Good morning, Took the car out last night and the check engine light came on along with the engine picture. The gauges do not show a problem, nothing out of the abnormal. Gas cap is on tight. I use Esso Hi Octane Gas. Car drives fine. I have checked all of past posts on the check engine issue and it seems to be an issue with 550s, but not a serious one and nothing to get excited about. Candidly I am not very mechanical so next option is to take the car in. Question, reading the forum, this is a common 550 problem, is that the general opinion? Alican1
LOL, what a coincidence! I went to take her out for a drive last night, and same thing happened to me as well! This IS a common problem with the 550's (from what I've heard), most times its either/... -Gas cap loose (youve tried that)... -engine comp needs reset/recycle...try battery disconnect for 20 mins...then try again..might be all better! -O2 sensor on the fritz (dealer needs to check out this one) Bottom line, if youve checked your gas cap, and tried a battery disconnect and it still hasnt solved the problem...your better off taking it to the dealer. Peace of mind is a wonderful thing...its probably just a sensor, so dont take it too hard. good luck, goldy
You can get a code scanner from auto parts store for $100-150. Plug it into the OBD2 port and it'll read the code to tell you what's wrong with the car. A dealer or indept shop can do the same for you too. After you pick up the code, you can search here to find what's the cause. You can either keep the code on the car for future diagnostic or erase it with the scanner.
Just got a CEL + "the engine malfunction" light on tonight when leaving from work, cold car, no limp mode, car's running as usual. I understand that it can be anything (including a display of solidarity for the tibetans), but if it was an O2 sensor (or some other "real" problem), how damaging could it be to drive the car further ? Could I damage the cats if some of the O2 sensors are down or dirty ? I am trying to assess how urgently i need to book the car in.
After connecting an SD2, we found that there were 8 error codes in the memory. My mech suspected that the battery is getting a bit weak and that, when starting the engine, the starter runs fine but the battery voltage dips, causing the ECU to record all sorts of faults with peripherals which are otherwise running fine. We cleared the error codes, CEL has not come back since.
