Flashing M, S & D??

So I’ve just bought a Nanocom. I managed to capture the Fault:

Code 1843 Can Timeout Monitoring

From what I’ve read it’s typically either a/c dripping on the xyz switch or oil in the red ECU plug.

Is that pretty much it for reasons? I’ve yet to extend the A/C hose, plus I’ve noticed that sometimes I need to move the selector out of park and back in before it will start. Also symptoms of a faulty xyz?

That fault code has nothing to do with the switch, oil in the ECU red plug can be a cause cos there are the CAN pins and oil can act as isolator also this fault can be triggered by voltage drop while cranking if the battery is not in the best shape

Would that explain why it only happens with the engine under load (uphill or towing) and full throttle?

OK, I am new to the D2 thing. Where is the ECU (and this red plug) ??

Might be a weak contact in the attached plug(C0162) which reacts to vibrations or heat, there are strange happenings to be oil in this plug too if the red plug was flooded, the CAN wires are the twisted yellow and the white in it(pins 5 - 6), i've seen cases when they were not twisted enough and this CAN monitoring fault kept coming on untill the owner unpinned them and twisted the wires well

Where ya jack is pop058, take ya jack out think it's a Phillips screw or 2 silver rectangular box is ecu with plugs going in it from ya left side, menouver it out and unplug the red switch block, you will notice if any oil is present [emoji2]

Look in the good oil for all of the usual reasons why the three amigos appear and how to fix them.

In the photo with the arrows, the ECU (engine control unit) is the silver box. With the TD5, the wiring harness can get congested with oil from the injector harness (follow the wiring harness from the ECU back to where it enters the engine). In the photo the front of the car is to the right (pic taken from standing at the front drivers wheel). To check if you have oil in your plugs, remove the plugs from the ECU. Spray them with contact cleaner or carby cleaner and blow them out with compressed air. Plug back in.

Weird. Ok, thanks. I’ll check them tomorrow.

I wonder if it could have anything to do with a 15p engine in a 10p car? The problem only popped up after I installed a 2nd hand ECU with the TRS remap. But then the problem may have been present before just the car lacked the power to cause the problem to manifest?

No won’t matter.

The ECU is a possibility.
vehicle power has nothing to do with the CAN bus fault.

Can you confirm battery condition and alternator output?
