Engine management indicator
I have owned a y reg 156 1.8 lusso for the past 3 years.
It is excellent in the summer but as the cold weather approaches my engine management light starts to come on.It stays on for a while then goes out.Then without warning I will switch on the engine and it will start no problem but the car will have lost accelleration I am able to move at a snails pace but no more.This can last anything from minutes to hours then it will go back to normal.
I have had the car back to the dealers but they can find no problem except what they call a glitch in the computer, but the problem persists.
Can anybody advise me?
