Motor control system failure
Hi, new to the site, hope you can help! I have a 147 2.0 Lusso Selespeed.
Firstly, I know there are already some threads on this subject and I've read most of them, but the problems people seem to experience are so varied that I was hoping for some more "focused" answers.
I have this light on - but I'm not experiencing any lack of power, I've not noticed any water loss (and the oil looks good) and no limp home mode as of yet. Car seems to run fine, just with the annoying light and beep on. It didn't gradually come on over time (i.e be on then disappear etc) it was just on one day and has been on since.
Was just wondering if anyone has any ideas what this could be? Would it be something as simple as the battery (or would that usually be a gradual thing?). If it were crankshaft sensor or MAF would I necessarily experience any power loss?
Your help would be fantastic since I'd rather have an idea of problem before huge garage costs! lol
