Hi all

Got my mazda 6 2nd hand last Friday, I only had it for 2 days, since then it has been in the garage.

I have spent a lot of time since then reading through pages and pages on the net to try and find success stories of people in the same position as me who have had their DPF removed and never looked back.

I would like to hear about any body who has had a DPF problem and got it removed and ECU changed.

Who removed it?
How Much?
How has your Mazda been since?
And any other important info you think is relevant

If you feeling that you don't have any of the following information please don't post.

There are plenty of other pages with people talking about
"Oh it wont pass a MOT"
"what about the environment"
"oh Mazda wants ££££"
"I've been told this and that"
and of course
"bla bla bla"

Thank you for your time and i really look forward to reading some happy stories so i know that there is light at the end of this tunnel.

 

Hi James,

I can't help your directly but am surprised you haven;t got any replies yet but maybe all of us Mazda 6 owners are reluctant in having the dpf's removed although I have had a quote from a local company of £349. If I were you I would only take the advice of someone else who has had it done. This could be another market in which the cowboys are going to enter and make a hash of your car's ECU. From what I can gather it's quite complicated to removed all of the dpf software but beware of companies who will just remap your ECU to think the dpf is no longer there and leave the dpf in situ. You will want the dpf unit itself given back to you just in case it has to be put back in at a later date. A proper removal company will replace where the dpf goes with another piece of pipe or complete new exhaust. I am not sure how it will affect your trade in price for a car if it has had the dpf removed. It may be worth having a word with your local dealerships first about part exchange if you remove it.

Am looking for another car for my wife and came across a link on ebay of someone selling a Mazda 6 who has had the dpf removed. I am not sure if I can put the link on here as it could be seen as advertising but if you do a search on ebay for 'dpf removed' and put a tick in the 'include description' box you will find it. It's the only one there. Give the guy a ring and ask him. Hope this helps.

 

James, apologies but above info slightly incorrect. You have to select the following for the info to come up. Categories, Cars, Motorcycle and Vehicles, then Cars, then Mazda then the dpf removal in the search box.

 

Hello,

I have had some recent work done to my mazda 6 TS2 143. I can report that it is money well spent.

I went with 'flash remaps' in kent which was very local for me. The advantage was the fact that my remapper did not work on the hardware at all he stuck to the software side of things which he knew well and his sister company dealt with the physical dpf brick removal.

Smart guy is slightly wrong with the physical removal approach which is commonly used and is better for the majority of mazda 6 owners. All that is done is the actual brick is cut out of the DPF can leaving the CAT brick intact - and the can simply gets welded back up and replaced. No one will every know its not there and no one will ever care enough to check whether it is there or not. The main cowboy error will be taking out the CAT or messing up the welds. (just ask to see the brick when they are done - you don't want to keep it, it will be full of soot and quite fragile)

Obviously the sofware side of things is more complex and this is what your paying for. I had all the sensors recalibrated to read as though is no pressure change that might be caused by a build up of soot in the DPF brick and a system reset to tell the ECU that the DPF is 0% full. This will ensure no further regens occur.....ever!

I got this done as a precaution at 55k miles, having read about nighmare stories online of the oil level rising and forcing the engine to run off the deisel forced into the sump during regens which in the worst case can be terminal.

In addition I also had a performance remap which, combined with the DPF removal has seen decent gains in torque and bhp I haven't have these measured yet but I'm guessing 180-190 bhp and 320-335 lb-ft.

All in just under £500. I'm impressed

 

hello
I wasn't here for a while now cause I didn't have any problems with my mazda 6. Just wanted to give my opinon. I have had my dpf filter removed on the beggining of the year and have no probloem since. The car passed mot test - no problems.As far as I remember I paid about 500 pounds. But I've seen latest offer they do this for 395 pounds. Some sort of special offer . I would forget:this is the garage who performed succesfull dpf removal on my mazda6 Car Servicing, Garage, Car Repair and Diesel Diagnostic Services in Taunton
all the best all mazda owners.

 

Ah yes, forgot about the cat. Derv is correct. Can anyone recommend a dpf removal in Yorkshire or Lincolnshire.

 

Got mine done today in bradford. All lights done off and driving sweet FR&RTuning: MAHA Dyno Rolling Road Tuning: Stage 1, 2 & 3 Performance Upgrades

 

hi guys, i dont have any good or bad DPF issues to report, but thought i'd share our story for you to read.
When we test drove the car to buy it, the DPF light was on. so I 1st read up on the net about the mazda6 DPF issues the evening "after" i'd put a deposit down to buy one. rookie error i know, but it has turned out ok.

Its a 2006 TS 2.0l diesel 143 BHP, and i gotta say its a brilliant sturdy, tough, but also very quick motor car.

Our mazda, 2 years and 30000 miles on, has been great. The DPF has come on flashing quickly, twice, both at service intervals (15000 miles ish) in the mileage, i have put it in for a basic mazda service for £150 and £130 last time, and it has been fine otherwise.

Before the 1st mazda service, i did an oil change myself using 5W 30 oil as specified, i couldnt reach the dam filter so left that till mazda service, and it ran fine for another 5000 miles up to its trip to mazda.

My question is, can you source the oil outside of mazda? i'm led to believe it is "Special" 5w 30 oil that is DPF friendly? is that c r a p or is it true? surely 5w 30, is 5W 30???

As for removing DPF, i am mechanically minded, and know this would not create and issue with the functioning of the engine, but, i wouldnt get it done soley cause of the potential electical/ECU related risks involved...i have looked on a website of a company in london (south west i think), who do DPF removal, who charged less than £500, but i didnt persue it.

With our maz now on 90000 miles, the engine still runs and pulls fine, and i expect the DPF to come on again around 105,000 miles. fingers crossed.

Hope that helps or educates someone.
marty.

 

I just found this on the web . This company removed my dpf nearly year ago , I'm very impressed and have no problmes since. Well done p & p

 

Hi all,

I have recently had a problem with the DPF. First steady warning light, later flashing light. Mazda asked me £340 and after that they told me the regeneration didn't work...

My next idea was to have the DPF removed. But UK government has changed the rules in summer 2014 and any car that had DPF from factory and not found on the car (removal) will automatically fail the MOT!!!

With this, back to finding a solution... And I found one! There is a company in Hinckley that cleans the DPF filters in chemical bath combining with the ultrasonic technology. (DPF Clean Team) I just had that done. The DPF clean it self costed me £300 VAT included. But you have to deliver just the DPF, not the whole car. If you can@t manage that, find a garage, that can do that for you. This DPF disassemble and refitting costed me £140 VAT included. Overall £440, but guess what? I am sure, this will last other 80 000 miles without the DPF light.

I also asked the garage to clean the EGR valve as well. Chances are, it will be full of dust as well... Other £60. Don't forget to change the oil!

Good luck!
