I recently did a bit of an overhaul on my 03 Daytona 955i. I put some iridium plugs in which seem to fix the long starting issue quite well. I also dumped the coolant and replaced it with Engine ice. Now I also replaced those crappy plastic fuel couplings with some stainless ones which work a treat. (Had to use a fuel friendly thread sealer) So I thought i might as well go the whole hog and did an oil change. After doing this I fired the bike up and it started great. But now I have that orange engine light stay on whilst it is running. With all the wires and sensors. Could I have missed something. I plugged the airbox connector in, the two to the fuel tank. The oil light goes out straight away after starting. It runs and idles well. Can someone give me some suggestions to what I might have missed or done wrong.

Badboyz10, If you turned the key on while the tank and/or airbox was removed, that will cause an illuminated MIL. Should extinguish following three engine heat cycles if all connectors are now properly connected. Otherwise you'll need a code reader (VW/AUDI compatible) or TuneECU to determine the code.

I had the tank off mine to sort a few things and when it went back on the light came on. I took it to my Triumph dealer who plugged it in and identified a wiring short somewhere in the tank wiring. He reset it but it came back on a couple of weeks later. I just ignore it now, the bike runs fine and hasn't gone into limp home mode. Eventually I might get the tank off and carefully check all the wiring but no rush unless something else goes wrong.

Well I'll be buggered. I googled your suggestion Brad and it came to another post on this forum called "BombFactory". I followed his procedure for the heat cycles and it worked. This UK machine is the weirdest piece of work I've ever had. Thanks guys for your help.

Take Brad's advice, get a cable and download TuneECU and get to the bottom of this fault code and any other that your bike throws again in the future. I think I remember seeing that some fault codes require over 60 heat cycles before it extinguishes the MIL light on the dashboard.

It isn't hard to get to this level of diagnosis and if you get a fault code that you don't know how to remedy, there are people on here far cleverer than I who can help you get to the root cause of it yourself, which is a most pleasurable experience, solving problems on the bike.

None do - all will have the light go out with 3 cycles max, PROVIDED the fault is no longer there.
However even after MIL off, most errors will remain in the ECM memory (and can be retrieved) for 40 warm-up/cool-down cycles.
But yes, TuneECU is a great tool to have - almost a must-have really - for a Fuel Injected Triumph

With FI engines (OBDI or OBDII) some sort of data analysis/tuner is just simply necessary for those that enjoy tinkering with their vehicles or for those that simply would like to know. Between my son and I we have three different DA/Ts and a wideband analyizer that we've used on our "toys". Might've saved a very expensive melt-down on the latest (arrived improperly tuned), so any expendature for the DA/T can often be recovered many, many times over.
