DPF replacement...$4000!...Anybody know a good exhaust mod place in Melbourne?

[ryder01]

Hey Guys,
Have recently bought a gt tdi 08' with 104,000ks...
DPF light has come on and stayed on after 1000k's...
Long story short, fully blocked, forced regen at VW didnt work, $4000 replacement! .

So I think I will have to go the DPF delete option...question is though, can anybody PM me an exhuast place in Melbourne that could take out the core of the DPF (to still look standard) before I get Custom Code tuning....

Thanks for the help!!

You can always try cleaning it out yourself, look in this post. Nothing is guaranteed but it's worth while to try.

made Custom Code will only do the tune with the Milltek DPF delete pipe I think (Gav chime in please!)

all up the DPF delete and tune is WELL under a new DPF from VW

PM h100vw and he'll answer all of your questions regarding the DPF delete pipes and the tune

[Greg Roles]

I do believe golfie above is indeed correct, that you have to get the DPF delete "pipe" from CCodes sister company JBS in order to have the delete done. My JBS pipe has a serial number on it, and according to the mighty Gav, the serial is linkled to the tune. If you do need to go the CCode tune, Gav and I have already spoken and you can have my pipe, as it takes forever to ship them here surface. I'm in no rush to fit and tune my car, so happy to help out someone in strife, and Gav can get another one on the slow boat for me.

There ARE other companies offering DPF off tunes in the UK etc, but to my knowledge and fairly extensive web research, only Custom Code have got it right thus far. AMD was looking good, but there's been a number of problems since. This will change, but for now it's a one man show!

The upside to all this if when you DO ditch the DPF, you have a HEAP less exhaust restriction, and your fuel economy for normal driving will increase rather nicely. Of course if you use the power all the time, then fuel is going to get burnt! There is a "mild tune", and with it being a second car, that'd be the way to go. I've read the standard "wild" tune is ultra responsive on the pedal, and quite aggressive.

Sadly I reckon you are the first of many people who are going to get stung with clogged DPF's in the next several years, and all you guys blissfully ignoring the problem are on a ticking bomb I'm afraid. Mine will clog one day too ( if it was left on ) but with the steps I've taken, I figure I'll get the maximum life out of it.

The other option is, of course, to cover Gav tuning my car, and I'd be willing to give up my 60k DPF, but theoretically any DPF is only supposed to last 150k's, less, unfortunately in your case. I've no way of guaranteeing the actual lifesapn of my DPF, but it has had an easier life than anyone else's I know of!

Didn't you have some links to FAR cheaper DPF's overseas transporter??

I am OK tuning the car with the standard pipe modified, I checked that and they have relaxed their rules somewhat.

It also seems that you can now buy the pipes from Milltek but as Greg has mentioned there's not a large field of tuners to pick from.

If you wanted to stay well within the law, cleaning out the VW DPF and fitting a 3rd party one elsewhere in the exhaust would work.

I agree with Greg, we should all be buying shares in DPF pipe manufacturers now before the boom.

tip of the old iceberg eh???

A few weeks back I had to "modify" the cat in my missus' diesel cabrolet (still has the gasser exhaust system on it from when the engine was swapped) because it became completely blocked

i reckon i gained about 15hp from blocked to unblocked - thats a lot when you only have 50hp to start with!

Hey Guys,
Thanks for all the great replies. I think I'm going to go down the path of the the miltek And tune...Greg I'll pm you about your pipe.

Out of interest sake and for everybodies knowledge in future (which I'm sure will happen) I'll pull the old one off and try to clean myself and see what happens...spoke to an exhaust place near by yesterday and they said they had pulled some (not vw mind you) and did the soak and clean with a air comp/high pressure from the outlet side, so backward flow and it had worked on occation. I'll let you all know how it gets on.

Such a pitty...for a car I couldn't stop raving about how good it was to mates when I first drove it, ah well, I'm sure I'll grin even more with de-dpf and tune when the turbo kicks in.

Cheers and thanks for all the help.

Hi Greg,
thanks for all the info posted mate. Great forum for good quality info you guys have.

So I think the miltek and tune is going to
be the go. Could you let me know how much you would part with your pipe man? I can sort out the freight side from this end as I have a star track account at work.

Thanks again mate for the help. It's been a quick crash course in DPF Tech the last three weeks.

Ryan

PS-Woops...meant to send this as a PM to you Greg...oh well....

[GoLfMan]

mate I'll be haggling you for a ride when you get the 170kw 450nm DPF delete tune !

[Greg Roles]

I'd suggest trying to backflush the VW DPF will be temporary at best, and unlikely to get you much more life at all. The channels in the DPF are not straight through, at all, and it's more akin to honeycomb in a Violet crumble than a "cat" that most people think of. The actual precious metal coating that acts as a catalyst also gets covered and as the surface area decreases, it clogs more and more until it completely fails.

Feel free to give it a go, but WHY would you go back from HEAPS more power and torque with reduced fuel use???

[ryder01]

Hey Greg,
No I wasnt saying I would try clean the DPF for use afterwards, I will still get the Delete done as I can only see this becoming a problem again. I meant more out of interest for people going forward who have the same issue and may want to know if it can be cleaned out.

Cheers

i wonder if you could just burn the soot out "on the bench" so to speak... using an acetaline torch to start it . Hmmm....

Who likes the idea of an acetaline injector post turbine?

(the "wink" indicates a joke....)

Great post Ryan, I too will be up for one of these bad boys soon, with my 08 gt I'm just waiting for my warranty to expire.
Question: are u going to um..... "hi flow" the cat as well?
And this might be a question for the other boys too, can anyone with half a brain fit the milltek/ custom code chip, or do we need to ship our cars to the uk?

[h100vw]

Gregski, the chip is actually a flash for the ECU. No need to ship it to the UK. If you are looking to get a DPF pipe, It'd be good to know when you would be looking at? Sometime in 2011?

Gavin

[Gregski]

Sweet so when u say flash you means it's just a matter of plugging it in and off you go?

Mate how long will it take to arrive? I know the other boys waited 4+ months?

Cog you should have an auction for your pipe and chip mate, you might have a few hungry buyers!
