I have not been on the TOC for some time now,and indeed not used my Auris much either only doing about 600 miles between one MOT and the next for the last couple of years. What has brought me back is after reading an article in the motoring supplement of the Eastern Daily Press about a diesel specialist in Norwich who have purchased a DPF cleaning machine from Italy, one of only two in the country. The article gives examples of back pressure etc before and after cleaning with this machine and quotes After cleaning to bring the DPF back to 98% of a new unit. The cost of removing and cleaning and refitting is from £150 + vat which is a big saving on the many hundreds of pounds a new DPF can cost. Anyone interested can watch a video on www.edsnorwich.co.uk. NO I have no connection to this firm just passing on the information to maybe save someone a few bob.
