Had a quick search and only found one other issue like this that concerned fitting aftermarket LED indicators and it didn't really draw any conclusions other than it was resolved finally.
But having bought some LED indicators from Motodynamics over in USA I got round to fitting them yesterday and ran into the issue of them not working when the engine is running.
Naturally when I was wiring them up I followed the instructions that were supplied and the advice I got from Motodynamics themselves who advised that no ECU flash is required for their kits to work.
So what you get in the box (be it front or rear indicators) is 2 indicators and a set of resistors.
The advice was fit the resistors to the rear set only if I was removing a standard bulb type indicator kit.
So all 4 indicators fitted with the resistors fitted to each of the rear ones, turned the ignition on and they are working absolutely fine.
Put the bike back end together again, stood back to marvel at my genius and listen to the new exhaust I had also fitted and in doing so started her up.
turn the indicators on and nothing whatsoever other than the LAMP warning on the dash.
Now the advice I have been given by Motodynamics is that it is possible that the ECU has been flashed already and that it may not need the resistors fitted to the rear LED's at all, now I am not sure that makes sense as I would have thought if the ECU was flashed for LED use already then surely if it was running normal bulbs it would have also had problems or at least been reporting something??
So I have been advised to remove the resistors and try again without and if that fails fit them to the front only, again I am not sure that fitting them to the front isn't just going to replicate the problem given that they are all part of the same circuit??
Anyone experienced this as I have found very few instances of this by searching the web so far
The bike is a 2014 so I am not sure what software upgrades have been done by BMW over that generation bike or even if it has ever been flashed with an upgrade.
My only experiences with LED indicators have been that they tend to flash too fast and need resistors when replacing bulb indicators, and for the life of me I can't see why they would work when the engine is off but fail to work with it running
