    This evening I have had my glow plug module replaced which has cleared all my glow plug related faults and hopefully cured the rough idle when the weather is cold. So over the coming days I want to take the car for a drive on the motorway just to make sure the dpf will regen (bit paranoid about...

    I have had issues with my DPF since my remap on my 2008 335d at the end of May which I have resolved with much help from DIS. I got it for registering my battery and have used it on a few things, but mainly to diagnose the issue with my DPF. So I thought I would pass on what I have learnt. 1...
