Hi guys, I've gotten an unusual problem with my 749 from 2004. Last night, while driving in the freeway, the EOBD light turned on and at the same time, the engine reduced speed. Even though I held the throttle back. It turned off and the engine ran normally again. This continued for 5-7 minutes untill the oil indicator light turned on. So I quickly filled it with oil. I have 2 issues. 1. In the heat of stress and confusion, I filled up with full-synth oil. Previously it was semi-synth. Note that I havent changed the oil filter. The oil indicator shows its fully loaded and the indicator light is turned off. 2. The engine keeps on running at reduced power while the EOBD light is on. After running af few minutes its turns off, and a few minutes later it turns on again. What do I do? Can I drive it home with the EOBD light switching on and off while the oil light is off? I have about 80 kilometers home. Should I avoid highways & freeways? Regards Michael
There's no issues with the fact you mixed synthetic and semi-synth oil, it just lessens the efficacy of the synthetic oil that's all.
Turn off all power Hold down left dash/clock button Turn on ignition and keep button pressed down. This should give you the fault code/s
front cylinder behind the v panel which you will need to remove.. this behind the front wheel so both side fairings off and then this one bolt and the coil comes off. if you have the early type of coil it wont have a lead on it just a connector, get a later type coil with a fly lead remove the old lead at the connector...which might be a bitch to get at behind the battery box!!!!
Check this thread to see the coil, https://www.ducatiforum.co.uk/threads/749s-firing-on-one-cylinder.76400/ they are stick coils held in with a nut. They break down often due to either the connector or moisture gets into the coil and can't evaporate, if the latter a new coil will likely be needed
