2.0 JTS Motor Control System Failure
I have a 2003 156 2.0 JTS.
I get the "Motor Control System Failure" message come on the dash with beeping sometimes when starting up, but only first thing in the morning when it is very cold outside and frost on the ground.
It goes off straight away, and doesn't come on again until next time I start it on a cold morning.
I have checked for fault codes using a diagnostic scanner, but there are no fault codes present.
The performance of the car is not affected in anyway.
The only thing is that when starting up very cold, there is a lot of white vapour coming out the back, a lot more than my old car when starting cold. It goes on for about 15 minutes, then it is fine when warmed up.
Is this anything to worry about?
