I have a 2004 Ford Focus 1.6 that I use most days to get me to and from work. It's very much a work horse. Last Friday while driving into the office I noticed that a warning light came on (amber coloured ring with exclamation mark). Apart from the light being illuminated all seemed well - temperature ok etc and the engine felt normal. It went out before I completed my journey. That same day when driving home it illuminated again through my 20 mile of mostly motorway drive home. I didn't use the car most of the weekend but then popped out last night for a short run to the shops and noticed that another light was on, this time the amber coloured picture of an engine. As I drove home the engine started to lose power and sound quite rough. I went to the car this morning to take a better look and noticed the coolant level was low but hadn't previously noticed that the engine temperature gauge was above normal. So, topped the coolant up but now the light is continuously on (engine pic in amber) and it feels rough after warming up. I'm a big fan of forums of this type but have never needed to join a Focus related one before, generally the car has been reliable. Any suggestions welcome? Cheers.
