Beavis Posted December 9, 2012 Share Posted December 9, 2012 I am considering a second hand one for my daily driver, but i am reading lots of meither with the pdf's on these cars if used mainly for local driving and short journeys. Anyone own one or have experience of either of these engines in the Golf or in other cars? For example Audi, Seat? Quote Link to comment Share on other sites More sharing options...
smudgedon Posted December 9, 2012 Share Posted December 9, 2012 (edited) You mean a dpf? Diesel particle filter The 170's get clogged up a lot with short journeys/town driving. Not a huge problem, just a design flaw The revs will then hold out longer to keep the exhaust temp up to burn off the crap in the dpf that's built up A motorway blast every now and then clears it out. Alternatively, a lot of tuning companies make dpf delete pipes which then requires a remap quite convenient really! My old 2.0tdi Audi A3 170 kept getting clogged. Just went for 10mile motorway journey once or twice a week to clear it Edited December 9, 2012 by smudgedon Quote Link to comment Share on other sites More sharing options...

smudgedon Posted December 9, 2012 Share Posted December 9, 2012 It's just a design flaw that VAG never really bothered to fix You can either live with a minor inconvenience and go for a nice blast every now and then or spend about 500quid to eradicate it all together and get some extra power and mpg too!

Voodoo Vix Posted December 10, 2012 Share Posted December 10, 2012 DPF's are a nightmare in general, don't think its just VWs, our 307 has had the dpf light flash up for the last 18 months, it'll probably be removed but unfortunately this will make it fail the MOT as decats do. It's the only thing that puts me off getting another diesel as a run around. Quote Link to comment Share on other sites More sharing options...
Chris`I Posted December 10, 2012 Share Posted December 10, 2012 All cars with DPF will suffer on short and stop/start journeys. Its because the gas flow and temp isnt held high enough for the carbon to burn off. Usually a light will come up and you need to go for a decent drive at 60-70MPH for it to clear. Be very weary of not doing this when it tells you as blockages will form that cant be cleared and you will kill the DPF. Saying all that, our Alfa has one and its been fine for the last 18 months, but we do a reasonable amount of higher speed driving. When we got the car the salesman did ask and recommended a small petrol unit if we were doing a lot of town and stop/start driving. What kind of driving are you doing Dave? If its a lot of stop/start/town driving, you may be better off with a small petrol, especially if petrol prices are like they are down here, its about 10p/litre less for petrol than Diesel!

spursmaddave Posted December 10, 2012 Share Posted December 10, 2012 My Leon PD170 has never had any major DPF problems but then it is a daily driver and gors on dual carriageways etc. It has only gone into regen twice in 65,000 miles and a quick blast sorted it both times no bother. Yes there have been problems but unless you only do 5 miles a day and never get over 2k revs then you will be fine, and if you do then why buy a diesel The 170 is VERY powerful, great fun for a derv but not the most economical The 140 can be tuned up fairly cheaply to 160 and is a fair bit more economical....

StevoD Posted December 10, 2012 Share Posted December 10, 2012 Used to spend 60% of my time at a Seat Dealer doing regenerations on DPF just do as the hand book says and make you sure you get them nice and hot youll be ok Quote Link to comment Share on other sites More sharing options...

What you really want is the 180 (bi-turbo) but you need a van or a Amarok to get that Quote Link to comment Share on other sites More sharing options...

StevoD Posted December 10, 2012 Share Posted December 10, 2012 if your going bi-turbo just man up and get 3.0 v6 or if you really wanna go for it get the v12 tdi Quote Link to comment Share on other sites More sharing options...

Main daily driver Chris, no stop/start driving for me on my way to work about 5 miles from home at 5.45am on a dual carriageway. Just love the torque and economy you get from a Diesel. :smile: Quote Link to comment Share on other sites More sharing options...
Stew Posted December 10, 2012 Share Posted December 10, 2012 My 'shed' is a 170. Haven't had it long enough to comment really though! Filled it up 300 miles ago and still have over half a tank though..... Quote Link to comment Share on other sites More sharing options...
Ricey Posted December 10, 2012 Share Posted December 10, 2012 V6 derv units actually sound very nice indeed. 170 VAG unit in my TT. Not fast enough but fast Woeful fuel economy (but ive got 4wd) unrefined noise out of mine but not sure about others......definitely verging on the 'van' noise side of things. Would definitely benefit from a remap. If i get a derv again it will be a v6. Quote Link to comment Share on other sites More sharing options...

Be very weary of not doing this when it tells you as blockages will form that cant be cleared and you will kill the DPF It's still working but does need replacing, it mainly does shorter journeys (apart from when my boyfriend comes to mine as its a 100 mile round trip) so it doesn't get to burn off much, if you accelerate hard then the light comes on but once you've been going a while it goes off again, but for doing almost 150k miles on the original one she's doing well!

kbeast35 Posted December 11, 2012 Share Posted December 11, 2012 Just been speaking to a friend who has a '06 golf 170tdi he tells me that the majority of mk5 140's did not have dpf's until the mk6 '08 onwards (if true may be the way to go for your short commute) He's also getting it performance mapped at Xmas for £700 this includes removing the internals of the dpf so from an mot perspective it's still fitted to the car and the map should keep the emissions down and the performance up Quote Link to comment Share on other sites More sharing options...
