Anybody had this done? and how much did it cost?

Spent Saturday getting prices for it doing on an Audi A3 and the range of prices was huge.

I just disabled my EGR - took about 5 min, then there are much reduced particulates so DPF doesn't get clogged. I'm sure there will be loads of posts online about the the best way to do it for your engine

Work done to remove the diesel particle filter and exhaust gas resuscitation valve.

Had quotes between £300 to £1000

A good job isn't cheap put over paying isn't fun either

DPF has collapsed, cars in limp mode and dashboard lit up like a Christmas tree.

Had a laptop plugged into it and only came back with the DPF fault code. The car isn't mine just trying to help my brother out

dpf on my mazda 6 was £400. and that was from a friend not a garage.. not cheap as they have to remap computer but worth it.unless its blocked just rag it on motorway in 3rd gear for few miles that will clear it.

I learnt the hard way.

Around £500-£600 is looking likely

Quoted £1000 to sort it and put a new DPF in, but no need for that nonsense

I've been having problems with the pipe that runs from one of my exhaust headers (oops, sorry, we call them manifolds over here, lol) to the EGR valve.

Basically, when I swapped the headers for performance items, the EGR outlet wasn't quite in exactly the same place as stock.

Had some issues getting it to seal properly, until I then noticed that in all the tweaking I was trying to do, a fatigue crack had developed.

Have tried replacing the pipe, but can't get the original OEM item (My car was built in 1996) as it's no longer produced, so I have had to improvise.

Had some more difficulties, so have removed the pipe and blocked off the holes, but left the valve itself in situ - otherwise the PCM throws a code if it can't operate the valve.

Unfortunately, I am occasionally getting a P0401 code (Insufficient flow), so it looks like I need to find a fix for the pipe again.

Fortunately, I have a code reader, so clearing the code isn't a problem.

My code reader can read the Powertrain codes from any vehicle worldwide that complies to OBD2 (or EOBD2)

In Europe this applies to any petrol vehicle from 1st Jan 2001 and any Diesel from 1st Jan 2003.

My car, built for the US market, was the first year of OBD2 in the states.

I can only read Airbag or ABS codes for USA vehicles at present, but I am looking to download firmware to allow me to include European and Japanese vehicles.

For some reason though, French vehicles are separate - and my device only has sufficient memory / storage for 3 of the 4 available modules.

I'm not going to be bothering with French.

Then again, for my own purposes, it suits my needs for now and the future as I will be sticking to US imports - but it's nice to be able to help friends out.

not sure how the egr works on audis but often the valve is controled by a vacuum. pull the little pipe off the vacuum pump (possibly located on the end of the cylinder head. and seal the pipe (a round nail and a jubilee clip will do). the egr stays shut and is thus disabled. check out some audi owners forums and type disable egr into their search box.

You need to be aware that the EGR system forms part of Emission control and as such, if the PCM detects a fault it will illuminate the MIL (Malfunction Indicator Lamp) which is a MoT failure.

It may be possible to 'program out' the EGR - but this will cost £££'s - if you can find somewhere that can do it.

Essentially, the EGR valve is designed to feed exhaust gases into the combustion chamber which results in a slight drop in engine temperature - which in turn, results in lower emissions.

what i metioned won't suit all cars, especially the more sensors they have. it does work on older peugeots though. not sure about new ones. a mate had a ldv diesel van (silly idea i know). he had a problem with the ecu and countless other bits of brain. all the local garages were quoting stupid amounts to replace eveything. we had a go at dropping the engine out and removed everything that wasn't engine, re-calibrated the injector pump. being diesel it worked. the mot guy was ok about removing it all, his angle was if something is fitted it has to work, if it's not fitted then it doesn't need to be tested.

I'm only familiar with it on diesel engines. By leaking some exhaust gasses into the inlet fuel/air mix, it displaces oxygen, resulting in a lower combustion temperature, which produces lower NOx emissions. However, it increases the amount of particulates (soot), hence the need for a DPF.

