Hi all.
Just bought a 2007 2.2 hse, and after just a couple of weeks, the bloody thing went into limp due to full DPF. Took it to dealer who replaced old software wit an uppgrade and did a forced cleaning af the darned thing.
It helped for half a day. Went back to dealer, and they couldent do much as they said the dpf had to much soot.
As I were on vacation at the time, I couldnt do much about it, so it had to wait until I got back.
First thing; I jacked the car up, removed the DPF unit, laid it on the work bench and cut the top of it. Then knocked every piece of DPF material out of it, and cleaned it.
Weldet the top back on again, sprayed heatresistant coating on the welds, and mounted it back.

As I have a car faultcode scanner, I deleted the faultcodes, and for a few hours, it seemed ok.

Due to now fawlty values to
The differential pressure sensor, the faultcodes returned.

I called a local tuning company, and they stated that they could do a remap of the ecu to prevent faultcodes from DPF ever to return. Cost; aprox 400£, or 3500nok.

I have now done this fix, and have driven for about a week with no problems.

In my opinion; DPF sucks, just remove / modify the darned thing.
As the 2007 is a Euro4 class, it wont matter for the m.o.t.. There are no problems, only solutions...

Best thing for DPF's...get rid of them. Manufacturers are now owning up and referring to DPF's as serviceable items, basically they will fill and need replacing at some point.

Check out the pictures in this thread, yours will have looked similar.

Nope, DPF doesn't do anything with the CO2. It catches soot, and yes burns it into finer particles when at high revs/load.

Only change is that it will register a higher reading on the smoke test at the MOT, but they're clean enough to pass without anyway. It's still the same smoke test (As far as I know) that our pre-dpf 2009 model has to pass

Hi Deuteronomiser, if you want to know for sure if your car has a DPF fitted I can check for you, just pm me your full VIN and I will look it up fot you

...or just put your finger into the exhaust - if you take it out black covered with ash there is no DPF in your car.

...agree that best DPF is that one which lays next to your car but we have quite good experience with cleaning additives for DPF which are added directly into the tank and also with DPF flushing liquids.Are these additives sold in UK ? Anybody tried them ?

The sooner DPF removal , just like cat removal, becomes an MOT failure point, the better.

Diesel particulates are real nasties and I'm only too happy to be burning them off in my DPF; 19 months and 65,000 miles so far and the only problem has been (an easily fixed) crack in a pipe leading to the DPF sensor. I can live with that.

What we need is a sensible petrol option for those who don't drive their diesel long and hard enough to justify running one over a petrol.

Sorry Tigger but it IS NOT an automatic MOT failure by removing it. If you ask a chain they are likely to say it is, but the proof is when you take one and it passes  Mine: 2012 Golf GTI Edition 35

Okay so I have a 2009 TD4 HSE and I have been told that it has a DPF but as yours didn't, mine might not. So am I occasionally wazzing up and down motorways for no reason?

Also, if I had my DPF removed, my Bluefin remap would be wrong.... And what would need to be out in the space where the DPF was?

Finger in the exhaust to check, as mentioned, is the simplest method...will be covered in nasty black soot if you have no DPF, clean otherwise


Apparently Petrols are going to be getting 'GPF's' soon

It's getting so barmy now that Volvo trucks on their 'EU6' vehicles need 4 stages of after treatment in the exhaust, all increasing consumption, making it harder to get exhaust gases out, and even injecting fuel on the power stroke (which is wasted fuel) just to make everything hotter to burn a bit more gas off.

At this rate we'll have spme sort of device over our mouths soon to catch CO2 and force is to go for a run every week to 'burn it off'  Mine: 2012 Golf GTI Edition 35

Tigger doesnt say it is a failure

He says the sooner it becomes a fail for it not being there, the better, a subtle but important difference.

The point being that diesel particulates are harmful and removing the DPF may benefit yourself but cause problems for many others who suffer from there effects.

He does!

Tigger is talking about DPF removal and I'm talking about CAT removal. I think you've confused my CAT comment with his DPF comment, if that makes sense.

Tigger says. "The sooner DPF removal , just like cat removal, becomes an MOT failure point, the better".

So, according to Tigger, CAT removal is an automatic MOT failure. It isnt on a diesel. Past: FL2 TD4 HSE Auto

The wonders of the english language, I wish I had listened more at school

Yes, Dave, there is an argument against my final paragraph and a very valid one you have. it all comes down to the idiots in Brussels in the Department of Beaurocracy.
It's a similiar scenario to the wind turbine debacle, alledgedly more CO2 is produced creating the concrete plinth than the turbine can offset in its lifetime

I am with Big Dave on this one. All these things are fitted for one reason...to allow manufacturers to claim lower smoke/emissions and hence a lower tax band with no reference to how long they will be efficient. IMHO it has not been thought through properly. I have watched with horror the workshop process for "regenerating" a DPF on Fords.....4,000 rpm for 20 minutes! Not very environmentally friendly! Don't get me wrong, I am all for lower pollution but I am not sure this is the way to go. It smacks to me of the old EGR issue. The damn things are fitted, go wrong, cause more pollution/fuel use than a non EGR engine, use energy/resources in replacing them with new ones etc. etc. I removed the EGR from my TD5 and it got far lower smoke test figures without.

The future is more money/time spent on engine and fuel system design. John
