Also, do you have a copy of the official workshop manual to spare?

Wouldn't a lot of problems be solved by manufacturers putting something in place where the cars trip computers actually tell you that it is performing a Regen and when it is complete etc and when it is needed. ie like Error DPF at 40% please drive above 2k RPM for more than 20mins. Then a countdown to completion? Just so drivers have an idea what the hell is going on. I have a 2.2 Sport 2011 and have no idea when it does this.

I notice my car runs on slightly after releasing the throttle whilst an active regen is in action. Makes the car feel like its not responding to letting off of the throttle.
Watch the instantaneous consumption too, it will hold out in the 60-70mpg range rather than 99.9mpg. Whilst off of the throttle for a few seconds.

Hi everyone,
Kinda new on here, as i have recently purchased a superb 08 Mazda 6 estate Sport 2.0 d ????
All good..until the DPF started flashing and car went into limp mode..
My question: Has anyone recently removed the dpf and had no troubles with mot?
If so i would appreciate if you know a garage that does it in Edinburgh.
Cheers

Reset the DPF light:

If you are lucky, it has not been reset for while and that is why it went on limp mode.

If it was not flashing and suddenly came on and went in limp mode, then it may not be a reset problem.

Change the oil and the oil filter if you have no trace of history.

If you remove the DPF/EGR, the car will be illegal but you can always find an MOT centre to turn a blind eye with that.

In general, you do not need to remove the DPF/EGR but you have to replace the oil from time to time and reset the service interval.

Keep in mind that the DPF/EGR removal will cost you more than the value of the car.

Somebody else had that. He managed to reset EML and start the regeneration. This did not happen in one go. While the regeneration was happening, the EML would kick in and stop it. So a new reset and a fresh regeneration. This happened several times but at the end worked.

If the car drives, I would just drive it without stopping, i.e. no traffic lights route. Sooner or later, it will regenerate.