In the UK, the MOT emissions test is only for opacity, not NOx and thus the EGR is superfluous. In fact, deleting it in software or manually disabling it, improves mpg, bhp, torque and reduces particulates. Thus helping you pass the MOT and it doesn't clog your DPF.

I understood what you meant

I was just trying to add to the information you posted.

You're right also on your point on not testing components that aren't fitted.

Then again, I had an issue with my ABS last year - well, pretty much the whole time i've had the car - but it was never a problem until dashboard warning lights came under the test.

Can't exactly remove all the ABS components from my car - for example, the front wheel sensors are part of a sealed wheel hub assembly - and ABS was standard fit on my car.

But, as my ABS light goes out as it should after start up it's not a problem. That it comes on again over 5mph is not an issue for the MoT

Back to the op though, the first thing I'd do is remove and clean the EGR, as I understand it, on diesels at least, it's the single most frequent cause of these symptoms.

Not sure what you mean by DPF collapsed, if it's physically damaged then it will have to be replaced or bypassed. If it's just clogged, a forced re-gen might sort it, but first you have to get the engine running properly, and when fully warmed up, drive for 20 min or so on the motorway at around 4k rpm.

My mate Jeremy took one look and sad WTF you've gone and installed a KKSG. I just laughed. Not everyone has a diesiel RTVW to activate their SWRY, do they? Thinking of upgrading my Citroen 2CV next.

Not sure about the mainland, but this is becoming an MOT failure soon in Norn Iron. I know we have a slightly different system, but might be worth double checking for any planned changes.

To be fair, if you're getting DPF/egr issues, chances are you're not doing the mileage to see the benifit of a diesel, and may actually be a bit better off with a petrol motor.

This is true. It will be failure all over soon. If you EGR clean and do the mileage as said above all should be hunky dory with modern diesels

Quite. They are fitted for a reason.

Type approval and Emissions regulations.

Emissions tests on MoT's depends on the year of manufacture, and is therefore more strict on newer vehicles.

Depends on how you drive it.

Cheers Topsy.

Unfortunately for the OP deleting the DPF is now illegal and any tuners found carrying out the work are being heavily fined, the car also won't pass the MOT with it missing.

Deleting the EGR is a great idea and really improves reliability and helps the turbo spin up earlier, it also improves the emissions.

There's two types, vacuum and electronic.

Vacuum types can be disabled by disconnecting the vacuum feed and fitting a blanking plate. Electronic valves require a tuber to delete them from the ECU map. It should cost around £150-£200 depending on the car and where you go.

This is pretty much bang on.

Well go for it if you can. Make sure you also fit a cored (emoty) DPF in place of your old one as they're visually inspected at MOT time.

What garages and dealers won't tell you is that the EGR valve is often not broken, it just requires cleaning. But it's just a 10 minute joband requires nothing more than a squirt of carb cleaner and a spanner. They just love charging you £150 for a new part when the old one could just have been cleaned...

Your right and I'm pretty sure the rules change next spring and it's fairly stringent on egr pdf with big fines for there removal or not working so I'd double check with your mot station before doing any work.

Technically there doing you on tax avoidance as your road tax is cheap for those vehicles because the egr and PDF takes out so the nasty stuff, if they find them removed they back tax you for excise duty plus a 1000£ fine.

Sorry but you're mistaken. They don't connect to the ECU to check the DPF. It's a visual only inspection specified in the MOT testers handbook. Most garages charge £30-£70 (even more at a dealers) to run a simple 1-minute diagnostic, they're not going to plug into the same port and scan the ECU for signs of tampering as part of the MOT for no extra charge....

No sorry I'm mixing my words.

I thought the new change involved lighting all the warning lights on the dash and then they all have to go out , if any remain on its a failure, now I'm not positive but I do seem to remember having the conversation with my mot guy last time I was in.

So my point was if you removed it from the ECU would the light on the day light with the that test?.

