DPF Troubles - break, sell or fix?
Discussion
Hi guys
I have a 55 plate Mazda '6, with the 143 bhp 2.0 Diesel engine in it, which I bought 4 months ago for £3550. Recently, I had a regularly occuring DPF light, which came on for 10 minutes of motorway driving then went away again. I asked a local garage to remove the DPF and to fill it with a specialist cleaner, which they said they have done on other vehicle.
They did this, and have also carried out a DPF regen using some generic Snap-on diagnostic equipment. The problem is, the car keeps popping up the flashing DPF light, and occasionaly the engine management light. The fault codes are reading as o2 and dpf temperature sensor faults. I am currently diriving around with a fault code reader plugged in so I can keep clearing the codes!! When cleared the car boots fine and drives well, when the DPF light is flashing it still boots, but with stunted performance.
The situation i'm in is I run my car for work, and receive a car allowance for doing so. My boss insists I have a reliable car, so I have this morning robbed all the spare cash I have and agreed a purchase on a PD130 Octavia.
So, I now need to regain as much money as I can on the Mazda, do I:-

So, I now need to regain as much money as I can on the Mazda, do I:-
- Keep trying witht he garages to fix it, then sell privately (a new DPF is silly money, over £1k)
- Sell it as-is, stating the issue and get the best I can for it
- Tear it to pieces in my garage and sell engine/ box/ body and scrap the rest
- WBAC it and wave goodbye with zero fuss?
king good reason to avoid Mazda 6s. They have many inbuilt faults with the DPF being a minor one.eltax91 said:

You do know that your local remapper will remove the DPF and map out the DPF functions on the ECU for £300-400? Best solution for anyone with DPF issues.
My local folks are doing the service for the 2.0D Mazda 6 and the 2.0TDCI Mondeos for £400. They remove the DPF, knock the guts out of it, refit, then map out all the DPF functions. They'll also add an extra 30hp if you want while they're at it. An extra £80 they'll give you your DPF intact, and fit a bypass pipe.

This is what I will do if my DPF starts giving trouble and I'm no longer worried about main dealer service history.My local folks are doing the service for the 2.0D Mazda 6 and the 2.0TDCI Mondeos for £400.

I've been downb that route already. Nobody except the expensive SinSpeed can say they have done this. They all say they've done it on a mondeo, not on a Mazda 6. I went to the hassle of taking it to a remapper at Rockingham race circuit. He tried for 12 hours, and good not read the ECU due to the encryption in place.My local folks are doing the service for the 2.0D Mazda 6 and the 2.0TDCI Mondeos for £400.

So, it's a solution for all DPF's, except Mazda's.

My garage is quite friendly, so I'm only out of pocket £70 currently on fixing the Mazda! They are going to try a further regen and recalibration on Friday.what MY is the Octavia?
The Octavia is a 54 plate, PD130 WITHOUT a DPF.

This is a real pity, as I have a 53-plate Mazda 6 (pre-DPF) and its a really great car, over 120k miles now and drives like its brand new
Yeah it's a massive shame. If only I'd have researched into DPF's first! I just cannot have an unreliable car, my work depends on it. My previous Octavia was faultless, so I'm just hoping this new one will be too.Gassing Station | General Gassing | Top of Page | What's New | My Stuff
