'Here to help mate, you know what they say, what comes round goes round. The reset it just, resetting the eloys additive injection counter in the ECU. The cost is included in the figures I quoted earlier. As to washing DPF's out, well I've heard of some peeps trying it, but I would not waste your time. Because the DPF for the Focus 1.6 TDCi is a DPF/CAT combo. Bite the bullet mate, hell likely hood is six/seven years from now you wont even own the car. So you wont have to face replacing the DPF again. And think on, compared to petrol, you'll be saving a fortune in fuel over the years to come. You've then just to keep your fingers crossed your DMF does not decried to go "walk about"' Ah OK, so that's all built into the £250-00; I should probably clarify that the top up and regen is to be done by my independent guy who is also able to reprogram the ECU. I think you're spot on with biting the bullet, I just wish I could get in touch with my garage to let him know; I'm just waiting for the inevitable call from him to tell me it hasn't worked and I'll have an additional £500-00 bill coming my way I've just googled DMF and broke into a cold sweat :o .......thanks for that Thanks for all your advice again Catch. The DPF technically "can" be cleaned out, I have heard of some people who managed to pressure wash the cack out of it, and then use the filter for a good few thousand miles before it packed up. aside the environmental implications its not really adviseable, but it theoretically can be done. The ECU most likely will require a reset, as once the DPF has been replaced then the car may well need to be told about it, and also get the car out of limp home mode and clear any errors assosciated with it, unfortunately that would come with the diagnostics cost + vat, tends to be around the £60 + VAT mark, but its dealer dependant. Hi Jeebo, for the sake of a few thousand miles it doesn't seem worth it really and, being something of a wooly environmentalist, if cleaning it out will cause a problem in that area it's just another tick in the column to replace. If money truely is no object to you then you can just buy the DPF, or just buy a nice shiny really new Focus, with either CDPF or Petrol :) lol Sadly, in reality, I'm just a poor boy....... :P Thanks for your help with this guys.....you've done your good deeds for the day!