Like I said it was only a conversation with my mot guy that started with egr valves as I'd blanked mine off with a plate!

I'm sure I read in my mot station that they check the dpf is in the engine management still and that it's in place.... I'm not absolutely sure but I'm thinking I read it's a 1000£ fine plus the car will not be returned until it's refitted.

Sorry but you're mistaken. They don't connect to the ECU to check the DPF. It's a visual only inspection specified in the MOT testers handbook. Most garages charge £30-£70 (even more at a dealers) to run a simple 1-minute diagnostic, they're not going to plug into the same port and scan the ECU for signs of tampering as part of the MOT for no extra charge.....

No sorry I'm mixing my words.

I thought the new change involved lighting all the warning lights on the dash and then they all have to go out , if any remain on its a failure, now I'm not positive but I do seem to remember having the conversation with my mot guy last time I was in.

So my point was if you removed it from the ECU would the light on the day light with the that test?.

Like I said it was only a conversation with my mot guy that started with egr valves as I'd blanked mine off with a plate!"

It's only an advisory in that case. The only time it will fail is if the warning light for the DPF stays illuminated, same for the ABS and airbag lights. The engine management light is only an advisory and usually the EGR valve is covered by the management light not the emissions light because it's conected to the inlet manifold....

Yeah mines to old for an engine management light lol.(18 year old vw van).

I just got sick of the egr sucking in crap so I blanked it.

Runs alot better without it and I think probably a little more frugal .

Although to be honest I'm running mine on homemade diesel, so I upped my injectors and pump o rings last year and have just put myself a preheater on so hoping to give it a whirl on 90/10 mix of cooking oil(recycled) and petrol.. Only slight problem is it still whiffs of fish and chips while idling

Is it def labelling it as dpf fault or does it come up saying anti pollutant fault? Only saying as I recently had troubles with my fathers citroen c5 saying anti poluttant fault and I went round the houses finding the cause I instantly thought dpf as he only does short trips drives like his age and never gets it hot so I stripped the dpf off and pressure washed it out after a soak in petrol. Absolutely tonnes of gunk came out so out it back in and all seemed well for about a week! Went back and spent a very cold evening replacing the egr valve which was an absolute mission on this particular engine which again seemed to cure the fault but only for a week . I only changed the egr as a friend with a code reader said this was at fault! So then I poked about abit trying different things for a week or two whilst I was waiting for my own code reader to turn up any how when it did it came up with a fault for the throttle body motor being low resistance .... Turns out I think the seals around the butterfly shaft had failed and oil/other crap had got into the motor and caused the fault all along which is something that no Internet forum I had searched had ever even hinted as a possible cause. I'm only saying this as an anti pollutant fault is commonly first associated with dpf /egr but in truth it covers just about every part of the engine efficiency system.

I removed the egr pipe from our mondeo tdci and the turbo hated it. Wouldn't spill and no power. Using an egr blank plate now on the inlet manifold side and noticed a little more smoke when first reversing. Would do a full remove with a remap. No dpf to worry about on mine

Join the club I would never have one but my dad loves them and i can't get through to him how renowned they are for faults ESP of the electrical kind no matter how many internet reviews I show him!!! I have now told him if he buys another which he is indeed looking for I am in no way what so ever getting under the bonnet as its his own bloody fault!!!

To be honest I was trying to get him to buy an a6 estate and when I went to show him they're reliabilty score they were horrendous as in the chart was that 100 was average anything more was bad anything less meant good the citroen c5 scored 150 and the A6 scored 468!!!! I quickly closed the Internet page down before he made me eat my words for the rest of time!!!

Sounds like my exes Renault Megane. That had a reoccurring EGR fault that couldn't seem to fix. The valve was working fine and I'd checked the wiring and all was well. Many hours were spent with a multimeter checking earths and positive/negative feeds. I eventually traced the issue to.....

The aircon pressure sensor!

Yup a faulty aircon sensor was causing an EGR fault and was causing a misfire......bloody French cars...
