Hi Guys. I thought that I would share with you all, my experience that I had with my Mazda 6 TS 2.0 Diesel (2008). I have only had the car since January and it always 'missed' at around 1800rpm, just a very short, hesitant lack of power, mainly on the motorway in top gear. I knew that something wasn't right but I put up with it. Anyway, back in the beginning of May, it very suddenly got much worse where the EML came on and all sorts of other warning lights came on and off, (ABS etc). The car went into limp mode but got me home. I left it over night and the next day, it was worse. It started ok but had no power and I had a job to drive it so I parked it up and booked it into my local Mazda dealers in Cardiff. I struggled to drive it there but I got there. They kept it over the weekend but I eventually got a call to say that I could pick the car up. I was told that the cat was blocked and the car tried to do a regeneration but failed due to the blocked cat, causing a lot of back pressure. They did a forced regen and managed to unblock the cat (don't know how). I was told to monitor it and see how it goes but if all fail's, I might have to fork out for a replacement DPF!!! My place of work involves a 40 mile motorway drive so I had plenty of chance to give it a good blast to clear out any further soot and hopefully prevent it from happening again. However, I still had that occasional 'miss', 'hickup' or whatever you want to call it. I started to do a bit of research on DPF's, cat's and their problems and came across an additive called 'Cataclean' which claimed that it not only cleans the cat, it also cleans DPF's and the whole of the fuel system in general. The best price that I could find was with Eurocarparts at £13.99 a bottle. I'm sure that Ebay sell it cheaper but I don't trust a lot of products on there as there are a lot of fakes around. So, I bought a bottle and followed the instructions which states that the whole bottle is to be added to around a quarter of a tank of fuel. Then drive the car for at least 10-15 minutes before adding more fuel. What I did was drive the car over a couple of days to use up the quarter of a tank of fuel then refueled. Lad's, this stuff works! Not only was the annoying hickup gone, the car definitely had more power, crisper acceleration and an improved MPG. Definitely the best £13.99 I have ever spent. It certainly worked on my car and I have not had any reoccurring problems in the last 7 weeks. It does say on the bottle that it can be used 3-4 times a year if required unlike other additives that have to be added to every tank full of fuel. Worth a try guy's, if you are having similar issues with your car.
