Hi fellow Lexus drivers, I appear to be having a problem with the diesle particualte filter on the car. It is in limp mode all the time. I was wondering if any one knew how to clean the filter, or even if this is possible. This seems to be a very common problem with the diesels and alot of people out there seem to have resolved theor probs without having to replace the filter which requires a second mortgage it seems. Doea any one have any suggestions, can it be cleaned or does any one know where to get a second hand/resonably priced one from?????? thanks for you time in advance
