel tiptronics. Just drive them hard on occassion to prevent them getting blocked.

sounds dangerous...

Don't forget diesel particulates are one of the most cancer causing substances known to man. Do you really want to be specifically looking for a non DPF car?
Dont forget that DPF car still release the same if not greater amounts of the nano particles which are drawn deep into the lungs and present the most significant risk to health. If you really care about the health implications of driving a diesel you just wouldnt and you'd buy a petrol instead. Dr G said:
The old PD diesels are more troublesome than a modern DPF by a long way.
If you are talking 2.0TDI PD's then yes they are not as good as the CR engines, but pd 1.9TDI lumps have been around a while and are pretty damn reliableEdited by chris285 on Friday 12th December 13:12
As mentioned, they aren't as bad as they are made out to be, I do mainly town miles where the engine doesn't always reach temperature.
I bought my 2008 A4 in Aug 11 with 96k on it, it now has 130k on and I have never seen the DPF light once. I know it's still fitted as the exhaust smoke is almost clear (not thick black) and I sometimes have the fans running when stopping.
I do make a habit of trying to go on the motorway at least once a month for a run with it in mind, although don't do it religiously, maybe I've just been lucky?
