So what do people think of fitting a particulate filter to a 2007 mk 5 2.0TDI? Would it be expensive and reduce any power? I love the smoke but i wouldn't want too much of it.| Candy White 2007, Mk 5 Golf, 2.0 TDI | 103 kw chipped to 138 kw | 19" Mercedes C6319 Gloss Black | Stage 1 APR Cold Air Intake | DNS-810 GPS Unit (Eventually...) | Diesel Geek Short Shifter |

Don't do it!!!!!!
DPF is a restriction. If your cars does not have one why put it on!!!
Spend you money on a ecu tune and do a mufllerectomy.
With a good tune you will get power and can get a cleaner exhaust if you like\( O ) o\====(\X/)=TDI=/o ( O )/ 2011 Jetta Mk5 125TDI - Squidly

The diesel particulate filter (DPF) alone will set you back around $3500 from the dealer (though probably cheaper if purchased overseas), and that's before you consider other miscellaneous parts and labour (installation and configuration) costs, and that's before you find anyone with the knowledge (or is even willing) to retrofit one onto a VW Golf in Australia... or any passenger car... in Australia.
Not to mention that a DPF has a finite service life (approx. 160 000 km, give or take 40 000 km depending on the engine, DPF and driving patterns) which current owners of DPF-fitted cars are dreading due to the cost of either cleaning it (through disassembly) or just replacing it ($$$), but that doesn't matter since you can dip into the savings from all the petrol you didn't burn by having chosen a diesel-powered car in the first place.
Other than that, it's not a bad idea.

There are so many people who would love to donate their DPF to you () but without the proper support in the ECU to regenerate it, it would quickly clog unless you drove flat out or on highways all the time.
I'm surprised by how little my car soots on track days but around town, it can dump a pretty dark cloud when I floor it from low rpm and let it rev out, especially if I've been in hypermile mode for a while, so that the exhaust flow is low and soot build up in the system.
My favorite was when I dumped on a guy double-parked on a busy road so that his wife could load her shopping(a tail-gating Golf R was my second favorite)

Soot is a waste of fuel, and shows you have inadequate airflow. Gale Banks, THE diesel guy in the USA is correct that soot is unnecessary on all but full out drag diesels, and if your car is sooting, you need more air. All the twin cams, multi-valves, tumble flaps, swirl patterns, piston design, injection pressures and ever increasing turbo flow is all designed to make the most of the fuel, and avoid soot, which is an incomplete burn.
To keep soot down, get a proper tune, from a diesel specialist. Anyone can ramp in extra fuel, but can they then get it optimised, to avoid waste and thus soot?? Make sure your air intake and exhaust are free flowing, and if needed go for a better turbo, but that's the last thing to do, and a major mod.
Diesels should only soot a little on acceleration whilst the turbo is off boost. If it's sooting on boost, your tune is too rich, and you are just wasting fuel. Soot all the time does not equal power, it just says you don't have an optimal tune, and yes that is how they come from the factory - not optimal!2014 Skoda Yeti TDI Outdoor 4x4 | Audi Q3 CFGC repower | Darkside tune and Race Cams | Darkside dump pDPF | Wagner Comp IC | Snow Water Meth | Bilstein B6 H&R springs | Rays Homura 2x7 18 x 8" 255 Potenza Sports | Golf R subframe | Superpro sways and bushings | 034 engine mounts | MK6 GTI brakes |

Maybe my Viezu tunes (all three of them) need some adjustment....

Alright thanks for some great info. I haven't had time to research before i question so excuse the remark about the particulate filter.| Candy White 2007, Mk 5 Golf, 2.0 TDI | 103 kw chipped to 138 kw | 19" Mercedes C6319 Gloss Black | Stage 1 APR Cold Air Intake | DNS-810 GPS Unit (Eventually...) | Diesel Geek Short Shifter |

One of my tunes is the 'Economy' map but it was created well before the Blue Optimize thing came out. It still out performs the stock map quite noticeably but rolls off much earlier than the other maps I have. And it still soots if nailed at lowish rpm.Resident grumpy old fart
