Hi all grate site, we have a problem with are c3 we got her a year ago it was love at first sight, the dpf came up on the test drive and we were told it's OK she's been owned by a old guy and that should go away with some good driving, well a 2011 model on 21000 miles makes sense to us, and the garage has a very good reputation, so we had her, we Pope back in a few times because of it same answer drive it hard and yeah the particular filter warning light went went off. Well in one year she's up to 34000 miles, and all he'll broke lose, it's all ways on, thay had her in, cleared the light, re gen the filter, thay told us it was the temperature sensor on the dpf, that's change cost us some money, it's realy stressing us out, now thay said we can't tell what fault it is take it to a citroen garage thay can pop it on there diagnostic kit because there's can't do it, so we have threatened the ombudsman on them because...well this was the first fault on the test drive and it's gone form just telling us now and then to limp mode and all thay do is cancelled the fault and send us away. So now thay have offered to change the bag for a discount price, lol, two day job apparently, and we're convinced thay ain't got a clue, so if you have read this far thank you, Questions...1 do you guys think it's worth paying a citroen garage to diagnostic her and give us the stright line take the hit then go back at the garage? 2 what could possibly be the problem, been regenerate, new temperature sensor on the dpf, have noticed that the dash external temperature is now not working just blank too? 3 if it's the bag is this a job another garage could do with say cheeper parts, save us some money! Thanks for reading
