    Indy does not think it is Vanos as only 55k miles.

    Got her booked in for next Weds to get an ECU update and he is carrying out scoping on the control signals from the ECU to the coils/injectors.

    Sorry guys, another update.

    Car went in yesterday (Thurs), has the latest ECU update installed. Scoping was conducted on the coil/injector in question, all readings were good.

    Indy contacted two BMW specialists and they all agreed that it is a hydraulic lifter problem with cylinder 5, which is sort of what I suspected.

    Downside is that to replace all 24 it is getting on for £900.. Upside is that there is a product called Forte Top End Treatment, which I will be giving a go next week.
