Welcome to the Forum

If you drop down a gear or two to increase revs what happens? When was the car last serviced ? A misfire could be Coil Pack failing Plug failing a vacuum or air leak on the inlet, I would start with a diagnostic scan and go from there.

Thanks Dave, it's just noticeable at that lower steady speed, higher steady speeds it doesn't seem t happen, there is an occasional hesitancy to accelerate when 'floored' mind.  Think the scan step is required!

      Nothing at my injectors

      Morning Bruce Welcome to the Forum and Happy New Year You need a Scan using a good BMW capable diagnostic system. Your issue could be Crankshaft or Camshaft sensor related or High Pressure fuel pump/sensor related. If you have continuity on the Injector loom then it should be OK. I have seen two that had single injector issues due to frayed brokn wires (badly fitted loom) but cars still ran fine apart from a misfire and lack of power. Both were fixed with a new loom from BMW Hope this helps Dave

      Nothing at my injectors

      Hi, new to this group i have a 320d efficiency and over the holidays I have had issues, firstly my orange battery light saying discharging whist stationary, then it developed a misfire I know it's a diesel but that's what it felt like, anyway thought I'd take it to work has im an auto electrician. On the way there I broke down. Once check for codes something regarding start ability, tried some easy start car runs with easy start, checked fuel at fuel rail all good. I have no lives or earth's at the injectors there is no fuse wiring is about 30 inches from the ecu straight to injectors. Any ideas? T.I.A Bruce

      Morning Gary Happy New Year and Welcome to the Forum A friend of one of our sons had exactly the same issue (2020 model) he contacted his Dealer who told him No can't be done a second Dealer also said Factory Fit only. He found a company online who fitted one for him and it works really well,(I just text him for details) The company is www.autologics.co.uk he said cost was £600 all in. I have no experience of them but he is a happy bunny 😁 Hope this helps good luck Dave P.S. My daughter says you don't need a camera you have acoustic sensors backed up by a THUD when to close
