147 'Motor Control System Failure' after filling up...any ideas?
I bought a 2nd hand 2003 1.6 147 a few days ago, love the car but have a bit of a problem. Now my car is under warranty for 3 months so I know if I can't sort it myself I can take it back for them to fix. However I thought I check through the alfa forums first as the garage I bought it from is not an alfa garage and may not know much h about them so I thought I'd get some ideas first.
I picked the car up on Monday and it was on empty, so I filled up with £25 of petrol from Morrisons. About a mile later the motor control system failure message flashed up with the engine icon and the icon stayed on. I wasn't far from the garage I bought it from so drove their and let the guy know, he said it may be when the mechanic reset the ecu when servicing the car, he had all the books out and wasn't sure he reset it correctly, he told me to give it a few days and see if it sorted itself out as the car hadn't lost any power or performance.
I decided to do my own research and found everything from problems with lambda sensors to the battery been on its way out. However today I filled up with £20 from Sainsburys petrol station and as soon as I filled up the light went out and I no longer got the message...a mile or 2 later it come back on again and stayed on.
So is it related to the petrol? Has anyone else experienced this? Like I said the car is not lacking any performance, but I am guessing something is wrong as it worked out that it had cost about £10 to drive 30 miles...got to be wrong right?
Anyway I am in the process of resetting the ecu to see if that sorts anything out.
