Gunnut Posted February 2, 2017 Report Share Posted February 2, 2017 Further to my last thread " Have I done a wrong-un " took the Tiguan in to my local garage for a oil & filter change and asked him about the lights that were showing up on the dash....POO88...P2463...P2463P went and collected that afternoon, no problems but best to take it too the main Stealer for the codes to be read. His advice was modern diesels don't like short journeys, if I were you I would give it a good thrashing for 15 minutes or so to clean the Particulature filter out, something I new already, but being in my 70s I wasn't to keen to do on a regular basis.So off to the VW people for some more advice, after driving 20 miles too some swanky high-tec showroom, the said they could read the codes and can regenerate the DPF but this could happen again within weeks because...Wait for it The modern diesel engines do not like short journeys, you best bet would be to drive it at 2000/2500 revs for 15 minutes or so to clean the DPF out. Another 20 mile trip home, then I thought to myself, why after a round trip of 40 miles was that bloody light still on. Walked round to my local Ford stealer he said codes no problem DPF regeneration £95 going in this Monday, watch this space. Quote Link to comment Share on other sites More sharing options...
HDAV Posted February 2, 2017 Report Share Posted February 2, 2017 (edited) Check but the regen is basically using the computer to run engine at high rpm while not moving..... much better doing it yourself second gear dual carriageway don't change up ..... (take ear plugs) at least that way you only spend the fuel which your spending anyway with dealer ...... Unless you drive the 20miles home at 4K rpm you didn't do anything but drive 20 miles..... what the ford dealer didnt say was we'll charge £95 and the light will probably come back on in a few weeks..... you know the rest...

Medic1281 Posted February 2, 2017 Report Share Posted February 2, 2017 It's almost like you were mis sold a vehicle that doesn't suit your needs. Did you buy it from a dealer? Quote Link to comment Share on other sites More sharing options...
Rupert Posted February 2, 2017 Report Share Posted February 2, 2017 I had this on my VW after a couple of weeks of short trips, i ran up the motorway for 1 junction about 5 miles at 70 on cruise but one gear lower so revs were elevated.

gustaff Posted February 2, 2017 Report Share Posted February 2, 2017 the vehicle cannot regenerate dpf with fault codes logged in control unit forced regen via diagnostics only solution but car will keep blocking up with short journeys Quote Link to comment Share on other sites More sharing options...
four-wheel-drive Posted February 7, 2017 Report Share Posted February 7, 2017 I have to say when I got my 2.8 deisel jeep I thought that I was doing good but the more that I think about it I wish that I could have found a good 3.7 V6 petrol one not that much difference in fuel consumption as most of my trips out are not that fare and I do miss the smooth running of a nice six cylinder petrol engine but it is done now so I will have to live with it.

MITCHF Posted February 9, 2017 Report Share Posted February 9, 2017 Remove the dpf get a re-map, no more problems Quote Link to comment Share on other sites More sharing options...
Jason_ox Posted February 9, 2017 Report Share Posted February 9, 2017 I wouldn't suggest removing the dpf and remap etc. I've just sold my 3litre BMW diesel because it was never used and I don't like the way the government and manufacturers are backtracking on the diesels. I never had a dpf problem because when I did use the car it was mainly motorway use. With regards to the above, if it has fault codes it will probably not regenerate is true. Also I see people go on about driving in 4th gear at 70 to get it to regenerate, it's just not true. All the correct parameters need to be met to regenerate it's what's called a passive regeneration and having fault codes stored or a current fault it will not let you. Forced regeneration is ok done by a competent person but again generally certain parameters need to be correct and not off the scale to do this, otherwise its a new dpf.

norfolk dumpling Posted February 9, 2017 Report Share Posted February 9, 2017 Wife has a 1.6 diesel mini and no such problems having now done 30k. It does however sit and run itself at 3k revs for a few minutes every few weeks. This happens as you come to a standstill and we are told it is self-cleaning. Otherwise no issues at all with car although we are 10 miles out of Norwich and nearly all our trips are 25 miles plus. Quote Link to comment Share on other sites More sharing options...

Cannon Posted February 9, 2017 Report Share Posted February 9, 2017 The new MOT legislation will catch out anyone who has had their DPF removed. This will be an automatic MOT failure, which means an expensive bill for a new DPF and software update. Revving the life out of the engine will not improve the chances of regeneration. The engine management software adds additional fuel or catalyst as and when needed. A heavy right foot could slow down or prevent the regeneration. There are aftermarket DPF cleaners out there that do work, but they will never get the DPF like new. One other thing to mention is that a lot of garages (including main dealers) automatically assume the DPF is clogged and causing the problem. The pressure sensors used in DPFs are like any other vehicle sensor. They can and do fail, just like oxygen sensors or crankshaft sensors etc. Most garages will authorise DPF regenerations based on assumptions, but they won't actually bother to go through the proper diagnostic processes required to determine the exact cause of the fault.
