    Engine warning light

    Hi, just about to go for a ride yesterday and the engine warning light came on . Tried it again today and still illuminated. Bike starts well and appears to run well (no noticeable difference to normal) so just wondering what it might be  - was thinking either the Lambda sensor or the exhaust valve(or its electric motor) as both look exposed to crappy road dirt. It will be going for a diagnostics check this week but just wondered if anyone had any initial ideas or had a similar problem ?

    The manual says "Engine warning light (amber), when continues light, avoid strong acceleration and high revs and go to a dealer ASAP. When the light is blinking, it may be a problem with the lambda probe or catalytic converter.
    So in general, it can be a lot of things but someone who knows Ducati's need to take a look at it.

    Keep us posted.

    Thanks - at least that rules out the Lambda if its a continuous light . I will see what the diagnostics reveal and report in due course .
    Gear position sensor had to be replaced a few weeks ago so not having a great time but its still a great bike to ride

    It could something as simple as a loose connector as a result of the last repair.

    I'm still in my 1000km break-in period, so i'm going to take her out for a spin.

    My light came on when my exhaust flapper valve went kaput. You have to disassemble a bunch of the bike to pull out the motor, so I just installed a servo buddy to get the light to turn off. Planning on getting an aftermarket exhaust at some point which would eliminate the flapper anyway...

    As is my philosophy on any modern vehicle packed full of electronics, you're doing yourself a disservice if you don't have a code scanner. CELs can be triggered by a countless array of issues, some minor some critical. The vehicle is pretty much telling you (this is what I think is wrong) so why not listen.

    You'll need a 4-pin adapter for the Multi which can then be connected to any of the code scanners out there.

    My problem turned out to be a stuck exhaust servo valve as well. My local mechanic was able to clean it up and unstick it and warning light is no longer illuminated. I have a Healtech servo eliminator on order which, for 39 and a ten minute fit time, looks like a good investment and should ensure the problem never recurs

    Mine went under warranty. The cable actuating the flap snapped. Ducati didn't even bother replacing the cable, they just fitted a bypass thing. The actual flap was solid but luckily stuck in the fully open position.
    Anything more than two wheels is unnecessary.

    Excuse my ignorance .. where is the exhaust flapper valve located?

    Wethogs, its an electro mechanical system  - the flapper valve itself being within the exhaust and operated on a short cable from a small unit located below the rear hydraulic reservoir. It is a common feature on many bikes to meet regulations and is a cause of problems for some of those also (my Gixxer included) hence many people remove them especially when an aftermarket system is being fitted

    There are at least two makes of low cost (40 approx) aftermarket electronic units for the Multi that simply plug into the existing connector - after disconnecting the valve from it - and fool the system that the valve is working

    Others on the forum are probably more mechanically knowledgeable than I am though

    My turn with the exhaust valve. Should have a servo eliminator from ebay sometime this week i hope.
