I didn't buy a kit but yes I have the 4423 scope.

Hello, I have downloaded the software for the 4423 scope and been spending time reading the online help along with learning to navigate my way round the menus of the scope functions. On the 4423 the channels A and B say 100V peak max, I have not found any information about these two channels to date...

Well done RYM, IMV it was then

In my opinion when diagnosing faults on complex systems it is always better to follow the vehicle manufacturer recommendations, as in this case there is a fault code description present, record it check freeze frame data, clear it, run it again and see if the code and freeze frame data return, if so...

Hi Christiaan,

The ignition waveform is not performing at all well, see my previous example of what they normally look like. It may also be advantageous to have a four gas analysis completed if there is no CAT fitted. The results should help to lead you in the correct direction.

I agree, MINI fault code is 2A56 - post lambda sensor heater circuit fault. Pids show heater circuit fault on VERUS, please take a closer look.

Hi Christiaan It looks like you have set your time base settings to micro seconds [us], can you do the waveform again but set your time base in milli seconds [ms]. Try setting the scope KV at something like 20 + and the time base at 5 ms or more, redo the scope trace and see if you can achieve a ful...

Hi Kim, thanks for the additional information and the link, very much appreciated. The pid data I initially provided was from the engine idling at the workshop, if I could have run the software on this forum you would see the data changes as I drive the car, but sorry that is not possible here, howe...

Hi Kim, Thanks for replying. The front oxygen sensor to the best of my understanding is a wide band sensor and shows milli amps when switching high and low, it is indeed switching but I have no manufacturer data to compare if the tolerances are correct. The EML was illuminated and the manufacturer c...
