Hi mate you need to have it plugged in and then re gen it, tbh a long thrash on the motorway should put it in to re gen but as the light is now on it will more than likely have to be done with VCDS (although ive never re gend one with VCDS)

Whats VCDS??

Fault code read and a lot more, if you own a VAG car then VCDS will become your best friend, it can code read, reprogram features, view live data, its close to main dealer diag tools

where abouts are you, there may be a member on here who is close by who can plug your car in

try doing about 60-65 mpg on the motorway in about 4th gear. basically you need the car's exhaust gases to be the hottest they can be. once they reach a certain temp..it will burn away the crap clogging the dpf.

In the 3 years I've had my golf, I've only seen the DPF light on once

As already said, you need to be doing motorway speed really to force a regen.

If this fails could be looking at new dpf, or dpf removal  :wink:

You can remove them, ive never removed one completely, i have replaced them tho
A DPF is a silly idea tbh, but if you were to drive on say a motorway once a months that would do an auto re gen as the dpf will get to temp, im not sure where you could get a kit to remove it from my be darkside performance?

If you manage to get a full regeneration done, & you use the car to a point where the car can regenerate occasionally, you should be ok.

If you can't regen, you could replace the filter, don't know exactly how much, but I would imagine approx £900-£1000 genuine. Don't know if aftermarket are available.

OR

You could by a bypass pipe to replace the DPF. With this, you MUST have the DPF operation mapped out.

Where are you based?

If you wanted to get rid of the DPF, Miltek do a delete pipe. Mine is in for DPF delete next month.

dare i be so rude as to ask how much thats costing? and are you having a re-map done at the same time?
Title: Re: Diesel Particulate Filter
Post by: Matto on February 23, 2012, 12:12:59 am
I am not having the delete pipe, just the middle knocked out. I am having a remap and also fitting an EGR delete at the same time as that will need mapping out aswell. Costing me a smidge over 500 notes all in but that was with some show discount.

I'm having it done at Shark Performance and I know they do a Stage 0 which is just the DPF removal without the remap so you could go down that route if your abit strapped for cash.

~UPDATE~
thought id take it out agian for a GOOD run today this time time see if i could clean the DPF by keeping the rev up and the gears down just about to set out on the open road and!BING!engine light and coil light came on!gutted car seems to of gone into"Limp mode" max RPM i could get was around 2700 :scared: absolutely gutted
took it to a local garage they said they can clean the DPF(not sure how) but want to charge me £180 for the pleasure!(THERES NOT MINE)
does that sound right?
cheers guys
Title: Re: Diesel Particulate Filter
Post by: perky85 on February 23, 2012, 07:02:43 pm
find out how they are going to clean it out?

some garages use a flush but this only works temporarily as the VW dpf's are not designed to be flushed, they are designed to be replaced.

Some garages use the jet wash  :surprised:

which ever route you choose is going to be costly, the cheapest is to remove dpf & remap.

I have removed a few now due to this issue

Once its in limp mode you will struggle to do a full regen without forcing it via diagnostics.

Heres some info:

Thats good news then.... Was going to give you the number of a friend of mine in Grimsby but you got sorted so that's cool.... His website is a little poor but he obviously knows what he is doing and his mapping is a good price...

I had a Chipboost map on my old Fabia VRS and had 50,000 trouble free miles with it.  Glad you got your car sorted :smiley:
