• Mazda 5 2.0 diesel Sport Nav 71K miles - DPF regen exhaust gone funny 31 Oct 2010 (Forum)
  Hi all just wondering if you couild help with this at all, the above car engine light came on and i was told it needed a cat regen, went and got this done at the mazda dealers, after getting new injectors (wallets still hurting) they told me it was too blocked up and would need a new Cat Converter, however they did offer to try a new solution which has come onto the market apparently which is 95% effective (didnt ask what it was called) in these situations and if it worked it would avoid me shelling out a shed load on a new cat converter / dpf filter,  suffice to say it appears to have worked and the car is working fine, but the exhaust is making a fuunny sound in the 30-40 speed range (3rd gear) the best way to describing it would be a loud Brrr noise kinda similar to how my old 306 diesel sounded when the back box fell off once doing a quick visual the exhaust seems to be fine, i will ring them tomorrow to find out if its normal, but has anybody had any experience of cat / dpf regens, will the exhaust sound go back to normal in a few days or am i worrying for nothing, its my 1st car with a DPF and i have only had it about 3 weeks so i cant compare it to how it should have sounded. any and all suggestions much appreciated and thank you to all contributors in advance.

• Mazda 6 SL 2008+ - Mazda 6 Handbook - Should be amended/revised 16 Mar 2010 (Forum)
  I need to ask the question of whom thinks the handbook should be changed for the following reason. DPF - I am sure a lot of you know of the problems the DPF system has caused us all? Does it mention anywhere in the handbook that if a DPF regeneration is not carried out what are the consequences?
• MINI Cooper D - Mini CooperD DPF fault light - needing urgent help 2 Jun 2017 (Forum)
  It doesn't help that I think there may be a slight electrical issue with the car, I've had dash lights for ''pass air bag off'' intermittently lit on start up and also external light failure warning light. I've seen there are treatments for the DPF, however I do not want to spend money on this if its actually something faulty elsewhere causing the light to come on. If I get a diagnostics test done will it just reflect what the display is showing or will it know 100% if the DPF is knackered?

• Yaris Diesel - Toyota again!! 1 Oct 2017 (Forum)
  Since having it serviced a year ago last may and again this May  I've had nothing but trouble with the Dpf. This year I took it to Toyota for its service , within 2 weeks the DPF was blocked, they did a regen but as a gesture of goodwill they charged me half which amounted to £80. 1200 miles later within 3 weeks (most of that on motorway) it found it's way back into Toyota with a blocked DPF.
