Title: Golf TDI DPF
Post by: Sir Tigger KC on 26 October 2014, 13:58:04
My neighbour's '09 Golf 2.0 TDI has a blocked DPF and has been quoted £2000 by the dealer to replace!  :o

I see there are pattern ones available from ebay for £200-400 or secondhand for a similar price.  Is this a job that can be done on the driveway or would we need something like VAGcom to reset the electronics?  :-\

I've seen cleaning services advertised where you send your DPF off to be cleaned out.  Any thoughts on that?  ::)

Apart from why it's blocked up, I don't really know much about DPF's so any advice appreciated. Ta!  :y

Is it completely blocked and stopping the car running our had it just put the warning light on.  Not sure about a totally blocked dpf but if it is just the warning light a forced regeneration should sort it out. Can be done on a diagnostic machine or if the car will drive, by giving it a 10 mile run at constantly over 2000 rpm.

Not sure about the warning light to be honest.  He said it's been 'juddering' when cold and he's been told that's what the problem is by the dealer.  ::)  and the price!  ::)

He's gone away on a trip this weekend, I think to Lincolnshire or somewhere over that way, so it will get a good run.  :y  Maybe it'll sort itself out.  :-\  But it's generally used as a shopping car so no surprise if it's getting clogged.  ;)

Old derv drinkers could handle this arduous task without spitting the dummy. So why not new ones?

There is something very wrong with modern diesels if you ask me.

Its a cunning plan by the designers and manufactures to rape the average bloke in the streets arse wallet after the car is around 5 years old / 80,000 miles  >:(


Tiggs, if the car will start and run, give it a Italian tune up and rag the shit out of it down the motorway for as many miles as you can then see if its any better

EU emissions laws.
Modern cars with Dpf will run a regen cycle when the soot level rises, but to complete it the car needs a few miles. Of the revs drop the when cycle doesn't complete and the soot continues to build. Short troops don't let the soot burn off by itself an so the filter blocks up. It should put a warning light on the dash and if you ignore that it will put the car into limp mode.
I am all for cleaning up emissions, but dpf's and short trips just don't work, unless you have a heavy foot but that kinda defeats the point of economical running cars.
You can't even take the filter off anymore now it's part of the mot.

Thing is although it's generally used as a shopping car it does go out on the odd run, for example he took it to Sussex last week.  However I don't know what his driving style is like.  :-\

He wants to get rid of it now, so I was just wondering if there is a cheap driveway solution like taking it off and sending it to these guys, or can they be DIY cleaned with caustic soda or something.  :-\

Ask Mr DTM about cleaning them....he's told me before you can, its a case of swilling them out in summat, but i carnt remember what..... :-\

Tho i would have thought an 09 Golf , would clean itself....

My 58 Skoda (so same basically).....keeps doing a fast idle (1000rpm, 800rpm being normal) about twice a week (TB suggested an airleak when i mentioned it to him, which was a good suggestion) . But ive since noticed it also puts on the cooling fans on, in slow mode.....even tho, the temp gauge doesnt go above 90 (normal). Ive put it down to the ECU trying to get the exhaust as hot so it can to do a regen cycle....Also noticed it doesnt do it for a good few days, if its been down the motorway.

Probably clutch problem then lol.....ive driven a few cars that judder when cold.....when warm they are fine.....ive always put that down to clutch...as they only judder when pulling away in 1st and changing to 2nd.

Be wary of a dealer saying its the DPF, my skudo ECU, flagged that up, for lose of power, so was changed (£500), didnt fix the fault, turned out the turbo was fubared, but the stupid ECU, didnt mention that......ffs how difficult is it (if programmed correctly) for the ECU to tell if the turbo isnt working.....and its nowt to do with the DPF  >:(

See where you coming from Al.....but why the judder go away when warm  :-\
And if so, new clutch is usually recommended at the same time...
